Under California law, hospitals must provide emergency room services without regard for a patient’s ability to pay or who will ultimately bear responsibi lity for the medical bill. ( Prospect Medical Group, Inc. v. Northridge Emergency Medical Group (2009) 45 Cal.4th 497, 501

- 502 ( Prospect ). ) Depending on who pays the bill for emergency room services, billing rates for the same treatment can vary substanti ally. ( Howell v. Hamilton Meats & Provisions, Inc . (2011) 52 Cal.4th 541, 552, 560 ( Howell ). ) After patients have received their care, hospitals often face the difficult and complex task of trying to secure payment for the emergency room services. The f inal cost and identity
of the responsible payer of the emergency room services can remain unresolved for years. Sometimes a patient needs emergency room care due to negligent driving by a third party tortfeasor with automobile liability insurance coverag e. In such an instance, the hospital with the emergency room must determine whether the medical bills are the responsibility of the patient, the patient’s health care service plan, the tortfeasor, the tortfeasor’s liability insurer, or some combination of these potential payers. ( Prospect,

supra, 45 Cal.4th at pp. 501

- 502; Parnell v. Adventist Health System/West (2005) 35 Cal.4th 595, 598 ( Parnell ); Health & Saf. Code, § 1371.4, subd. (b).) Further complicating a hospital’s endeavor to bill for emergency room services are varying limits on financial responsibility for the medical services. A patient’s financial responsibility may be limited to the copayment amounts specified by the health care service plan. ( Parnell, at p. 611, fn. 15.) The patient’s h ealth care service plan may be limited to paying a negotiated rate that is less than the hospital’s customary billing rate. 1 ( Id. at

1 We refer to the lower billing rates payable by health care service plans having contracts with hospitals as “negotiated rates.” Although negotiated rates are lower than the “ customary rates” charged for emergency room services, they do not necessarily constitute “ discount ” rates. The California Supreme Court has explained that “if it were established a medical provider’s full bill generally represents the value of the service s3

p. 609.) Many hospitals enter into contracts with health care service plans to ensure sufficient volume for their emergen cy rooms and in turn pass along the savings for “buying in bulk” the emergency room services provided. While many health care service plans contract for such negotiated rates, most automobile liability insurers do not. The health care service plan in th is case, Kaiser Permanente (Kaiser), covered three patients who received care at an emergency room operated by Dameron Hospital Association (Dameron). The patients were injured due to the negligence of third party tortfeasors who had automobile liability insurance with California Automobile
Association Inter

- insurance Bureau (AAA) 2 and Allstate Insurance Company (Allstate). Unlike Kaiser, neither AAA nor Allstate has contracts with Dameron. In the absence of an agreement for negotiated billing rates, Dam eron sought to collect from AAA and Allstate its customary billing rates by asserting liens filed under the Hospital Lien Act (HLA ). ( Civ. Code, § 3045.1 et seq.) AAA and Allstate, however, ignored Dameron’s HLA liens when paying settlements to the three Kaiser patients. Upon learning of the settlements, Dameron sued AAA and Allstate to recover on its HLA liens. The trial court granted the automobile liability insurers’ motions for summary judgment on grounds the patients’ debts had already been fully satisfied by their health care service plans. Reasoning the HLA liens were extinguished for lack of any underlying debt, the trial court dismissed the case. The trial court further found dismissal was warranted because Dameron failed to timely file some of its HLA liens against AAA.

provided, and the discounted price negotiated with the insurer is an artificially low fraction of that true value, one could make a parallel argument that relieving the defendant of paying the full bill would result in underdeterrence. The complexities of contemporary pricing and reimbursement patterns for medical providers, however, do not support such a generalization.” ( Howell , supra , 52 Cal.4th at p. 560.)

2 California Automobile Association Inter

- insurance Bureau is now named AAA Northern Californi a, Nevada and Utah Insurance Exchange.4

The central question presented in Dameron’s appeal is this: Does a health care service plan’s payment of a previously negotiated rate for emergency room services insulate the tortfeasor’s automobile liability insurer from h aving to pay the customary
rate for medical care rendered? AAA and Allstate contend they are not responsible for

any amount after Kaiser paid in full the bill for the emergency room services provided by Dameron. Dameron responds that it contracted with K aiser to preserve its rights to recover the customary billing rates from tortfeasors and their automobile liability insurers. Dameron asserts the tortfeasors and their liability insurers are responsible for
the entire bill for medical services at the cust omary rate

– - not just the difference between the reimbursement received from Kaiser and the customary billing rate.
In Parnell, supra, 35 Cal.4th 595, the California Supreme Court unanimously held hospitals may not recover their customary rates for emer gency room care when they have contractually agreed to accept negotiated rates as payment in full. ( Id. at p. 609.) In so holding, the Supreme Court acknowledged that “California hospitals face mounting financial pressures, and that many, if not all, of these hospitals may ‘face a genuine financial crisis that threatens their ability to continue to serve their communities.’ ” ( Id. at p. 611.) Parnell noted its holding might “result in a significant hardship for many of these hospitals.” ( Ibid. ) To all eviate such hardship, the Supreme Court stated hospitals could turn to the Legislature for changes to the HLA. ( Id. at p. 611.) More importantly for purposes of this case, the Parnell court held that “the solution lies in the hands of the hospitals. By precluding the Community Hospital from asserting a lien under the HLA in this case, we ‘simply give[] effect to’ its contracts. ( Lopez v. Morley [(2004)] 817 N.E.2d [592,] 599.) If hospitals wish to preserve their right to recover the difference between usual and customary charges and the negotiated rate through a lien under the HLA, they are free to contract for this right. Our decision today does not preclude hospitals from doing so. (See, e.g., Andrews [ v. Samaritan Health System (Ct. App. 2001)] 36 P.3d [57,] 61.)” ( Parnell , supra , 35 Cal.4th at p. 611.)5

