2019 Medicare Advantage (Part C) Encounter Data Now Available

CMS is pleased to announce the availability of updated 2019 Medicare Advantage (Part C) Encounter data. In June 2021, CMS released a “Preliminary” version of the 2019 Medicare Advantage (MA) Encounter RIFs to give researchers earlier access to Encounter data for this service year. The Preliminary 2019 RIF data was not fully mature because Medicare Advantage Organizations (MAOs) were still submitting encounter records for that service year to CMS.

2019 Medicaid and CHIP Data Now Available

CMS is pleased to announce that updated Medicaid T-MSIS Analytic Files (TAFs) for service year 2019 are now available. The TAF research files* contain data on Medicaid and Children's Health Insurance Program (CHIP) beneficiary demographics, program enrollment, service use, and payments. They are designed to meet the diverse research needs of the Medicaid and CHIP data user community. In December 2020, CMS made "preliminary" TAF enrollment and claims files for service year 2019 available to researchers.

Background:

This document describes the development and content of the TAF Annual Provider (APR) file. Based on data submitted to CMS from states through the T-MSIS process, the APR captures information about all providers authorized by a state to render services to Medicaid and CHIP beneficiaries at any point in the calendar year, as well as providers whose authorization is pending, denied, or terminated, regardless of whether or how often the providers billed the state for services.
