I. BACKGROUND

Until January of 2004, Huffaker worked for Pepperidge Farms, a subsidiary of the Campbell

Soup Company, as a manager of a Pepperidge Farms thrift store. Huffaker was covered under the

Campbell Soup Company’s Long Term Disability Benefits Plan (“the Plan”), for which MetLife

processes benefits claims. 

On January 21, 2004, Huffaker applied for short-term disability benefits after fracturing one

of her left ribs due to coughing. The Attending Physician Statement submitted in support of her

claim noted that she was capable of working eight hours a day, but unable to perform heavy lifting,

and could return to work on “full duty with no restrictions” on January 27, 2004. MetLife

tentatively approved Huffaker’s claim for short-term disability benefits. 

On February 24, 2004, Huffaker consulted Dr. Charles Bozeman, a primary care physician,

after aggravating her rib injury. Dr. Bozeman prepared an Attending Physician Statement indicating

a primary diagnosis of a fractured rib and secondary diagnoses of bronchitis and fibromyalgia, noting

that Huffaker was “able to perform most of her job part of the time,” but was still recovering from

a fractured rib. During an office visit one month later, Dr. Bozeman noted that Huffaker’s pain had

worsened to the point that “[t]here is really hardly any place that she doesn’t hurt,” and diagnosed

Huffaker with fibromyalgia, hypertension under good control, hyperlipidemia, arthritis, myalgias,

and an elevated level of creatine phosphokinase (“CPK”). He directed that she see a neurologist, a

doctor of physical medicine, as well as a rheumatologist. 

Dr. Darrell Thomas, a neurologist, examined Huffaker, and found that she was “in no

apparent distress,” and felt that she “did not have fibromyalgia.” A doctor of physical medicine and

rehabilitation found that she had generalized muscle pain, “a constellation of symptoms not clearly
-3-

identified” and “not entirely consistent with a diagnosis of fibromyalgia,” and that her “elevated CPK

is suspicious for an underlying myopathic or metabolic process.” A cardiologist examined Huffaker,

and noted that he was “actually not sure what is going on with this lady. It seems like it is a little

more than fibromyalgia. [Fibromyalgia] should not cause abnormal CPK levels.” He further noted

that she “has some of the features of fibromyalgia,” but needed “a full evaluation by a

rheumatolog[ist] and neurolog[ist] to see if we are not missing something.” And a rheumatologist

examined Huffaker and found “no evidence of inflammatory arthropy or neurological focol or motor

deficits,” “a few tender points that suggest a myofascial component of her symptoms,” and that “the

most likely diagnosis” was fibromyalgia or chronic fatigue syndrome, but he “would like to obtain

additional records and additional laboratory tests.” 

On June 1, 2004, MetLife arranged for a medical review of Huffaker’s file by Dr. Tracey

Schmidt, a physician board-certified in internal medicine and rheumatology, who recommended

extending Huffaker’s disability status pending consideration of further records and test results. In

response to Dr. Schmidt’s request for information, Dr.Bozeman repeated his opinion that Huffaker's

pain was due to fibromyalgia. The neurologist repeated his prior appraisal of Huffaker as “a

well-nourished individual in no apparent distress.” The doctor of physical medicine submitted MRI

results indicating the presence of some disc bulging and degenerative changes, and repeated her

impression of “generalized body pain” with unclear etiology. And the cardiologist remarked that he

was “certainly not sure what exactly is causing all [of Huffaker's] ills,” and that Huffaker’s condition

“fits along the line of fibromyalgia and chronic fatigue syndrome with some type of mood disorder.”

With her short-term disability benefits expiring on July 19, 2004, Huffaker submitted a longterm disability claim, complaining of chronic pain. Dr. Bozeman submitted an Attending Physician
-4-

Statement diagnosing Huffaker with fibromyalgia and myofascial pain, noting that Huffaker could

work one hour per day and had severe limitations in psychological functioning. MetLife again

referred her medical file to Dr. Schmidt for review, who recommended an independent medical

examination with a rheumatologist, and tentatively approved Huffaker’s claim with continued

benefits dependent upon the outcome of the independent medical examination.