Although Dameron claims it should benefit from the California Supreme Court’s holding that it may avoid extinguishment of its HLA liens upon receiving payments from health insurers, the contract in this case preceded Parnell by 10 years. The
Dameron/Kaiser contract did not seek to avail itself of the Parnell court’s guidance. Instead, the Dameron/Kaiser contract is silent as to whether Dameron may collect from
tortfeasors and their automobile in surers after receiving negotiated rate payments from the patients’ health care service plans. Dameron attempts to supply the contract term by relying on a history of “uniform conduct” in which Dameron and Kaiser have cooperated in seeking payment from thi rd party tortfeasors and their liability insurers. We conclude the Dameron/Kaiser contract does not contain the term described by
the Parnell court as sufficient to preserve the right to recover the customary billing rate for emergency room services from third party tortfeasors. To paraphrase Parnell , if Dameron wishes to preserve its right to recover its customary billing rates through an HLA lien, it is free to contract for this right. ( Parnell, supra, 35 Cal.4th at p. 611.) But
Dameron must actually contract for this right. ( Ibid. ) A history of voluntary cooperation
with Kaiser does not suffice to avail Dameron of the Parnell court’s guidance on reservation of contractual rights under the HLA. Consequently, the trial court properly granted summary judgment in favor of AAA and Allstate. Because we affirm the granting of summary judgment for lack of contractual reservation of billing rights against third party tortfeasors, we do not reach the question of whether all of the HLA liens in
this case wer e timely filed by Dameron.
BACKGROUND Dameron’s Claims Against AAA and Allstate In July 2010, Dameron sued AAA and Allstate for damages as well as injunctive and declaratory relief. Dameron’s complaint alleges it gives emergency room care to patients rega rdless of their ability to pay, as required by Health and Safety Code section6

1317. Thus, Dameron provided emergency room services to Denise H. 3 and Don P. The bill for Denise H. amounted to $1,724 and Don P.’s bill was $3,445. After these patients

were discharged from the emergency room, Dameron learned each was injured by the negligence of a driver insured by Allstate. Dameron also provided emergency room services to Rita H., Sara M., and D

. S. Rita H.’s emergency room bill totaled $33,831.74, Sara M .’s was $1,976, and D

. S.’s was $2,029.76. After these patients were discharged, Dameron learned they were all injured by drivers insured by AAA. The record indicates Kaiser provided health insurance for each of these patients except Rita H. and D

. S. Fo r each of these patient’s emergency room services bills Dameron served HLA liens on all entities known to Dameron and who might be liable for causing each patient’s injuries. And, for each of these patients, Dameron learned AAA or Allstate paid a settleme nt to the patient without satisfying any part of Dameron’s HLA liens. Dameron filed the present action within a year of learning of the settlements and judgments. Dameron further alleges each of the contracts with health care service plans for the patie nts in this case contains an “applicable rate agreement” that “preserves Dameron’s HLA rights, as contemplated by the California Supreme Court in Parnell [, supra, 35 Cal.4th at p. 611].” Dameron asserts it follows the same procedure in collecting on its
H LA liens whenever a third party has caused injury to an emergency room patient who has coverage with a health insurer having a rate agreement contract with Dameron. Specifically, Dameron bills the full amount of the emergency room costs to the injured pat ient’s health plan per Dameron’s contract with the health plan. Dameron also bills the

full amount of emergency room costs to the third party tortfeasor and/or tortfeasor’s liability insurer by serving an HLA notice under Civil Code section 3045.3. 4
If the tortfeasor, tortfeasor’s liability insurer, or any responsible party pays Dameron’s HLA claim before the patient’s health care service plan pays Dameron the negotiated rate, Dameron cancels its bill to the patient’s health care service plan. However, if the patient’s health plan pays the negotiated rate under the applicable rate agreement before any other responsible party pays under the HLA lien, Dameron “holds the health plan’s payment in abeyance (as well as any co

- payment received from the injured patient), pending resolution of Dameron’s HLA claim.” If Dameron recovers money on its HLA claim following payment from the patient’s health care service plan, Dameron refunds the patient’s copayment and then refunds the health care service plan
from the proceeds of the HLA lien recovery. If there are any proceeds remaining after reimbursements to the patient and patient’s health plans, Dameron keeps the remainder. In any event, Dameron does not “attempt to collect or retain more than its reasonable and necessary charges in any patient’s account.” Dameron’s complaint also alleges payments of settlements and judgments to patients while ignoring HLA liens “are not isolated or random events. Rather the HLA violations . . . are part of an industry

- wide bus iness strategy adopted primarily by automobile liability insurers in California . . . and by other similarly situated responsible parties under the HLA.” In addition to violating the HLA, Dameron claimed the

4 In other words, Dameron does not seek to “balance bill” tortfeasors or their liability insurers for the difference between the negotiated rates paid by health care service plans and the customary rate Dameron would ordinarily charge. Instead, Dameron seeks to recover the entirety of its customary rates from the tortfeasors and their liability insurers.8

practices also violated the Unfair Competition Law (Bus. & Prof. Code, § 17200 et seq.)

