Hospitals report number of times the service or procedure, as defined by the HCPCS code, was performed.  CAHs report the number of times the revenue code visit was performed .  EXAMPLE:  A beneficiary received psychological testing (HCPCS code 96100 which is defined in one -hour intervals) for a total of three hours during one day.  The hospital reports revenue code 0918 in FL 42, HCPCS code 96100 in FL 44, and three units in FL 46.  The CAH would report revenue code 0918, leave HCPCS blanks, and report 1 unit in FL 46.   When reporting service units for HCPCS codes where the definition of the procedure does not include any reference to time (either in minutes , hours, or days), hospital outpatient departments do not bill for sessions of less than 45 minutes.  The A/B MAC (A) must return to the provider claims other than CAH claims that do not contain service units for each HCPCS code.   NOTE:  Service units do not need to be reported for drugs and biologicals (Revenue Code 0250).  Hospitals must retain documentation to support the medical necessity of each service provided, including beginning and ending time.   260.5 - Line Item Date of Service Reporting for Parti al Hospitalization  (Rev. 3019, Issued: 08- 07-14, Effective: 01- 01-12, ICD -10: Upon Implementation of ICD-  10, Implementation: 09- 08-14, ICD -10: Upon Implementation of ICD - 10)  Hospitals other than CAHs are required to report line item dates of service per  revenue code line for partial hospitalization claims.  Where services are provided on more than one day included in the billing period, the date of service must be identified.  Each service (revenue code) provided must be repeated on a separate line item along with the specific date the service was provided for every occurrence.  See examples below of reporting line item dates of service.  These examples are for group therapy services provided twice during a billing period.   For the claims, report as follows:    Revenue Code  HCPCS  Dates of Service  Units  Total Charges  0915  G0176  20090505  1 $80.00  0915  G0176  20090529  2 $160.00

For the claims, report as follows:    Revenue Code  HCPCS  Dates of Service  Units  Total Charges  0915  G0176  20090505  1 $80.00  0915  G0176  20090529  2 $160.00   NOTE : Information regarding the Form CMS -1450 form locators that correspond with these fields is found in Chapter 25 of this manual.  See the ASC X12 837 Institutional Claim Implementation Guide for related guidelines for the electronic claim.   The A/B MAC (A) must return to the hospital (RTP) claims where a line item date of service is not entered for each HCPCS code reported, or if the line item dates of service reported are outside of the statement covers period.  Line item date of service reporting is effective for claims with dates of service on or after June 5, 2000.   260.6 - Payment for Partial Hospitalization Services  (Rev. 3685, Issued: 12- 22-16, Effective: 01- 01-17, Implementation: 01- 03-17)  For hospital outpatient departments, the A/B MAC (A) makes payments on a reasonable cost basis until August 1, 2000 for partial hospitalization services.  The Part B deductible and coinsurance apply.  During the year, the A/B MAC (A) will make payment at an interim rate based on a percentage of the billed charges.  At the end of the year, the hospital will be paid at the reasonable cost incurred in furnishing partial hospitalization  services, based upon the Medicare cost report filed with the A/B MAC (A).  Beginning with services provided on or after August 1, 2000, payment is made under the hospital outpatient prospective payment system for partial hospitalization services.   For CAH s, payment is made on a reasonable cost basis regardless of the date of service.   In CY 2017, payment for non- excepted off -campus hospital -based PHPs will be made under the MPFS, paying the CMHC per diem rate for APC 5853, for providing 3 or more PHP servi ces per day.   The Part B deductible, if any, and coinsurance apply.   270 - Billing for Hospital Outpatient Services Furnished by Clinical Social Workers (CSW)  (Rev. 1, 10- 03-03) A3-3662