In the interim, Huffaker submitted treatment notes from a “new patient consultation” with

a rheumatologist, Dr. Kenny Sizemore, who diagnosed Huffaker’s condition as “probable

fibromyalgia,” noting that she was “so tender diffusely, Ithink even control points are positive.” He

noted, however, that “it was impossible to determine accurately” whether Huffaker was “seeking

some type of ‘secondary gain,’” and that he believed Huffaker could improve. He encouraged her

to follow up with a psychologist. 

On October 7, 2004, Huffaker underwent an independent medical examination with Dr.

Jeffrey Uzzle, a physician specializing in orthopedic medicine. Dr. Uzzle’s physical examination

found as normal Huffaker’s: gait pattern; posture; spinal alignment; muscle tone in her upper and

lower extremities; range of motion in her shoulders, elbows, wrists, and hands; and her ability to

walk on her heels and toes and tandem walk. He found her cervical, thoracic, and lumbosacral range

of motion normal and without pain. Dr. Uzzle noted that she described “several episodes that sound

psychological in nature.” After reviewing her medical records, Dr. Uzzle noted that Huffaker “has

been thoroughly evaluated from the standpoint of multiple different specialties and in the end there

has been no specific objective and verifiable anatomic problem to explain her varied

symptomatology.” He characterized Huffaker’s case as a “diagnostic dilemma” and expressed

concern that her pain disorder was largely psychologically based. He stated that he could not
-5-

ascertain why Huffaker stopped working and could “find no objective basis why she cannot return

to her work . . . assuming she is psychologically capable.” Huffaker later contested the validity of

the Dr. Uzzle’s findings–alleging that the examination consisted only of Dr. Uzzle’s request that she

walk on her toes and heels and touch her finger to her nose–but MetLife did not investigate the

allegations. 

On December 22, 2004, MetLife denied Huffaker’s claim, citing the findings of Dr. Uzzle.

Huffaker appealed on December 27, 2004, and submitted treatment notes from a psychiatrist, who

noted that Huffaker complained of depression, but did not assign any cognitive or functional

limitations to her condition. Dr. Bozeman submitted an updated Attending Physician Statement with

treatment notes, now opining that Huffaker could work a total of zero hours per day on account of

fibromyalgia and chronic myofascial pain syndrome. But he also noted that Huffakerstated that she

could consider trying to work, and he directed that she return to work for three hours per day, three

days a week, for the next three weeks, and to follow up with him in order to determine whether she

could further increase her hours. Huffaker also submitted a letter from her physical therapist, who

rated Huffaker’s pain as severe and consistent with fibromyalgia, and noted that she could not

reasonably be expected to attend a forty-hour work week. 

In response, MetLife sent Huffaker’s medical file to two physicians for independent file

reviews. Dr. Annette DeSantis, a physical medicine and rehabilitation specialist, conducted the first

review and concluded that there was no “medical documentation to substantiate functional

limitations that would preclude” Huffaker’s “ability to perform the material duties” of her job. Dr.

DeSantis noted that Huffaker “had extensive testing done, much of which was negative.” While

acknowledging that Huffaker had “some mildly positive tests,” Dr. DeSantis reiterated that she could
-6-

find no “actual physical medical condition that would keep [Huffaker] from being able to physically

perform her job.”

Dr. Edward Ewald, a rheumatologist, conducted the second review of Huffaker’s file. He

noted that the medical documentation demonstrated “no evidence of any active synovitis,” and that

Huffaker had normal strength with “no substantial limitation of motion of her joints.” He noted that

the findings described in Dr. Bozeman’s reports “are consistent with but not diagnostic of

fibromyalgia[,] since this is basically a diagnosis of exclusion.” He stated he could “find no

objective evidence in any of these records to substantiate functional limitations that would preclude

her ability to perform in material duties of her medium exertion level job. However, it is clear that

she does have persistent subjective complaints of muscle pains and joint pains.” 