. 5 Motions for Summary Judgment
AAA and Allstate each moved for summary judgment, arguing Dameron could not recover anything under the HLA liens because the underlying debts had been extinguished by payments in ful l by the patients’ health plans. AAA also argued two of the three claims asserted by Dameron were time

- barred. In support of its motion, Allstate introduced the Dameron/Kaiser agreement for the provision of hospital services to Kaiser patients. The Dam eron/Kaiser contract , effective January 1, 1995 , provides in pertinent part:
“3. Member Billing

. [¶] (a) Hospital shall look solely to Kaiser Permanente (or another responsible payer) for compensation for Hospital Services rendered to Members
under t his Agreement, and, except as expressly provided in this Section, Hospital agrees that in no event, including but not limited to non

- payment by Kaiser Permanente, insolvency or breach of this Agreement, shall Hospital bill, charge, collect a deposit from, seek compensation, remuneration or reimbursement from, or have any recourse against any Member for Hospital Services provided pursuant to this Agreement. Hospital further agrees that this provision shall (i) survive the termination of this Agreement
regar dless of the cause giving rise to termination and shall be construed to be for the

5 Dameron urges us to consider the judgment entered in an earlier class action lawsuit titled Ruacho, et al. v. Dameron Hospital Association (Superior Court San Joaquin County (2012) SV231473), not as “controlling authority in any manner” but to supply “a historical perspective , because it is part and parcel of the uniform performance of the Dameron/Kaiser contract in regard to HLA claims.” We decline to do so. As Dameron acknowledges, the trial court’s decision in that case cannot be cited as legal authority. ( Bolanos v. Sup erior Court (2008) 169 Cal.App.4th 744, 761.) Moreover, the outcome of the earlier and unrelated case does not constitute evidence in this case. ( Johnson & Johnson v. Superior Court (2011) 192 Cal.App.4th 757, 768.)9

benefit of the Members, and (ii) supersede any oral or written contrary agreement now existing or hereafter entered into by the parties. [¶] (b) Hospital may assert claim s for compensation other than claims against Kaiser Permanente, in the following circumstances: [¶] (i) Copayments . . . . [¶] (ii) Services After Coverage Exhausted or
Disallowed . . . . [¶] (iii) No benefit

. . . . [¶] (iv) Regular Medicare

. . . . [¶] (c) Hospital understands and agrees that surcharges against Members are prohibited and Kaiser Permanente shall take appropriate action if surcharges are imposed. A surcharge is an additional fee which is charged to a Member for a covered Hospita l Service but which is not approved by the Commissioner of Corporations or provided for under the applicable Membership Agreement and disclosed in the Member’s evidence of coverage.” Dameron opposed summary judgment on grounds the Dameron/Kaiser contract allowed collection of the HLA liens against AAA and Allstate. Dameron also asserted its claims against AAA were not time

- barred because the hospital filed the HLA lien notices within a year of discovering the identity of the responsible payers.
The tri al court granted summary judgment in favor of AAA and Allstate . The trial court reasoned Kaiser’s payment of an agreed

- upon rate for emergency room payments extinguished the debt owing to Dameron and had the effect of also extinguishing the
HLA liens. As to two of the claims against AAA, the trial court found the discovery rule did not apply to render the HLA claims timely. Dameron timely filed notices of appeal from the judgments of dismissal.
DISCUSSION
I Standards of Review We apply the independent standard of review to the trial court’s order granting summary judgment. ( Guz v. Bechtel National, Inc. (2000) 24 Cal.4th 317, 334.) As this

court has noted, “We review the issues framed by the pleadings to determine the scope of10

the issues tendered and to determine whether the moving party has established facts negating the opponent’s claim and justifying a judgment in the moving party’s favor. ( AARTS Productions, Inc. v. Crocker National Bank (1986) 179 Cal.App.3d 1061, 1064

– 1065.) In so doing we det ermine whether the opposition to the motion demonstrates the existence of a triable issue of material fact. ( Ibid .) We review the evidence in the light

most favorable to the opposition to the motion, and liberally construe the opposition’s evidence, whil e strictly scrutinizing the successful party’s evidence and resolving any evidentiary ambiguities in the opposition ’ s favor. ( Saelzler v. Advanced Group 400 (2001) 25 Cal.4th 763, 768.)” ( Avidity Partners, LLC v. State of California (2013) 221 Cal.App.4t h 1180, 11 92 .) We also independently review contractual agreements, including the question of whether the language used in a contract is ambiguous. ( American Alternative Ins. Corp. v. Superior Court (2006) 135 Cal.App.4th 1239, 1245.) Finally, “[w]e are not bound by the trial court’s reasons for granting summary judgment because we review the trial court’s ruling, and not its rationale. ” ( Avidity, supra, at
p. 11 92 .)
II The HLA as Interpreted in Parnell Dameron’s right to recover its customary rates for emergency room services from third party tortfeasors and their liability insurers depends on whether the hospital’s HLA liens are extinguished when accepting payments by the emergency room patients’ health care service plans. The HLA provides a hospital with a statutory lien against any judgment, settlement, or compromise paid by a third party tortfeasor or tortfeasor’s liability insurer to a patient who received emergency room care. ( Parnell , supra , 35 Cal.4th at p. 598; Civ. Code, § 3045.2.) Civil Cod e section 3045.1 states a hospital that “furnishes emergency and ongoing medical or other services to any person injured by reason of an accident or negligent or other wrongful act . . . shall, if the person has a claim against another for damages on accou nt of his or her injuries, have a lien upon the11

damages recovered, or to be recovered, by the person, or by his or her heirs or personal representative in case of his or her death to the extent of the amount of the reasonable and necessary charges of the h ospital.” For the HLA lien to become effective, the hospital must serve written notice of “the amount claimed as reasonable and necessary charges” on each person or entity “known to the hospital and alleged to be liable to the injured person

. . . for th e injuries sustained prior to the payment of any moneys to the injured person.” (Civ. Code, § 3045.3.) The HLA notice must also be served on any known liability insurers responsible for the actions of the alleged tortfeasors. ( Ibid. ) However, the hospi tal need not provide notice of the HLA lien to the emergency room patient. ( Parnell , supra , 35 Cal.4th at p. 601.) Tortfeasors and their liability insurers are required to satisfy the HLA lien at the same time as they pay any money to the emergency room p atients. As the Parnell court explained, “If the tortfeasor pays the injured person ‘after the receipt of the notice as provided by [Civil Code] Section 3045.3, without paying to the’ hospital ‘the amount of its lien claimed in the notice, or so much ther eof as can be satisfied out of 50 percent of the moneys due under any final judgment, compromise, or settlement agreement,’ then the tortfeasor ‘shall be liable to the’ hospital ‘for the amount of its lien claimed in the notice which the hospital was entit led to receive as payment for the medical care and services rendered to the injured person.’ ([Civ. Code,] § 3045.4.)” ( Parnell , supra , 35 Cal.4th at pp. 601