(Medicare Claims Processing Manual)
The Part B deductible, if any, and coinsurance apply.   270 - Billing for Hospital Outpatient Services Furnished by Clinical Social Workers (CSW)  (Rev. 1, 10- 03-03) A3-3662   Payment may be made for covered diagnostic and therapeutic services f urnished by CSWs in a hospital outpatient setting.  CSW services furnished under a partial hospitalization program are included in the partial hospitalization rate.  Other CSW services must be billed to the A/B MAC (B) on Form CMS -1500 or the electronic equivalent.    See chapters 13 and 15, of the Medicare Benefit Policy Manual, for a discussion of the coverage requirements for CSW.   270.1 - Fee Schedule to be Used for Payment for CSW Services  (Rev. 1, 10- 03-03)  The fee schedule for CSW services is set at 75 percent of the fee schedule for comparable services furnished by clinical psychologists, except for services under a CAH partial hospitalization program.  These are paid on a reasonable cost basis.   270.2 - Outpatient Mental Health Payment Limitation fo r CSW Services  (Rev. 1, 10- 03-03)  The CSW services are subject to the outpatient mental health services limitation in 1833 of the Act.  The imitation of 62.5 percent is applied to the lesser of the actual charge or fee schedule amount.  Diagnostic services are not subject to the limitation.   270.3 - Coinsurance and Deductible for CSW Services  (Rev. 1, 10- 03-03)  The annual Pa rt B deductible and the 20 percent coinsurance apply to CSW services.  280 - Hospital -Based Rural Health Clinics (RHCs) and Federally Qualified Health Centers (FQHCs) Billing for Non RHC/FQHC Services  (Rev. 3941; Issued: 12- 22-17; Effective: 01-  01-18; Imp lementation: 01 -02-18)  A-01-93, A -03-066  Hospitals sometimes operate hospital based RHCs or FQHCs.  Prior to implementation of outpatient PPS, hospital based RHCs/FQHCs were permitted to include both RHC/FQHC and non- RHC/FQHC services on the same claim, under the RHC/FQHC bill type, with appropriate revenue codes.
(Medicare Claims Processing Manual)
Beginning with the implementation of OPPS, non- RHC/FQHC services provided by the hospital based RHC/FQHC, including RHCs/FQHCs that are parts of CAHs or other exempted or excluded (from OPPS) hospitals, must be billed under the host hospitals provider number, using hospital billing procedures and bill types.  These services are not covered or paid as RHC/FQHC services but instead may be covered hospital outpatient services and paid under the ap plicable methodology for the hospital.   The RHC/FQHC services remain subject to the encounter rate payment methodology and are billed using the RHC/FQHC provider number, bill type and revenue codes. See the Medicare Benefit Policy Manual for a description of covered RHC/FQHC services.   See chapter 9, in this manual for billing instructions for provider based and independent RHC/FQHC services.   290 - Outpatient Observation Services  (Rev. 1, 10- 03-03) A3-3663, A3- 3112.8.D, A -01-91  290.1 - Observation Services Overview  (Rev. 1760, Issued:  06- 23-09; Effective Date:  07- 01-09; Implementation Date:  07 -06-09)  Observation care is a well -defined set of specific, clinically appropriate services, which include ongoing short term treatment, ass essment, and reassessment, that are furnished while a decision is being made regarding whether patients will require further treatment as hospital inpatients or if they are able to be discharged from the hospital. Observation services are commonly ordered for patients who present to the emergency department and who then require a significant period of treatment or monitoring in order to make a decision concerning their admission or discharge.  Observation services are covered only when provided by the order  of a physician or another individual authorized by State licensure law and hospital staff bylaws to admit patients to the hospital or to order outpatient services.