On February 10, 2005, MetLife denied Huffaker’s appeal, citing the findings of Huffaker’s

physicians and the independent medical reviewers. Huffaker hired an attorney, who then sought to

submit several hundred pages of additional information for consideration. MetLife advised that it

would not consider the supplemental documentation, given that it had alreadymade a final decision.

Huffaker filed a lawsuit in federal court seeking review of Metlife’s decision. On August

2, 2006, the district court denied Huffaker’s motion to permit discovery. On March 8, 2007, the

district court issued an opinion granting MetLife’s motion for judgment on the administrative record.

Huffaker v. Metropolitan Life Ins. Co., No. 3:05-CV-527, 2007 WL 760439 (E.D. Tenn. March 8,

2007). 

II. ANALYSIS

A. Standard of Review 

We review the district court’s grant of MetLife’s motion for judgment on the administrative
Under the terms of the Plan, the administrator “shall have the complete authority, in its 1

sole and absolute discretion, to administer, apply and interpret the Plan (and any related

documents and underlying policies) and to decide all matters arising in connection with the

operation or administration of the Plan.” 

-7-

record de novo, Wilkins v. Baptist Healthcare Sys. Inc., 150 F.3d 609, 613 (6th Cir. 1998), applying

the same standard of review of a plan administrator's action as the district court applies. Moore v.

Lafayette Life Ins. Co., 458 F.3d 416, 427 (6th Cir. 2006). We employ an arbitrary and capricious

standard to review MetLife’s decision to deny long-term disability benefits because the Plan confers

discretionary authority on the administrator to determine eligibility for benefits and to construe the

terms of the Plan. McDonald v. Western-Southern Life Ins. Co., 347 F.3d 161, 168 (6th Cir. 2003). 1

“Under this deferential standard, we will uphold a benefit determination if it is ‘rational in light of

the plan’s provisions.’” Gismondi v. United Techs. Corp., 408 F.3d 295, 298 (6th Cir. 2005)

(quoting Yeager v. Reliance Standard Life Ins. Co., 88 F.3d 376, 381 (6th Cir. 1996)). Thus, we will

uphold a decision “if it is the result of a deliberate principled reasoning process, and if it is supported

by substantial evidence.” Killian v. Healthsource Provident Adm’rs, Inc., 152 F.3d 514, 520 (6th

Cir. 1998) (internal quotations and citation omitted).

The arbitrary and capricious standard, however, is not entirely without “teeth.” McDonald,

347 F.3d at 172. Oftentimes, a plan administrator operates under a potential conflict of interest

because it is both the decision-maker determining which claims are covered, and also the payor of

those claims. Calvert v. Firstar Finance, Inc., 409 F.3d 286, 292 (6th Cir. 2005). In such

circumstances, where “the potential for self-interested decision-making is evident,” we will take the

administrator’s conflict of interest into account as a factor in determining whether the administrator’s

decision was arbitrary and capricious. Univ. Hosps. of Cleveland v. Emerson Elec. Co., 202 F.3d
-8-

839, 846 n.4 (6th Cir. 2000).

“While several courts have altered the standard of review to something less deferential than

the arbitrary and capricious standard where a benefits administrator is operating under a conflict of

interest, this Court has not taken that approach.” Calvert, 409 F.3d at 293 (citation omitted). The

inherent “conflict of interest does not displace the arbitrary and capricious standard of review; rather,

it is a factor that we consider when determining whether the administrator’s decision to deny benefits

was arbitrary and capricious.” Evans v. Unum Provident Corp., 434 F.3d 866, 876 (6th Cir. 2006)

(citing Kalish v. Liberty Mut./Liberty Life Assurance Co. of Boston, 419 F.3d 501, 506 (6th Cir.

2005)). 

