EXPANDED MODIFIED MEDPAR FILE

The Medicare Provider Analysis and Review (MEDPAR) file contains records for 100 percent of Medicare beneficiaries using hospital inpatient services. The records are stripped of most data elements that will permit identification of beneficiaries. The hospital is identified by the six-position Medicare bill number. The file is available to persons qualifying under the terms of the routine use act as outlined in the December 24, 1984, Federal Register, and amended by the July 2, 1985 notice.

SIGNED DATA RELEASE AGREEMENT REQUIRED. FOR ALL FILES REQUIRING A SIGNED DATA RELEASE AGREEMENT, PLEASE WRITE OR CALL TO OBTAIN A BLANK AGREEMENT FORM BEFORE PLACING ORDER.

Two versions of this file are created each year. l. Notice of Proposed Ruling (NPRM) published in the Federal

Register, usually available by the end of May. This file is derived from the MEDPAR file with a cutoff of three months after the end of the fiscal year (December file).

2. Final Rule published in the Federal Register, usually available by the first week of September. This file is derived from the MEDPAR file with a cutoff of six months after the end of the fiscal year (March file).

The file specifications for the Expanded Modified MEDPAR File are as follows:

The categories were developed by a Yale University research team and revised by Health Services International, Inc. * Please note: For the purposes of IPPS regulation development, the Present on Admission (POA) indicator was not considered in the grouping process. The groupings in this file reflect the DRG into which the case is categorized without incorporating any POA indicators.

72 DRG Version 25 Description: Each DRG represents broad clinical categories that are based on body system involvement and disease etiology. Each category is similar in its use of diagnostic resources and is identified using specific guidelines. Each category must have been clinically consistent, had a sufficient number of patients, and covered the complete range of diagnoses represented in the ICD-9-CM, without overlap. The categories were developed by a Yale University research team and revised by Health Services International, Inc. * Please note: For the purposes of IPPS regulation development, the Present on Admission (POA) indicator was not considered in the grouping process. The groupings in this file reflect the DRG into which the case is categorized without incorporating any POA indicators. Coding Scheme: Three-position field nnn, where n is a number Original Source: Added to the record by the intermediary's GROUPER software, which translates variables such as age, sex, diagnosis and surgical codes into the single applicable DRG.