- 602.) This statutory penalty payment to the hospital does not come from recovery of funds paid to the injured patient, but must be paid separately by the tortfeasor or tortfeasor’s liability insurer. ( Mercy Hospital & Medical Center v. Farmers Ins. Group of Companies (1997) 15 Cal.4th 213, 221.) The HLA creates a statutory lien that “is ‘nonconsens ual’ and ‘compensates a hospital for providing medical services to an injured person by giving the hospital a direct right to a certain percentage of specific property, i.e., a judgment, compromise, or12

settlement, otherwise accruing to that person.’ ( Ibid .)” ( Parnell , supra , 35 Cal.4th at
p. 602.) Parnell further notes that, “[a]s a general rule, ‘[a] lien is a charge imposed in some mode other than by a transfer in trust upon specific property by which it is made security for the performance of an act.’ ([Civ. Code,] § 2872.) Because ‘[a] security interest cannot exist without an underlying obligation’ ( Alliance Mortgage Co. v.
Rothwell (1995) 10 Cal.4th 1226, 1235), a lien is typically ‘but an incident of the debt secured’ ( Lewis v. Booth (1935) 3 Ca l.2d 345, 349) and ‘presupposes the existence of a debt’ ( Dorr v. Sacred Heart Hosp . (1999) 228 Wis.2d 425, 597 N.W.2d 462, 470 ( Dorr )).” ( Parnell , supra , 35 Cal.4th 595, 602

- 603.) The typical dependence of a lien on an underlying debt led the Parnell c ourt to conclude payment of the underlying debt

– - such as by an injured patient’s health plan

– - extinguished the hospital’s HLA lien. ( Parnell , supra , 35 Cal.4th 595, 602

- 603.) Thus, a hospital’s acceptance of “payment in full” from a health care servi ce plan relieved the third party tortfeasor and his or her liability insurer from any further payment under the HLA. ( Ibid. ) However, the Parnell court noted hospitals could contractually preserve the right to recover their usual and customary rates from tortfeasors and their liability
insurers. Parnell states that “[i]f hospitals wish to preserve their right to recover the difference between usual and customary charges and the negotiated rate through a lien under the HLA, they are free to contract for t his right.” ( Id. at p. 611.) Parnell further noted neither the Insurance Code nor the Health and Safety Code “precludes hospitals from contractually preserving their right to recover ‘ reasonable and necessary charges’ pursuant to a lien under the HLA.” ( Id. at p. 611, fn. 15.)
The Parnell court’s unanimous conclusion that hospitals can contractually reserve the right to recover customary emergency room billing rates from third party tortfeasors delineates the extent of its holding that a hospital’s acc eptance of payment in full from a health care services plan extinguishes any HLA lien premised on the same debt. ( Parnell , supra , 35 Cal.4th at p. 611 & fn. 16 [noting its “holding relies solely on the13

absence of a debt underlying the lien” and does not e xtend to resolving issues of whether the HLA applies in the Medicaid context, violates due process, is subject to waiver by hospitals, or is subject to litigation immunity]. ) Contrary to respondents’ suggestion,
Parnell’s statements regarding the availabi lity of contractual remedies for hospitals were
not mere dicta. The Parnell court’s guidance regarding contractual options “was responsive to the issues raised on appeal and was intended to guide the parties” and lower courts in addressing HLA issues in t he future. ( Garfield Medical Center v. Belsh é (1998) 68 Cal.App.4th 798, 806.) We are bound to follow the S upreme Court’s holdings. ( Auto Equity Sales, Inc. v. Superior Court (1962) 57 Cal.2d 450, 455.) In holding California hospitals may contractually reserve the right to recover their customary billing rates from third party tortfeasors, the Parnell court cited the example of
Andrews v. Samaritan Health System (Ct.App. 2001) 36 P.3d 57, 6 1 ( Andrews ) , disapproved on another ground in Blankenbaker v. Jon ovich (2003) 205 Ariz. 383, 385

- 386, 71 P.3d 910, 912

- 913

. 6 ( Parnell , supra , 35 Cal.4th at p. 611.) In Andrews, the Arizona Court of Appeals held injured patients could not prevent hospitals from balance billing by enforcing statutory medical liens on ju dgments received from third

- party tortfeasors. (

Andrews, supra, at p. 59 .) In so holding, the Andrews court provided two rationales. ( Id. at p. 61 .) One rationale was Arizona Revised Statutes, section 33

– 931, automatically created a medical lien provid ing that “a [hospital] provider ‘is entitled to a lien for the customary charges for care and treatment . . . of an injured person’ without specifying further action by the hospitals.” ( Andrews, supra, at p. 61 .)

6 Remarkably, none of the parties nor amici curiae mentions Andrews , supra, 36 P.3d 57 in any of their extensive briefing on the meaning and continuing validity of Parnell’s holding hospitals have the ability to contractually retain their right to seek their customary rates for emergency room services.14

The other rationale in Andrews arose fro m the language of the contracts between the defendant hospitals and the patients’ health care services plans. Andrews explained that “the instant contracts each contained language stating that the hospitals accepted the plaintiffs ’ insurer’s payment as ‘p ayment in full,’ and all . . . expressly reserved the right to recapture the difference between any payments made by the insurer and the providers ’ customary charges . Unlike the contracts in the cases from other jurisdictions, this reservation clearly qua lifies the ‘payment in full’ language and sets forth the hospitals’ expectation to recover their customary charges when possible.” ( Andrews , supra , 36 P.3d at pp. 60