B. Plan’s Appeal Provision

We first consider Huffaker’s argument that MetLife should have considered evidence she

submitted to MetLife following its denial of her appeal on February 10, 2005. She contends that

MetLife acted arbitrarily in closing the record, given that the Plan “does not explicitly limit MetLife

to considering only one appeal.” 

Although Huffaker is correct that the Plan does not expressly limit MetLife to considering

one appeal, the Plan conversely does not allow a claimant to take an unlimited or even a specified

number of appeals. The Plan provides for “a review of claims denied in whole or in part.” Because

the Plan treats a claimant’s right to appeal as a singular noun (“a review of claims”), MetLife did not

act arbitrarily in interpreting the Plan to permit only one appeal. We find persuasive the Fifth

Circuit’s holding that “the complete description of the process for one appeal without mentioning

a second appeal clearly implies that only one appeal is allowed.” Hilton v. Ashland Oil Inc., No.

96-40100, 1996 WL 731358, at *8 (5th Cir. Nov. 11, 1996). 
-9-

MetLife’s correspondence with Huffaker is consistent with its contention that Huffaker was

entitled to onlyone appeal. In its initial denial letter, MetLife advised Huffaker that she could appeal

by filing a written request within 180 days, and that she should include “any additional comments,

documents, records or other information relating to your claim that you deem appropriate for us to

give your appeal proper consideration.” The denial letter goes on to state: “[i]n the event that your

appeal is denied in whole or in part, you will have the right to bring a civil action” under ERISA.

Thus, by the explicit terms of this correspondence, Huffaker was advised that she must submit all

evidence deemed relevant by her in her appeal of MetLife’s benefits determination. The

correspondence made clear that the next tier of review after her appeal was not a second internal

appeal for MetLife’s consideration, but an ERISA action in federal court. 

C. MetLife’s Eligibility Determination

1. Objective Evidence of Disability

We next consider Huffaker’s argument that MetLife’s denial of disability benefits was

arbitrary and capricious. MetLife contends that its denial was based on Huffaker’s failure to prove

her disabled status under the terms of the Plan, namely because she provided insufficient objective

evidence of disability. We first address whether the terms of the Plan allow MetLife to require that

Huffaker present objective evidence of her disabled status. We hold that it may.

The Plan provides that a beneficiary will receive disability benefits once the beneficiary is

disabled as defined by the Plan, after the completion of an elimination period. The Plan defines

“disabled” as follows:

Disabled or Disability: You are Disabled if, due to sickness or pregnancy or

accidental injury for which you are receiving Appropriate Care and Treatment from

a Doctor on a continuing basis:
-10-

During the first 24 months that benefits under this Plan are paid to

you, you are unable to perform each of the material duties of your

Occupation.

After benefits under this Plan are paid to you for 24 months, you are

unable to engage in any business or occupation or to perform any

work for compensation, gain or profit for which you are reasonably

fitted by your education, training, background, or experience.

This Court has previously held that a disability benefits plan employing similar eligibility

requirements could require a claimant to provide objective evidence of disability. In Cooper v. Life

Ins. Co. of N. America, we held that “[r]equiring a claimant to provide objective medical evidence

of disability is not irrational or unreasonable.” Cooper v. Life Ins. Co. of N. America, 486 F.3d 157,

166 (6th Cir. 2007) (citing Spangler v. Lockheed Martin Energy Sys., Inc., 313 F.3d 356, 361 (6th

Cir. 2002)). The definition of “disability” at issue in Cooper required that the claimant prove

inability to perform “all the material duties of his or her Regular Occupation,” id. at 159-60, and did

not explicitly require the claimant to provide objective evidence of disability. We found the

administrator’s objective-evidence-of-disability requirement reasonable, explaining that “[o]bjective

medical documentation of [the claimant’s] functional capacity would have assisted [the

administrator] in determining whether [the claimant] was capable of performing ‘all the material

duties of her Regular Occupation,’ as required by the [long-term disability plan]’s definition of

disability.” Id. at 166. 

