Inpatient Rehabilitation Facility (IRF) Help Reference¶

The IRF PPS is used to reimburse inpatient rehabilitation facilities for Medicare Part A services.

[!NOTE] This content is sourced from the official CMS Web Pricer.

Actual geographic MSA¶

Actual Geographic Metropolitan Statistical Area (MSA), indicates where a provider is located. The Actual Geographic MSA is entered as a 4-digit value, that ranges from 0040-9965. In a rural area, the Actual Geographic MSA is entered as '00' followed by the 2-digit numeric state code. For example, Ohio with state code 36 would be entered as '0036'.

Add-on visit amount¶

The add-on amount to be applied to the earliest line item date with the corresponding revenue code.

Admit date¶

This field requires the date the patient was admitted to the facility (the ADMIT date in FL 12 of the UB 04).

AIDS Add-on Indicator¶

Flag indicating if an AIDS adjustment is applicable.

Average length of stay (LOS) case-mix group (CMG)¶

The average length of stay (LOS) represents the typical number of days of care a patient receives for a given case-mix group (CMG) tier. The LOS values for each CMG tier level are published in the IRF prospective payment system proposed and final rules each year. LOS values can be found in the IRF final rule in the Federal Register, searchable here: https://www.federalregister.gov/agencies/centers-for-medicare-medicaid-services

Bed size¶

The facility bed size is equal to the number of adult hospital beds and pediatric beds available to inpatient lodging. This field must be greater than zero.

Beneficiary CBSA¶

Enter the Core-Based Statistical Area code representing the beneficiary’s site of service, if services were provided in the home. This is the value code 61 amount from the claim.A residence can be an inpatient facility if an individual uses that facility as a place of residence. It is the level of care that is required and not the location where services are provided that determines payment. In other words, if an individual resides in a freestanding facility and requires routine home care, then claims are submitted for routine home care.

Budget neutral adjustment¶

The budget neutral adjustment, also known as the standard payment conversion factor, provides the basis for determining the CMG-based IRF Federal payment rates. It is a standardized payment amount that is based on average costs from a base period and also reflects the combined aggregate effects of the payment weights, various facility-level and case-level adjustments, and other policies. Details about how this figure is calculated can be found in the IRF Final Rule in the Federal Register, searchable here: https://www.federalregister.gov/agencies/centers-for-medicare-medicaid-services

Capital cost-to-charge ratio¶

The capital cost-to-charge ratio is derived from the latest cost report and corresponding charge data from the billing file.For hospitals for which the MAC is unable to compute a reasonable cost-to-charge ratio, it uses the appropriate statewide average cost-to-charge ratio calculated annually by CMS and published in the Federal Register. A provider may submit evidence to justify a capital cost-to-charge ratio that lies outside a 3 standard deviation band. The MAC uses the hospital's ratio rather than the statewide average if it agrees the hospital's rate is justified.

Capital exception payment¶

Exception payments are provided for hospitals with inordinately high levels of capital obligations. The capital exception payment rate is the per discharge exception payment to which a hospital is entitled.

Capital hospital-specific rate¶

The hospital-specific capital rate is the hospital's allowable adjusted base year inpatient capital costs per discharge. This must be present unless a "Y" is entered in the Capital Indirect Medical Education Ratio field; or a "08" is entered in the Provider type field; or a termination date is present in Termination Date field. This field is not used as of October 1, 2002.

Capital indirect medical¶

An adjustment is provided to the Federal rate for indirect costs of medical education of interns and residents. The capital indirect medical education ratio field is the ratio of interns and residents to the hospital's average daily census. It is calculated by dividing the hospital's full-time equivalent total of residents during the fiscal year by the hospital's total inpatient days. This field is relevant for IPPS hospitals and IRFs.

Capital new harmless ratio¶

The new capital hold harmless ratio is the ratio of the hospital's allowable inpatient costs for new capital to the hospital's total allowable inpatient capital costs. This field is updated annually.