- 61, italics added.) As a consequence, “[t]he fact that the hospitals have no personal re course against plaintiffs, by virtue of their insurance coverage, does not alter the fact that a debt remains between the hospitals’ customary charges and the amounts paid by plaintiffs ’ insurers.” ( Id. at p. 61 .) This contract

- based rationale for preser ving a hospital’s right to recover its customary charges from third

- party tortfeasors was cited with approval by the California Supreme Court in Parnell , supra , 35 Cal.4th at p. 611. Notably, the patients in Andrews , supra , 36 P.3d 57 did not have their re coveries from third party tortfeasors reduced by the hospitals’ ability to recover their customary charges when the patients’ health plans paid only a negotiated rate because “[i]n their various personal injury suits, plaintiffs all quantified their damage s by including the hospitals’ full charges for medical services, rather than the discounted amount paid by their insurers.” (

Andrews , supra , 36 P.3d at p. 59.) In other words, plaintiffs in Andrews were able to claim damages in the amount of customary ra tes based on the express contracts between the hospitals and the health care service plans. ( Ibid. ) The Andrews plaintiffs nonetheless argued the hospitals’ reservation of rights to customary rates constituted an unfair assignment of their personal injur y claims against the third party
tortfeasors. The Andrews court rejected the argument, explaining that “[t]he legislature, in limited circumstances, may abrogate the rule against assigning tort claims. [Citation.] The medical lien statute represents the l egislature’s abrogation of that rule. The15

abrogation effected by the medical lien statute serves to ease the financial burden on providers and to encourage hospitals to render emergency care to patients without regard to ability to pay. [Citation.] He re, the plaintiffs’ insurers did not assign any rights to the hospitals. Rather, the right to the medical liens springs from [Arizona Revised Statutes] § 33

– 931. We see no reason to invalidate the medical lien statute as written by the legislature given its obvious value and purpose.” ( Andrews , supra , at p. 63.) Taken together , Parnell , supra, 35 Cal.4th 595 and Andrews allow for statutory medical liens to recover customary billing rates for emergency room services if the hospital has an express contract with the health care service plan to that effect.
III Parnell’s Continuing Validity AAA and Allstate argue Parnell , supra, 35 Cal.4th 595 is no longer valid authority for the proposition that hospitals can contractually reserve the right to recover their customary rates even after being paid the negotiated rate by injured patients’ health plans. In so arguing, AAA and Allstate rely on the Knox

- Keene Health Care Service Plan Act of 1975 (Knox

- Keene Act ) ( Health & Saf. Code, § 1340 et seq.) and the Californ ia Supreme Court’s subsequent decisions in Prospect, supra, 45 Cal.4th 497 and Howell, supra, 52
Cal.4th 541. We conclude these authorities do not undermine Parnell’s holding that hospitals may contractually preserve their right to recover their customary rates from third party tortfeasors and their liability insurers. California hospitals are required to provide emergency care without regard to the injured patient’s ability to pay. (Health & Saf. Code, § 1317, subd. (d).) The treating hospital may requi re only that “the patient or his or her legally responsible relative or guardian . . . execute an agreement to pay therefor or otherwise supply insurance or credit information promptly after the services are rendered.” ( Ibid. ) The Knox

- Keene Act requires health plans to reimburse hospitals for emergency care even if the hospital is not16

included in the health care service plan’s network. (Health & Saf. Code, § 1371.4,
subds. (a) & (d).)
The Knox

- Keene Act also includes the following patient

- protection p rovisions: “(a) Every contract between a plan and a provider of health care services shall be in writing, and shall set forth that in the event the plan fails to pay for health care services as set forth in the subscriber contract, the subscriber or enrol lee shall not be liable to the provider for any sums owed by the plan. [¶] (b) In the event that the contract has not been reduced to writing as required by this chapter or that the contract fails to contain the required prohibition, the contracting prov ider shall not collect or attempt to collect from the subscriber or enrollee sums owed by the plan. [¶] (c) No contracting provider, or agent, trustee or assignee thereof, may maintain any action at law against a subscriber or
enrollee to collect sums ow ed by the plan.” (Health & Saf. Code, § 1379 ( S ection 1379).) We reject the contentions of AAA and Allstate that section 1379 insulates them from balance billing by hospitals. Section 1379 does not mention balance billing, third party tortfeasors, or lia bility insurance companies. Instead, the statute mentions only health care service plans, providers of medical care, and patients. The clear import of section 1379 is to protect patients with health care service plan coverage from any collection attempts by providers of such medical care as emergency room services. Section 1379’s patient protections were examined by the California Supreme
Court in Prospect

, supra, 45 Cal.4th 497

. Prospect involved billing disputes between health care service plans and em ergency room physicians with whom they did not have preexisting contractual relationships. (45 Cal.4th at p. 503.) The health care service plans argued the Knox

- Keene Act (along with other provisions of law) prevented the emergency room physicians from b illing the patients for the difference between the bill submitted and the amount paid by the health care service plans. ( Id. at pp. 501, 505.) Thus, the question presented for the S upreme Court was whether the lack of contract
between the health care ser vice plans and the emergency physicians precluded section17

1379’s prohibition on “balance billing”

– - i.e., billing for the difference between the usual and customary rate and the negotiated rate paid. ( Id. at pp. 505

- 506.)
The Prospect court concluded t he Knox

- Keene Act precludes any attempt to bill patients for the amount exceeding the negotiated rate paid by health care service plans. ( Prospect, supra, 45 Cal.4th at p. 502.) Instead, the health care service plans and emergency room physicians are req uired to resolve their billing disputes without injecting their patients into the process. ( Ibid. ) On this point, the Prospect court noted that “the Legislature contemplated there may be disputes over the amounts owed to noncontracting providers such as emergency room doctors, and therefore the Knox