Here, Huffaker must similarly prove she is “unable to perform each of the material duties of

[her] Occupation” to satisfy the Plan’s definition of “disability.” As in Cooper, MetLife could

reasonably interpret the Plan’s language to require objective evidence of disability. See also Michele

v. NCR Corp., No. 94-3518, 1995 WL 296331, at *3 (6th Cir. May 15, 1995) (holding that the

administrator did not act arbitrarily or capriciously in denying long-term disability benefits for
The Seventh Circuit has aptly described the difficulties in diagnosing fibromyalgia: 2

[F]ibromyalgia, also known as fibrositis[,] is a common, but elusive and

mysterious, disease, much like chronic fatigue syndrome, with which it shares a

number of features. Its cause or causes are unknown, there is no cure, and, of

greatest importance to disability law, its symptoms are entirely subjective. There are

no laboratory tests for the presence or severity of fibromyalgia. The principal

symptoms are “pain all over,” fatigue, disturbed sleep, stiffness, and-the only

symptom that discriminates between it and other diseases of a rheumatic

character-multiple tender spots, more precisely 18 fixed locations on the body (and

the rule of thumb is that the patient must have at least 11 of them to be diagnosed as

having fibromyalgia) that when pressed firmly cause the patient to flinch. 

Hawkins v. First Union Corp. Long-Term Disability Plan, 326 F.3d 914, 916 (7th Cir. 2003)

(internal quotation marks, alterations, and citations omitted).

-11-

chronic fatigue syndrome where the plan requires proof of total disability from “a bodily injury or

disease”; and the claimant failed to present sufficient objective medical evidence of total disability).

A claimant could certainly find burdensome a requirement that she proffer objective evidence

of fibromyalgia itself, the symptoms of which are largely subjective. But objective evidence of 2

disability due to fibromyalgia can be furnished by a claimant without the same level of difficulty.

See Boardman v. Prudential Ins. Co., 337 F.3d 9, 16-17 n.5 (1st Cir. 2003) (“While the diagnos[is]

of . . . fibromyalgia may not lend [itself] to objective clinical findings, the physical limitations

imposed by the symptoms of such illness[] do lend themselves to objective analysis.”). One method

of objective proof of disability, for instance, is a functional capacity evaluation, a “reliable and

objective method of gauging” the extent one can complete work-related tasks. Cooper, 486 F.3d at

176 (Sutton, J., concurring in part, dissenting in part). In Johnson v. Metropolitan Life Ins. Co., 437

F.3d 809 (8th Cir. 2006), the Eighth Circuit held that a “plan administrator [can] require objective

evidence of a disability, even when the claimant’s alleged disability stem[s] from fibromyalgia, so

long as the administrator notified the claimant that her file lacked the required objective evidence.”
The medical evidence from Dr. Bozeman consists of a medical information form 3

addressed to the Social Security Administration, dated March 22, 2005. The medical evidence

from Dr. Thomas consists of a medical information form supplied by Huffaker’s attorney, dated

June 6, 2005. The medical evidence from Anita Ferris consists of a medical information form

supplied by Huffaker’s attorney, dated June 8, 2005. 

-12-

Id. at 814 (citing Pralutsky v. Metropolitan Life Ins. Co., 435 F.3d 833, 838-40 (8th Cir. 2006)).

Here, MetLife notified Huffaker that her file lacked the required objective evidence in its December

22, 2004 letter denying benefits, which stated as its reason for denial: “There is no medical evidence

provided by the treating sources to suggest a significant functional impairment or support the severity

of this medical condition to prevent you from performing your job.” Thus, MetLife did not act

unreasonably in requiring objective evidence of disability. 

2. Dr. Bozeman

We now review whether MetLife’s eligibility determination was supported by the evidence.

