The Centers for Medicare & Medicaid Services (CMS) launched a process that permits state access to Medicare Parts A, B, and D data in response to several state requests for claims information to improve how they manage care for dual eligible beneficiaries. Data that may be requested, subject to procedural limitations, are:
- Medicare Parts A and B claims and Part D prescription drug event data;
- Medicare Parts A, B, C, and D eligibility and enrollment data;
- Assessments data, including Minimum Data Set (MDS), Outcome and Assessment Information Set (OASIS), Swing Bed, and Inpatient Rehabilitation Facility Patient Assessment Instrument (IRF-PAI); and
- Medicare Provider and Analysis Review (MedPAR) and Medicaid Enrollee Supplemental File (MESF) data.