– Keene Act requires that each [health maintenance organization] ‘shall ensure that a dispute resolution mechanism is accessible to noncontracting providers for the purpose of resolving billing and claims disput es.’ (§ 1367, subd. (h)(2); see also § 1371.38, subd. (a) [directing the Dept. of Managed Health Care to adopt regulations ensuring that each HMO adopt a dispute resolution mechanism that is ‘fair, fast, and cost

- effective for contracting and
noncontracti ng providers’].)” ( Prospect, supra, at p. 507.) Ultimately, however, “[a] patient who is a member of an HMO may not be injected into the dispute.” ( Id. at
p. 502.) The California Supreme Court’s decision in Prospect does not mention its earlier
case of Parnell

, supra, 35 Cal.4th 595

. (See Prospect , supra , 45 Cal.4th at pp. 497

- 511

. ) This omission is explained by the fact Prospect did not involve any claim of recovery against third party tortfeasors or their liability insurers. ( Ibid. ) “An opinion is not authority for a point not raised, considered, or resolved therein.” ( Styne v. Stevens (2001) 26 Cal.4th 42, 57.) Nothing in Prospect abrogates Parnell’s holding that hospitals may contract with health care service plans to preserve rights to recover customary billing rates via HLA liens against third party tortfeasors. We reject AAA’s argument that the California Supreme Court’s decision in Howell, supra, 52 Cal.4th 541 overruled its earlier statement in Parnell that hospitals18

may contract with healt h care service plans to preserve the right to balance bill third party
tortfeasors. Howell involved the question of whether an injured patient could sue a tortfeasor for damages that included the customary charges for emergency room care billed by the hos pital. ( Id. at p. 548.) The Howell court concluded that when the hospital has accepted a lesser amount as full payment under the terms of a prior agreement with the health care service plan, the injured patient could only recover this negotiated rate. ( Ibid. )
Howell explains that “[t]he collateral source rule, which precludes deduction of compensation the plaintiff has received from sources independent of the tortfeasor from damages the plaintiff ‘would otherwise collect from the tortfeasor’ [citation] , ensures that plaintiff . . . may recover in damages the amounts her [or his] insurer paid for her [or his] medical care. The rule, however, has no bearing on amounts that were included in a provider’s bill but for which the plaintiff never incurred liab ility because the provider, by prior agreement, accepted a lesser amount as full payment. Such sums are not damages the plaintiff would otherwise have collected from the defendant. They are neither paid to the providers on the plaintiff ’ s behalf nor paid to the plaintiff in indemnity of his or her expenses. Because they do not represent an economic loss for the plaintiff, they are not recoverable in the first instance.” ( Howell, supra, 52 Cal.4th at pp. 548

- 549.)
Howell addressed whether a patient cou ld recover the customary billing rate from a tortfeasor, whereas this case involves a claim by the hospital against tortfeasors and their liability insurers. ( Howell, supra, 52 Cal.4th at p. 548.) In every instance in which
Howell articulated its holding , the S upreme Court noted the hospital in that case agreed the negotiated rate constituted payment in full. ( Id. at pp. 548 [collateral source did not apply because hospital agreed to accept negotiated rate as full payment], 554 [hospital accepted negotia ted rate of “$3,600 in full payment for its services to the plaintiff”].) Rather than overruling Parnell , the S upreme Court in Howell repeatedly cited its earlier decision with approval. In each of the four instances in which Howell cited19

Parnell , the C alifornia Supreme Court expressly noted Parnell involved a situation in which the hospital accepted a negotiated rate as payment in full. ( Howell, supra, 52 Cal.4th at pp. 554, 557, 558, 563.) For example, the Howell court noted it “reached the

same conc lusion in Parnell

. . . , holding the hospital could not assert a lien against a patient’s tort recovery for its full bill when it had agreed to accept an insurer’s lesser reimbursement as full payment.” ( Howell , supra , 52 Cal.4th at p. 554, italics added .) Similarly, Howell reiterated its holding that, “[h]aving agreed to accept the negotiated amount as full payment, a provider may not recover any difference between that and the billed amount through a lien on the tort recovery. ( Parnell

. . . , supra , 35 Cal.4th at
p. 598.)” ( Howell , supra, 52 Cal.4th at p. 558.) Based on the hospital’s accept ance of a negotiated rate as payment in full, Howell concluded that “[p]laintiff cannot meaningfully be said ever to have incurred the full charges. (See Parnel l

. . . , supra , 35 Cal.4th at
p. 609 [where hospital had agreed with plaintiff’s health plan to accept discounted amounts as payment in full, plaintiff owed hospital nothing beyond those discounted payments] . . . .)” ( Howell , supra , at p. 557.) In shor t, Howell does not overrule the
Parnell court’s statement that hospitals have the ability to enter into agreements with health care service plans that preserve the right to recover customary rates from tortfeasors for emergency room care provided.
We are a lso not persuaded by AAA that its interpretation of Howell , supra, 52
Cal.4th 541 was confirmed in Corenbaum v. Lampkin (2013) 215 Cal.App.4th 1308 ( Corenbaum ). AAA argues Corenbaum stands for the proposition that “the tortfeasor, and by extension his [or her] insurer, is not liable for the delta between what the hospital ‘charged’ and what it accepted from the health insurer.” AAA overstates the scope of
decision in Corenbaum . The Corenbaum court expressly noted that: “As in Howell , the medical provide rs who treated plaintiffs . . . accepted, pursuant to prior agreements, less than the full amount of their medical billings as payment in full for their services.” ( Corenbaum, supra, at p. 1318.) Based on the similarity in the hospitals’ acceptance of20

th e negotiated rate as payment in full, Corenbaum holds evidence of the customary rate for emergency room services may not be introduced at trial to prove medical expenses or noneconomic damages when the hospital accepted full payment in a lesser amount. ( I d. at p. 1318 .) Also based on the Supreme Court’s guidance in Howell , the Corenbaum court reasoned that “[a]n insured plaintiff incurs no liability for the negotiated rate differential and suffers no pecuniary loss in that amount.” ( Corenbaum , at p. 132 5.) Thus, “[e]vidence of the full amount billed . . . is not relevant to the amount of damages for past medical expenses if the plaintiff never incurred liability for that amount.” ( Id. at
p. 1327.) As in Howell , the decision in Corenbaum did not involv e any action by the hospital against the third party tortfeasor or tortfeasor’s liability insurer. Based on our survey of decisional authority following the S upreme Court’s
unanimous decision in Parnell , supra , 35 Cal.4th 595, we conclude no case undermine s Parnell’s guidance to hospitals that they may preserve the right to recover from a third party tortfeasor the differential between the negotiated rate paid by an injured patient’s health care service plan and the customary rate billed for the emergency r oom services. Moreover, neither the HLA nor applicable provisions of Knox