Huffaker contends that she provided MetLife with objective evidence of disability, and refers to three

sources: Dr. Thomas, the neurologist; Dr. Bozeman, her family practitioner; and Anita Ferris, the

physical therapist. In her argument on appeal that she is disabled under the Plan, however, the

documentary evidence that Huffaker relies on from these sources consists of forms submitted to

MetLife after MetLife’s February 10, 2005 denial of her internal appeal. We decline to consider

3

this evidence, because in our review of MetLife’s decision, we are “strictly limited to a consideration

of the information actually considered by the administrator.” Killian v. Healthsource Provident

Admin., Inc., 152 F.3d 514, 522 (6th Cir. 1998). 

 MetLife argues that the evidence considered by MetLife prior to its denial of her internal

appeal on February 10, 2005, supports its finding that Huffaker was not disabled under the Plan.

MetLife argues that Dr. Thomas’s findings do not support a finding of disability, referring to Dr.
-13-

Thomas’s physical examination of Huffaker on May 18, 2004, in which she is described as “a wellnourished individual in no apparent distress.” Although Dr. Thomas’s treatment notes mention that

the purpose of the consultation was to address Huffaker’s complaints of muscle cramps and pain

described as “excruciating,” the medical documentation from Dr. Thomas under consideration by

MetLife supports of its finding that she was not disabled. 

MetLife explains that it failed to accord great weight to Dr. Bozeman’s opinion that Huffaker

was disabled because his opinion was “based on Huffaker’s self-reported complaints of pain, nothing

more.” MetLife contends that his opinion is not supported by a functional capacity evaluation, and

was contradicted by Dr. Bozeman’s findings that Huffaker’s muscle strength was normal in all

extremities and that she had full range of motion in all joints, and by the negative results of the

battery of tests that she underwent. MetLife did not discredit the findings of Anita Ferris, the

physical therapist, on appeal. 

In Yeager, we observed that “complaints of fatigue and joint pain” are “types of subjective

complaints [that] are easy to make, but almost impossible to refute.” Yeager v. Reliance Standard

Life Ins. Co., 88 F.3d 376, 382 (6th Cir. 1996) (holding that absent any “definite anatomic

explanation of [a claimant]’s symptoms,” an administrator’s decision to deny disability benefits due

to fibromyalgia was not arbitrary and capricious); cf. Cooper, 486 F.3d at 174 (Sutton, J., concurring

in part, dissenting in part) (“[S]ubjective complaints of back pain by themselves do not compel an

administrator to grant disability benefits”). MetLife did not arbitrarily refuse to credit Dr.

Bozeman’s findings given the inconsistency between Huffaker’s subjective complaints of pain and

Dr. Bozeman’s findings of normal muscle strength and range of motion. 
-14-

3. Dr. Uzzle 

Huffaker next argues that MetLife erred in its reliance on the independent medical

examination of Dr. Uzzle. As her first reason, Huffaker argues that Dr. Uzzle, a doctor of orthopedic

medicine, is unqualified to diagnosis fibromyalgia. She argues that a rheumatologist should instead

have conducted the examination, because fibromyalgia is a rheumatological condition. But Huffaker

cites no factual or legal authority for the proposition that only a rheumatologist may diagnose

fibromyalgia. Her insistence on such a rule is inconsistent with her demand that great weight be

given to the opinions of Dr. Thomas, a neurologist; Dr. Bozeman, a family practitioner; and her

physical therapist, a non-physician. In any event, MetLife did in fact rely on the medical opinion of

a rheumatologist, Dr. Ewald, who reviewed Huffaker’s medical file. 

Huffaker next challenges Dr. Uzzle’s credibility by arguing that he failed to address whether

she had fibromyalgia. Our review of the content of Dr. Uzzle’s report, however, does not lead us

to this conclusion. His report noted that he reviewed records from Dr. Bozeman and others, and that

“[Huffaker] is at a point one would characterize as a diagnostic dilemma.” He specifically noted that

