MEDICARE DISPROPORTIONATE PATIENT PERCENTAGE
 

 

 

Medicaid Day Fraction

 

Medicaid Eligible Days – In calculating the number of Medicaid days, the hospital must determine whether the patient was eligible for Medicaid under a State plan approved under Title XIX on the day of service.  If the patient was eligible, the day is included in the Medicare DSH adjustment calculation.

 

Medicaid days, for purposes of the Medicare DSH adjustment calculation, include all days during which a patient is eligible, under a State program approved under Title XIX, for Medicaid benefits even if Medicaid did not make payments (e.g. Unpaid Patient Days) for any services.

 

 

The usual day components reported by the hospital are the following:

Medicaid Eligible Days

Medicaid HMO Days

Home & Community Based Service (1915(c) Eligible Patient)

Medicaid Out-of-State Patient Days

Medicaid Waiver Days

 

However, Medicaid days also include, but are not limited to:

Days that are determined to be medically necessary but for which payment is denied by Medicaid because the provider did not bill timely

Days that are beyond the number of days for which a State will pay

Days that are utilized by a Medicaid beneficiary prior to an admission approval but for which a valid enrollment is determined within the prescribed period

Days for which payment is made by a third party

 

Medicare Day Fraction

 

The Medicare fraction is computed by dividing the number of patient days for patients who were entitled to both Medicare Part A benefits and SSI benefits by the total number of patient days for patients entitled to benefits under Medicare Part A.

 

Our services include a full analysis of the Medicare fraction and related SSI percentage components. This analysis would include the audit, verification, and identification of total patient days with both SSI and Medicare Part A coverage (the fraction numerator) and Total Medicare Days (the fraction denominator).

 

In order to calculate the numerator of the Medicare fraction, HCS obtains a data file from CMS which is based on information obtained from the Social Security Administration (SSA) that includes a list of eligible SSI recipients.  HCS then matches information from this CMS’s SSI file against CMS’s Medicare Part A entitlement information contained in the Medicare Provider Analysis and Review (MEDPAR) file to determine the number of Medicare/SSI days for a particular hospital in a particular federal fiscal year.  The fraction denominator of the fraction is calculated by CMS based on Medicare claims data.

 

Examples of Medicare/SSI days include but are not limited to the following patient day components:

Medicare/SSI patient days

Medicare HMO/SSI patient days

Detail testing and identification of SSI and SSA patient database information

SSI patient database omissions

Multiple identifiers to identify SSI recipients and to match MEDPAR data

 

Hospital Database Analysis

 

In order to fully account for all hospital DSH patient day information, a number of large databases will have to be analyzed, comparatively matched with other hospital database information sources, and interfaced with a number of governmental databases for  Medicare, Medicaid and Social Security Administration information.

 

HCS has developed a number of computer-based programs which are used to integrate the numerous sources of hospital and government information and patient databases.

 

Database Computer-Based Programs Included the following:

State plan Medicaid eligibility information programs

CMS Medicare eligibility information programs

Hospital information systems database programs

SSA and SSI database programs

MEDPAR database programs