- Keene ha s been amended by the Legislature since the Supreme Court’s 2005 decision in Parnell . ( Civ. Code, §§ 3045.2, 3045.3, 3045.4 [pertinent HLA statutes]; § 1379 [pertinent Knox

- Keene statute]. ) Thus, the Legislature has not changed how the HLA statutory lien operates either in substance or procedure since the Parnell court examined the HLA statutory scheme. In short, Parnell remains valid insofar as it allows hospitals to cont ract for a reservation of rights to recover from tortfeasors the differential between the negotiated and the usual and customary rates for emergency room services provided. 7

7 In so concluding, we are not called to determine whether or to what extent a hospital is limited in the amount it asserts to be its “customary rates.” (Cf. Howell , supra ,21 IV Whether the Dameron/Kaiser Contract Preserved Dameron’s Right to Recover its C ustomary Emergency Room Rates from Third

- p arty Tortfeasors Having concluded Dameron had the prerogative under Parnell , supra, 35 Cal.4th
595 to enter into a contract to preserve its billing rights against third party tortfeasors liable for injuries to its emergency room patients, we consider whether the Dameron/Kaiser contract actually preserved such rights. Dameron contends its contract with Kaiser suffices to allow it to pursue its customary billing rate from third party tortfeasors who injure Kaiser

- co vered patients. In evaluating Dameron’s claim, we apply well

- established principles governing review of contractual agreements. “The ordinary rules of contract interpretation apply equally to contracts of insurance. ( Palmer v. Truck Ins. Exchange (1999 ) 21 Cal.4th 1109, 1115.) The mutual intention of the contracting parties at the time the contract was formed governs. (Civ. Code, § 1636; Palmer, supra , at p. 1115.) We ascertain that intention solely from the written contract if possible, but also con sider the circumstances under which the contract was made and the matter to which it relates. (Civ. Code, §§ 1639, 1647.) We consider the contract as a whole and interpret the language in context, rather than interpret a provision in isolation. ( Id ., § 1641.) We interpret words in accordance with their ordinary and popular sense, unless the words are used in a technical sense or a special meaning is given to them by usage. ( Id ., § 1644.) If contractual language is clear and explicit and does not invol ve an absurdity, the plain meaning governs. ( Id ., § 1638.)” ( American Alternative Ins. Corp. v. Superior Court (2006) 135 Cal.App.4th 1239, 1245.)

52 Cal.4th at p. 551 [limiting economic damages to “ any reasonable charg es for treatment the injured person has paid or, having incurred, still owes the medical provider are recoverable as economic damages ”], italics added.)22

Here, the Dameron/Kaiser contract was entered into in 199 5 , a decade before the California Supreme Court is sued its decision in Parnell, supra, 35 Cal.4th 595

. The contract does not expressly reserve to Dameron a right to recover its customary billing rates for emergency room services from anyone. The Dameron/Kaiser contract does not mention HLA liens, third party tortfeasors, or liability insurers for third party tortfeasors. Instead, the contract sets forth the reciprocal obligations of Dameron to provide emergency medical services and Kaiser to pay negotiated rates for those services. 8
Rather than reservi ng the right to recover the entirety of the customary charge from third party tortfeasors, the Dameron/Kaiser contract states payment of the negotiated rates constitutes payment in full. Exhibit A of the Dameron/Kaiser contract provides: “[Kaiser] will pa y [Dameron] for Covered Services the rates set forth in this Exhibit A, reduced by applicable Copayments . . . . [Dameron] will accept such amounts as payment in full for Covered Services , irrespective of the cost to [Dameron] of providing such services, or of [Dameron] ’s customary charges for such services.” ( Italics added.) This contract provision does not reserve to Dameron any right to recover additional payments from any other person or entity. Moreover, it imposes on Kaiser no obligation to assis t or take any other action to help Dameron recover its customary charges from any third party tortfeasor or liability insurer. And, there is no mention of HLA liens. To escape this express agreement to accept the negotiated rate as “payment in full,” Dam eron looks to the “Member Billing” section of the contract. Specifically, Dameron points to language stating that “Hospital shall look solely to Kaiser Permanente

8 In the copy of the Dameron/Kaiser contract filed in the trial court, the pages specifying the negotia ted billing rates are marked “with[h]eld as proprietary trade secret info.” Even so, the parties agree the contract supplied Kaiser with negotiated billing rates for emergency room services that were less than Dameron’s customary rates for the same servic es.23