(Medicare Claims Processing Manual)
Observation services must also be reasonable and necessary to be covered by Medicare. In only rare and exceptional cases do reasonable and necessary outpatient observation services span more than 48 hours.  In the majority of cases, the decision whether to discharge a patient from the hospital following resolution of the reason for the observat ion care or to admit the patient as an inpatient can be made in less than 48 hours, usually in less than 24 hours.  290.2 - General Billing Requirements for Observation Services  (Rev. 787, Issued: 12- 16-05, Effective: 01- 01-06, Implementation: 01- 03-06)  290.2.1 - Revenue Code Reporting  (Rev. 1760, Issued:  06- 23-09; Effective Date:  07- 01-09; Implementation Date:  07 -06-09)  Hospitals are required to report observation charges under the following revenue codes:    Revenue Code  Subcategory  0760 General Classification category  0762 Observation Room   Other ancillary services performed while the patient receives observation services are reported using appropriate revenue codes and HCPCS codes as applicable.   290.2.2 - Reporting Hours of Observation  (Rev.  2234, Issued: 05- 27-11, Effective: 07- 01-11, Implementation: 07- 05-11)  Observation time begins at the clock time documented in the patients medical record, which coincides with the time that observation care is initiated in accordance with a physicians  order.  Hospitals should round to the nearest hour.  For example, a patient who began receiving observation services at 3:03 p.m. according to the nurses notes and was discharged to home at 9:45 p.m. when observation care and other outpatient services were completed, should have a 7 placed in the units field of the reported observation HCPCS code.
(Medicare Claims Processing Manual)
General standing orders for observation services following all outpatient surgery are not recognized.  Hospitals should not report as observation care, services that are part of another Part B service, such as postoperative monitoring during a standard recovery period (e.g., 4 -6 hours), which should be billed as recovery room services.  Similarly, in the case of patients who undergo diagnostic testing in a hospital outpatient department, routine preparation services furnished prior to the testing and recovery afterwards are included in the payments for those diagnostic services.  Observation services should not be billed concurrently with diagnostic or the rapeutic services for which active monitoring is a part of the procedure (e.g., colonoscopy, chemotherapy).  In situations where such a procedure interrupts observation services, hospitals may determine the most appropriate way to account for this time. Fo r example, a hospital may record for each period of observation services the beginning and ending times during the hospital outpatient encounter and add the length of time for the periods of observation services together to reach the total number of units reported on the claim for the hourly observation services HCPCS code G0378 (Hospital observation service, per hour).  A hospital may also deduct the average length of time of the interrupting procedure, from the total duration of time that the patient rece ives observation services.   Observation time ends when all medically necessary services related to observation care are completed.  For example, this could be before discharge when the need for observation has ended, but other medically necessary services not meeting the definition of observation care are provided (in which case, the additional medically necessary services would be billed separately or included as part of the emergency department or clinic visit).  Alternatively, the end time of observation  services may coincide with the time the patient is actually discharged from the hospital or admitted as an inpatient.   Observation time may include medically necessary services and follow -up care provided after the time that the physician writes the disch arge order, but before the patient is discharged.  However, reported observation time would not include the time patients remain in the hospital after treatment is finished for reasons such as waiting for transportation home.   If a period of observation spans more than 1 calendar day, all of the hours for the entire period of observation must be included on a single line and the date of service for that line is the date that observation care begins.
(Medicare Claims Processing Manual)
If a period of observation spans more than 1 calendar day, all of the hours for the entire period of observation must be included on a single line and the date of service for that line is the date that observation care begins.   290.3 - Reserved  (Rev. 1882, Issued:  12- 21-09; Effective  Date:  01 -01-10; Implementation Date:  01 -04-10)  290.4 - Billing and Payment for Observation Services Furnished Between January 1, 2006 and December 31, 2007  (Rev. 1445, Issued:  02- 08-08; Effective:  01- 01-08; Implementation:  03 -10-08)  290.4.1 - Billing and Payment for All Hospital Observation Services Furnished Between January 1, 2006 and December 31, 2007  (Rev. 1760, Issued:  06- 23-09; Effective Date:  07- 01-09; Implementation Date:  07 -06-09)  Since January 1, 2006, two G -codes have been used to rep ort observation services and direct referral for observation care.  For claims for dates of service January 1, 2006 through December 31, 2007, the Integrated Outpatient Code Editor (I/OCE) determines whether the observation care or direct referral services  are packaged or separately payable.  Thus, hospitals provide consistent coding and billing under all circumstances in which they deliver observation care.   Beginning January 1, 2006, hospitals should not report CPT codes 99217- 99220 or 99234- 99236 for obs ervation services.  In addition, the following HCPCS codes were discontinued as of January 1, 2006:  G0244 (Observation care by facility to patient), G0263 (Direct Admission with congestive heart failure, chest pain or asthma), and G0264 (Assessment other than congestive heart failure, chest pain, or asthma).   The three discontinued G -codes and the CPT codes that were no longer recognized were replaced by two new G -codes to be used by hospitals to report all observation services, whether separately payable or packaged, and direct referral for observation care, whether separately payable or packaged:    G0378-  Hospital observation service, per hour; and   G0379-  Direct admission of patient for hospital observation care.
