Supporting the Centers for Medicare & Medicaid Services (CMS) Oversight of Access to Care in Medicaid

2016-2019, 2019-2024

Project Overview


To support the Centers for Medicare & Medicaid Services in the development and implementation of a comprehensive strategy for access to care in Medicaid.

Project Motivation

Using regulations, guidance, and data analysis, CMS is developing a multifaceted strategy to help ensure equitable access to health care for people enrolled in Medicaid and CHIP across all care delivery systems.

Prepared For

U.S. Department of Health and Human Services, Centers for Medicare & Medicaid Services, Center for Medicaid and CHIP Services

Over the course of two projects since 2016, Mathematica is supporting CMS’s efforts to ensure equitable access to health care services for the millions of people covered by Medicaid and CHIP.

The current project assists CMS in building a comprehensive access strategy and related tools based on policy analyses, data analyses, and stakeholder input. Examples of activities include:

  • Organizing and hosting stakeholder listening sessions
  • Conducting scans and analyses of existing access-related statutes, regulations, and data sources
  • Comparing Medicaid and Medicare payment rates
  • Creating reports on providers’ participation and beneficiary needs in Medicaid using data from the Transformed Medicaid Statistical Information System (T-MSIS) Analytic Files (TAF) and other available data sources
  • Supporting the release and analysis of public comments received for a CMS Request for Information (RFI) on access to coverage and care in Medicaid and CHIP


Project Impact

In 2022, the project team supported CMS in fielding a public Request for Information (RFI) and analyzing the comments submitted. Findings from the 2022 Medicaid and CHIP Access RFI have and will continue to inform updates to CMS regulations and guidance to state programs.