“[f]ibromyalgia has been considered,” and concluded from his review of Huffaker’s medical records

that she “has been thoroughly evaluated from the standpoint of multiple different specialties and in

the end there has been no specific objective and verifiable anatomic problem to explain her varied

symptomatology.” And he diagnosed Huffaker with “[c]hronic pain disorder.” The critical question

for purposes of Huffaker’s eligibility for disability benefits is not whethershe does or does not have

fibromyalgia, but whether she is disabled under the plan. Dr. Uzzle’s conclusion after conducting

a physical examination was that he could “find no objective basis why she cannot return to her work

as a thrift store outlet manager at this point assuming she is psychologically capable of doing this.”
-15-

Huffaker then argues that MetLife failed to investigate her allegation that Dr. Uzzle did not

examine her. But two physician file-reviewers, Drs. Ewald and DeSantis, examined Huffaker’s

medical file, which included Dr. Uzzle’s findings. Their review of Dr. Uzzle’s findings indicates

no basis for determining them unreliable. So even if MetLife did have a duty to investigate

Huffaker’s allegation, that duty would have been satisfied by the file review undertaken by Drs.

Ewald and DeSantis.

Finally, Huffaker argues that MetLife erred in failing to investigate Dr. Uzzle’s concern that

her complaints of pain might be psychosomatic. However, Huffaker never claimed a psychiatric

impairment during the administrative process, but rather claimed that her disability was due to

fibromyalgia. In any event, the administrative record includes treatment notes from a psychiatrist,

from as late as January 1, 2005. Although the psychiatrist prescribed the medication Cymbalta, he

did not diagnose any cognitive or functional limitations precluding her from working. 

Accordingly, we find that MetLife did not act arbitrarily or capriciously in relying on Dr.

Uzzle’s medical opinion as a basis for the denial of benefits.

4. Drs. Ewald and DeSantis 

Huffaker next argues that MetLife erred in relying on the opinions of Drs. Ewald and

DeSantis because reliance on non-examining medical sources is “disfavored,” and they ignored

functional limitations diagnosed by Dr. Bozeman. But it is well-established that MetLife need not

necessarily defer to the opinions of treating physicians. See Black & Decker Disability Plan v. Nord,

538 U.S. 822, 834 (2003). We have held that “[g]enerally, when a plan administrator chooses to rely

upon the medical opinion of one doctor over that of another . . . the plan administrator's decision

cannot be said to have been arbitrary and capricious.” McDonald v. W.-S. Life Ins. Co., 347 F.3d
-16-

161, 169 (6th Cir. 2003). And we observed in Calvert v. Firstar Finance, Inc., 409 F.3d 286, 295

(6th Cir. 2005), that “reliance on a file review does not, standing alone, require the conclusion that

[the administrator] acted improperly.” Thus, we “find nothing inherently objectionable about a file

review by a qualified physician in the context of a benefits determination.” Id. at 296.

Although “the failure to conduct a physical examination–especially where the right to do so

is specifically reserved in the plan–may, in some cases, raise questions about the thoroughness and

accuracy of the benefits determination,” id. at 295, this case does not present such an instance. Here,

MetLife obtained an independent medical examination, namely that of Dr. Uzzle. Dr. Uzzle’s

examination of Huffaker, however, was unfavorable to her disability claim. He personally examined

Huffaker and determined that she was not disabled, noting the absence of “specific objective and

verifiable anatomic problem to explain her varied symptomatology.” 

Our review of Drs. Ewald and DeSantis’s reports indicates that they reviewed the findings

of Dr. Bozeman, and each found that Huffaker’s medical record did not show the existence of a

functional limitation that would prevent Huffaker from doing her job. Dr. DeSantis’s report

mentions that she could find no "actual physical medical condition that would keep [Huffaker] from

being able to physically perform her job." Dr. Ewald concludes in his report that he could "find no

objective evidence in any of these records to substantiate functional limitations that would preclude

her ability to perform in material duties of her medium exertion level job.” Because MetLife validly

exercised its right to rely on the opinions of physicians other than the treating physician, see

McDonald, 347 F.3d at 169, we find Huffaker’s claim of error with respect to Drs. Ewald and

DeSantis without merit. 
-17-

D. Discovery Motion

Huffaker argues that the district court erred in denying her motion for discovery beyond the

administrative record for the purpose of showing a procedural violation. We review the district

court’s decisions on discovery matters for an abuse of discretion. Green v. Nevers, 196 F.3d 627,

632 (6th Cir. 1999).

