Health Insurance Exchange Public Use Files (Exchange PUFs)

Health Insurance Exchange Public Use Files (Exchange PUFs)

The Centers for Medicare & Medicaid Services (CMS) Center for Consumer Information and Insurance Oversight (CCIIO) is committed to increasing transparency in the Health Insurance Exchanges. While health plan information including benefits, copayments, premiums, and geographic coverage is publicly available on, CMS also publishes downloadable public use files (PUFs) so that researchers and other stakeholders can more easily access Exchange data.

The Health Insurance Exchange Public Use Files (Exchange PUFs) are available for plan years 2014 to 2024 to support timely benefit and rate analysis. For data on the most recent plan year, CMS will post updates to the 2024 Exchange PUFs to reflect the plan data that consumers will see when shopping for an Exchange Qualified Health Plan (QHP). Data for the 2024 Exchange PUFs were last imported to CMS systems by April 30, 2024. 

The Exchange PUFs include plan and issuer level information on certified Qualified Health Plans (QHPs) and stand-alone dental plans (SADPs) offered to individuals and small businesses through the Health Insurance Exchanges. The Exchange PUFs include data from states participating in the Federally Facilitated Exchanges (FFE) including states performing plan management functions, and states whose State-based Exchanges rely on the federal information technology platform for QHP eligibility and enrollment (SBE-FP). The PUFs also include data on Multi-State Plans (MSPs) and certified off-exchange SADPs. The Exchange PUFs generally exclude information from SBEs that do not rely on the federal platform for QHP eligibility and enrollment.

The Exchange PUFs consist of twelve separate files as described below:

  • Benefits and Cost Sharing PUF (BenCS-PUF) – Plan variant-level data on essential health benefits, coverage limits, and cost sharing.
  • Rate PUF (Rate-PUF) – Plan-level data on rates based on an eligible subscriber’s age, tobacco use, and geographic location; and family-tier rates.
  • Plan Attributes PUF (Plan-PUF) – Plan-level data on maximum out of pocket payments, deductibles, HSA eligibility, and other plan attributes.
  • Business Rules PUF (BR-PUF) – Plan-level data on rating business rules, such as maximum age for a dependent, and allowed dependent relationships.
  • Service Area PUF (SA-PUF) – Issuer-level data on geographic service areas including state, county, and zip code.
  • Network (Ntwrk-PUF) – Issuer-level data identifying provider network URLs.
  • Plan ID Crosswalk PUF (CW-PUF) – Plan-level data mapping plans offered in the previous plan year to plans offered in the current plan year.

  • Transparency in Coverage PUF (TC-PUF) – Issuer and plan-level claims, appeals, and active URL data. The PY2024 PUF contains data from PY2022 for issuers participating in the Exchanges in PY2022.
  • Quality PUF (Qual-PUF) – Quality ratings data for plans offered through the Federally-Facilitated Exchanges. The PY2017 PUF is found below. The PY2018 through PY2024 PUFs are found here.
  • Nationwide Quality Rating System PUF (NatQRS-PUF) – Quality ratings data for plans offered through Exchanges nationwide, including State Based Exchanges (SBE). The PY2020 through PY2024 PUFs are found here.