(Medicare Claims Processing Manual)
 G0378-  Hospital observation service, per hour; and   G0379-  Direct admission of patient for hospital observation care.    The I/OCE determines whether observation services billed as units of G0378 are separately payable under APC 0339 (Observation) or whether payment for observation services will be packaged into the payment for other services provided by the hospital in the same encounter.  Therefore, hospitals should bill HCPCS code G0378 when observation services are ordered and provided to any patient regardless of the patients condition. The units of service should equal the number of hours the patient receives observation services.   Hospitals should report G0379 when observation services are the result of a direct referral for observation care without an associated emergency room visit, hospital outpatient clinic visit, critical care service, or hospital outpatient surgical procedure (status indicator T procedure) on the day of initiation of observation services.  Hospitals should only report HCPCS code G0379 when a patient is referred directly for observation care after being seen by a physician in the community (see 290.4.2 below)
(Medicare Claims Processing Manual)
Some non- repetitive OPPS se rvices provided on the same day by a hospital may be billed on different claims, provided that all charges associated with each procedure or service being reported are billed on the same claim with the HCPCS code which describes that service.  See chapter 1, section 50.2.2 of this manual.  It is vitally important that all of the charges that pertain to a non -repetitive, separately paid procedure or service be reported on the same claim with that procedure or service. It should also be emphasized that this relaxation of same day billing requirements for some non- repetitive services does not apply to non- repetitive services provided on the same day as either direct referral to observation care or observation services because the OCE claim -by-claim logic cannot  function properly unless all services related to the episode of observation care, including diagnostic tests, lab services, hospital clinic visits, emergency department visits, critical care services, and status indicator T procedures, are reported on the  same claim.  Additional guidance can be found in chapter 1, section 50.2.2 of this manual.  290.4.2 - Separate and Packaged Payment for Direct Referral for Observation Services Furnished Between January 1, 2006 and December 31, 2007  (Rev. 1760, Issued:  06- 23-09; Effective Date:  07- 01-09; Implementation Date:  07 -06-09)  In order to receive separate payment for a direct referral for observation care (APC 0604), the claim must show:   1. Both HCPCS codes G0378 (Hourly Observation) and G0379 (Direct Admit to Observation) with the same date of service;   2. That no services with a status indicator T or V or  Critical care (APC 0617) were provided on the same day of service as HCPCS code G0379; and   3. The observation care does not qualify for separate payment under APC 0339.   Only a direct referral for observation services billed on a 13X bill type may be considered for a separate APC payment.   Separate payment is not allowed for HCPCS code G0379, direct admission to observation care, when billed with the same date of service as a hospital clinic visit, emergency room visit, critical care service, or T status procedure.