In the proceedings below, Huffaker filed a motion to adjust the scheduling order to allow her

to take discovery. She sought discovery for the purpose of seeking information about the physicians

who evaluated her claim relevant to the issues of due process and bias, including their employment

relationship with MetLife, their compensation, and the number of claims they reviewed for MetLife.

She supported her motion with information relating to three physician consultants not having

involvement in her claim. The district court denied the motion, upholding the magistrate judge’s

memorandum and order, which held that “[t]he mere fact that MetLife may have used three other

physicians numerous times in other cases simply does not demonstrate good cause to engage in

discovery with respect to the physicians who reviewed the plaintiff’s claim.” 

In an ERISA claim for benefits action, the district court’s review is generally “based solely

upon the administrative record.” Wilkins v. Baptist Healthcare Sys., Inc., 150 F.3d 609, 619 (6th Cir.

1998). Evidence outside the administrative record may be considered “if that evidence is offered in

support of a procedural challenge to the administrator’s decision, such as an alleged lack of due

process afforded by the administrator or alleged bias on its part.” Id. “This also means that any

prehearing discovery at the district court level should be limited to such procedural challenges.” Id.

A claimant cannot obtain discovery beyond the administrative record–even if limited to a

procedural challenge–merely by alleging a procedural violation. See Likas v. Life Ins. Co. of N.
This Court has described the policy reasons for the district court’s review of only within- 4

record evidence as follows:

A primary goal of ERISA was to provide a method for workers and beneficiaries

to resolve disputes over benefits inexpensively and expeditiously. Permitting or

requiring district courts to consider evidence from both parties that was not

presented to the plan administrator would seriously impair the achievement of that

goal. If district courts heard evidence not presented to plan administrators,

employees and their beneficiaries would receive less protection than Congress

intended.

‘throw open the doors of discovery’ in an ERISA case.”) (citations and quotation marks omitted).

Otherwise, the policy rationale for constrained district court review would be defeated.

In Putney v. Medical Mutual of Ohio, 111 Fed. App’x 803 (6th Cir. 2004), we determined

that a claimant must make a predicate showing with respect to an alleged procedural violation to be

granted further discovery. The claimant in Putney argued that the district court erred in denying

discovery on a procedural challenge to the denial of a disability benefits claim. However, the Putney

claimant “presented virtually no evidence of procedural violations,” “presented absolutely no

evidence of bias,” and there were no facts in the record “to support a claim that discovery might lead

to such evidence.” Id. at 807. We concluded that “mere allegation of bias is not sufficient to permit

discovery under Wilkins’ exception.” Id. Even though the claimant alleged that the administrator

“refused to permit him to submit information during his administrative appeal,” we found this also

to be a “mere allegation,” insufficient to require discovery. Id.

Here, Huffaker is like the Putney claimant. The only evidence offered in support of the

allegation of procedural error is that MetLife has a “habit” of repeatedly using the same consultants.

As MetLife notes, the evidence puts forward a “generalized claim of financial conflict of interest on

the part of MetLife and the independent physician consultants who reviewed” her medical file. The

consultants whom Huffaker alleges MetLife habitually use did not even review her medical file, so

the evidence does not support her suggestion that the independent physicians in this case took

adverse action regarding her disability claim. Huffaker presents no actual evidence of a procedural

violation as to the claim, and because “mere allegation of bias is not sufficient to permit discovery,”

Putney, 111 Fed. App’x at 807, the district court did not err in denying her discovery motion. 

III. CONCLUSION

For the reasons stated above, we AFFIRM the district court’s judgment on the administrative

record for MetLife, and AFFIRM the denial of Huffaker’s motion for discovery.
