On January 17, 2017, the Substance Abuse and Mental Health Services Administration (SAMHSA) finalized changes to the Confidentiality of Alcohol and Drug Abuse Patient Records Regulations, 42 CFR Part 2. Under these changes to the Part 2 regulations, CMS is now permitted to include substance use disorder claims data in the Research identifiable Files (RIFs).
CMS is pleased to announce improvements to the Master Beneficiary Summary File (MBSF) to include timely Medicare Advantage (Part C) enrollment information and Medicare Prescription Drug (Part D) enrollment information.
The Research, Statistics, Data & Systems page on the CMS website
contains a number of links to CMS statistical information. You will find
links to reports, publications, downloadable public use files, and
descriptions of data available.