( or another responsible payer ) for compensation for Hospital Services rendered to
Members un der this Agreement.” (Italics added.) Dameron argues the italicized language renders this contract provision sufficiently ambiguous to allow extrinsic evidence to prove that “another responsible payer” includes tortfeasors and their liability insurers. A contract is ambiguous when it contains language that is reasonably susceptible to more than one meaning. ( MacKinnon v. Truck Ins. Exchange (2003) 31 Cal.4th 635, 648.) For several reasons, the contract’s reference to “another responsible payer” cannot reasonably be construed to refer to third party tortfeasors or their liability insurers. First, the reference to another responsible payer is qualified by the restriction that Dameron is limited to “compensation for Hospital Services rendered to Members under this Agreement. ” (Italics added.) The purpose of the Dameron/Kaiser contract is to agree upon negotiated billing rates and to insulate patients covered by Kaiser from charges beyond their individual copayment responsibilities. Under this agreemen t, there is no mention of customary billing rates or HLA liens. Second, the paragraphs immediately following language cited by Dameron serve to limit Dameron’s “claims for compensation” to copayments, services after coverage is exhausted or disallowed by Kaiser, instances in which the patient turns out to have no Kaiser coverage at all, and “regular Medicare.” Even if the meaning of “another responsible payer” were ambiguous, these paragraphs preclude any interpretation of the phrase to include third par ty tortfeasors or their liability insurers. Third, any interpretation of “another responsible payer” as including third party tortfeasors would create a conflict with the portion of the Dameron/Kaiser contract in
which Dameron has agreed to accept the ne gotiated rates “ as payment in full for Covered
Services , irrespective of the cost to [Dameron] of providing such services.” (Italics added.) We reject this interpretation as introducing an unnecessary internal inconsistency
into the Dameron/Kaiser contra ct. “It is a cardinal rule of construction that a contract is24

to be construed as a whole, effecting harmony among and giving meaning to all the parts thereof. (Civ. Code, § 1641.)” ( People ex rel. Dept. of Parks and Recreation v. West

- A

Rama, Inc . (1973 ) 35 Cal.App.3d 786, 793.) Fourth, Dameron’s assertion of the ability to collect customary rates from other parties would have the effect of imposing new duties on Kaiser that are not otherwise spelled out in the contract. In its briefing, Dameron contend s we should accept a history of cooperation between Dameron and Kaiser in pursuing additional payments from third party tortfeasors. In other words, Dameron argues Kaiser has a contractual duty to assist in recovering the customary billing rates for its p atients from others. Crediting this argument would mean Dameron could sue Kaiser for breach of contract if that health care service plan did not help pursue Dameron’s HLA liens. The Dameron/Kaiser contract spells out no such obligation for Kaiser.
The Dameron/Kaiser contract’s silence as to any obligation to assist in collection from third party tortfeasors does not allow us to graft a new obligation into the agreement. Indeed, the contract itself provides that “[a]ny other agreements, promises, negoti ations, or representations relating to the subject matter of this Agreement . . . not expressly set forth herein are of no force and effect.” “Courts will not add a term about
which a contract is silent. ( Moss Dev. Co. v. Geary (1974) 41 Cal.App.3d 1, 9. )” ( Levi Strauss & Co. v. Aetna Casualty & Surety Co. (1986) 184 Cal.App.3d 1479, 1486 dismissed, remanded and ordered published sub nom. Levi Strauss and Co. v. Aetna Cas.
and Sur. Co . (1987) [ 237 Cal.Rptr. 455].) Instead, “[a] contract extends only to those things which it appears the parties intended to contract. Our function is to determine what, in terms and substance, is contained in the contract, not to insert what has been omitted. We do not have the power to create for the parties a contract th at they did not make and cannot insert language that one party now wishes were there.” ( Vons Companies, Inc. v. United States Fire Ins. Co . (2000) 78 Cal.App.4th 52, 58

- 59.)25

Dameron correctly points out that “[n]either law nor equity requires that every

t erm and condition be set forth in a contract.” ( Frankel v. Board of Dental Examiners (1996) 46 Cal.App.4th 534, 545.) Thus, “usual and reasonable terms found in similar contracts may be considered, unexpressed provisions of the contract may be inferred
f rom the writing, external facts may be relied upon, and custom and usage may be resorted to in an effort to supply a deficiency if it does not alter or vary the terms of the agreement.” ( Ibid. ) However, supplying implied terms to give effect to the expre ssed intent of the contract does not allow us to impose new duties and obligations to which the parties never agreed. “[C]ourts cannot make better agreements for parties than they
themselves have been satisfied to enter into or rewrite contracts because t hey operate harshly or inequitably. It is not enough to say that without the proposed implied covenant, the contract would be improvident or unwise or would operate unjustly. Parties have the right to make such agreements. The law refuses to read into c ontracts anything by way of implication except upon grounds of obvious necessity.” ( Ibid. ) Although Parnell

, supra, 35 Cal.4th 595 allows Dameron to contractually reserve the right to recover its customary billing rate for emergency room services for Kais er patients and caused by third party tortfeasors, Dameron has not done so in this case. 9

9 We note the summary judgments in favor of AAA and Allstate included claims pertaining to emergency room patients covered by health care service plans other than Kaiser. In the trial court, Dameron argued summary judgment could not be granted in fa vor of AAA and Allstate because their motions did not seek to dispose of all claims. The trial court granted summary judgment in favor of AAA and Allstate concluding claims involving Kaiser patients failed for lack of a debt underlying Dameron’s breach of contract claims. As to the non

- Kaiser patients, the trial court found Dameron had not amended the complaint to include these claims. In this appeal, Dameron does not contend the trial court erred in dismissing the claims based on these non

- Kaiser patien ts. Accordingly, we affirm also as to the trial court’s dismissal of claims premised on patients not covered by Kaiser.2 6 DISPOSITION The judgment is affirmed. Each party shall bear its own costs. (Cal. Rules of Court, rule 8.278(a)(1) & (2).)

Given our conclusion the judgments of dismissal were properly entered because the Dameron/Kaiser contracts did not reserve Dameron’s ri ghts to pursue customary billing amounts under HLA liens, we do not reach the question of whether Dameron timely filed its HLA liens in this case. Finally, we do not address whether the billing scheme asserted by Dameron to be its contractually reserved ri ght complies with California law by reimbursing Kaiser for the entirety of its payments if Dameron recovers the full customary billing rate from a third party tortfeasor or tortfeasor’s liability insurer.
