For most Medicare and Medicaid files (all except Medicare PDE) researchers may apply for three different levels of data:
Level 1: The standard release, which contains enrollment and utilization information but omits geographic identifiers and masks provider identifiers, which should meet the needs of most users
Level 2: A geographic release, which adds beneficiary state, county and zip code to the above
Level 3: A provider release, which includes complete provider identifiers and geographic information for respondents and providers.