Capital old harmless rate¶

The old capital hold harmless rate shows the hospital's allowable inpatient "old" capital costs per discharge incurred for assets acquired before December 31, 1990, for capital PPS.

Capital PPS pay code¶

The capital PPS payment code indicates the type of capital payment methodology for hospitals. "A" indicates hold harmless, cost payment for old capital. "B" indicates hold harmless, 100% federal rate. "C" indicates fully prospective blended rate.

Case mix group (CMG)¶

Medicare patients are assigned to case-mix groups (CMGs) based on the primary reason for intensive rehabilitation care (for example, a stroke or hip fracture), age, and level of motor and cognitive function.Medicare patients are assigned to case-mix groups (CMGs) based on the primary reason for intensive rehabilitation care (for example, a stroke or hip fracture), age, and level of motor and cognitive function. Within each of these CMGs, patients are further categorized into one of four tiers based on the presence of specific comorbidities that have been found to increase the cost of care. Each CMG tier has a specific weight that is used to adjust the base payment rate up or down, to reflect the costliness of patients in that CMG tier relative to the costliness of the average Medicare IRF patient. Patients with a length of stay less than 4 days are assigned to a single CMG regardless of diagnosis, age, level of function, or presence of comorbidities. For more information, see: http://medpac.gov/docs/default-source/payment-basics/medpac_payment_basics_19_irf_final_sec.pdfFor a master list of HIPPS codes: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/ProspMedicareFeeSvcPmtGen/HIPPSCodes

Case-mix-index¶

A hospital's case-mix-index (CMI) represents the average diagnosis-related group (DRG) relative weight for that hospital. It is calculated by summing the DRG weights for all Medicare discharges and dividing by the number of discharges. CMIs are calculated using both transfer-adjusted cases and unadjusted cases.

Change code for reclass¶

When this field is active, "Y" indicates that the provider's wage index location has been reclassified for the year. "N" indicates that the provider has not been reclassified for the year.

Core-based statistical area (CBSA)¶

A Core-Based Statistical Area (CBSA) is a geographic area defined by the Office of Management and Budget (OMB). The CBSA designation is used to adjust for geographic differences in wages.The term refers collectively to metropolitan and micropolitan statistical areas, which consist of one or more counties (or equivalents) anchored by an urban center of at least 10,000 people plus adjacent counties that are tied to the urban center.

Core-based statistical area / Geographic CBSA¶

A Core-Based Statistical Area (CBSA) is a labor market area definition adopted by CMS based on the delineations defined by the Office of Management and Budget (OMB). A hospital's geographic CBSA is based on its geographic location, irrespective of any reclassification.

Cost¶

The dollar amount determined by the Pricer to be the payment for the visits in each discipline if the claim is paid as a Low Utilization Payment Adjustment (LUPA).

Cost of living adjustment¶

The cost of living adjustment (COLA) factor accounts for a higher cost of living in Alaska and Hawaii. The COLA factor provided to facilities is published annually in the final rule for the prospective payment systems.

Cost-to-charge ratio¶

The cost-to-charge ratio is derived from the latest settled facility cost report and corresponding charge data from the billing file. It is calculated by dividing the Medicare operating costs by Medicare covered charges.Medicare operating costs can be obtained from the Medicare cost report form CMS-2552-96, Supplemental Worksheet D-1, Part II, Line 53. Medicare covered charges can be obtained from the MAC billing file, i.e., PS&R record. For hospitals for which the MAC is unable to compute a reasonable cost-to-charge ratio, they use the appropriate urban or rural statewide average cost-to-charge ratio calculated annually by CMS and published in the Federal Register. These average ratios are used to calculate cost outlier payments for those hospitals where computed cost-to-charge ratios are not within the limits published in the Federal Register. For IRF and LTCH PPS, a combined operating and capital cost-to-charge ratio is entered here.