(Medicare Claims Processing Manual)
Separate payment is not allowed for HCPCS code G0379, direct admission to observation care, when billed with the same date of service as a hospital clinic visit, emergency room visit, critical care service, or T status procedure.   If a bill for the direct referral for observation services does not meet the three requirements listed above, then payment for the direct referral service will be packaged into payments for other separately payable services provided to the beneficiary in the same encounter.   290.4.3 - Separate and Packaged Payment for Observation Services Furnished Between January 1, 2006 and December 31, 2007 (Rev. 1760, Issued:  06- 23-09; Effective Date:  07- 01-09; Implementation Date:  07 -06-09)  Separate payment may be made for observation services provided to a patient with congestive heart failure, chest pain, or asthma.  The list of ICD -9-CM diagnosis codes eligible for separate payment is reviewed annually.  Any changes in applicable ICD -9-CM diagnosis codes are included in the October quarterly update of the OPPS and also published in the annual OPPS Final Rule.  The list of qualifying ICD -9-CM diagnosis codes is also published on the OPPS Web page.   All of the following requirements must be met in order for a hospital to receive a separate APC payment for observation services through APC 0339:   1. Diagnosis Requirements   a. The beneficiary must have o ne of three medical conditions: congestive heart failure, chest pain, or asthma.   b. Qualifying ICD -9-CM diagnosis codes must be reported in Form Locator (FL) 76, Patient Reason for Visit, or FL 67, principal diagnosis, or both in order for the hospital to  receive separate payment for APC 0339. If a qualifying ICD -9-CM diagnosis code(s) is reported in the secondary diagnosis field, but is not reported in either the Patient Reason for Visit field (FL 76) or in the principal diagnosis field (FL 67), separate payment for APC 0339 is not allowed.  2. Observation Time   a. Observation time must be documented in the medical record.   b. Hospital billing for observation services begins at the clock time documented in the patients medical record, which coincides with the time that observation  services are initiated in accordance with a physicians order for observation services.
(Medicare Claims Processing Manual)
b. Hospital billing for observation services begins at the clock time documented in the patients medical record, which coincides with the time that observation  services are initiated in accordance with a physicians order for observation services.   c. A beneficiary's time receiving observation services (and hospital billing) ends when all clinical or medical interventions have been comp leted, including follow -up care furnished by hospital staff and physicians that may take place after a physician has ordered the patient be released or admitted as an inpatient.   d. The number of units reported with HCPCS code G0378 must equal or exceed 8 hours.  3. Additional Hospital Services   a. The claim for observation services must include one of the following services in addition to the reported observation services.  The additional services listed below must have a line item date of service on the s ame day or the day before the date reported for observation:    An emergency department visit (APC 0609, 0613, 0614, 0615, 0616) or   A clinic visit (APC 0604, 0605, 0606, 0607, 0608); or   Critical care (APC 0617); or   Direct referral for observation care reported with HCPCS code G0379 (APC 0604); must be reported on the same date of service as the date reported for observation services.   b. No procedure with a T status indicator can be reported on the same day or day before observation care is provided.  4. Physician Evaluation   a. The beneficiary must be in the care of a physician during the period of observation, as documented in the medical record by outpatient registration, discharge, and other appropriate progress notes that are timed, written, and sig ned by the physician.   b. The medical record must include documentation that the physician explicitly assessed patient risk to determine that the beneficiary would benefit from observation care.   Only observation services that are billed on a 13X bill type  may be considered for a separate APC payment.
(Medicare Claims Processing Manual)
Only observation services that are billed on a 13X bill type  may be considered for a separate APC payment.   Hospitals should bill all of the other services associated with the observation care, including direct referral for observation, hospital clinic visits, emergency room visits, critical care services, and T st atus procedures, on the same claim so that the claims  processing logic may appropriately determine the payment status (either packaged or separately payable) of HCPCS codes G0378 and G0379.  If a bill for observation care does not meet all of the requireme nts listed above, then payment for the observation care will be packaged into payments for other separately payable services provided to the beneficiary in the same encounter.   290.5 - Billing and Payment for Observation Services Furnished on or After Janu ary 1, 2008 (Rev. 1445, Issued:  02- 08-08; Effective:  01- 01-08; Implementation:  03 -10-08)  290.5.1 - Billing and Payment for Observation Services Furnished Between January 1, 2008 and December 31, 2015  (Rev. 3425, Issued: 12- 18-15, Effective: 01- 01-16, Implementation: 01 -04-16)
