Starting in 2008, some institutional files contained Medicare Provider Numbers with a “V” in the fifth position.  These provider numbers represent Veterans Administration (VA) Demonstration claims.  A full explanation is found in the CMS Internet Only Manuals, 100-04 Claims Processing Manual, Chapter 37 – Department of Veterans Affairs (VA) Claims Adjudication Services Project.

These VA records are found in the RIF and LDS versions of the MedPAR, Inpatient, and Outpatient files.

Recommendation:

ResDAC recommends excluding these claims from the utilization files because these records don’t represent all the services provided to Medicare beneficiaries at VA hospitals.
