CMS Health Insurance Marketplace Data -- ACA Exchange Data

CMS' Center for Consumer Information & Insurance Oversight produces the Health Insurance Marketplace Public Use Files (Marketplace PUF) to increase transparency in the Health Insurance Marketplace and to support benefit and rate analysis.

The Marketplace, also known as the Affordable Insurance Exchange, is a key component of the Affordable Care Act (ACA).

CMS describes the Marketplace PUF data in the following way:

"The Marketplace PUF includes plan and issuer level information for certified Qualified Health Plans (QHPs) and stand-alone dental plans (SADPs) offered to individuals and small businesses through the Health Insurance Marketplace. The Marketplace PUF includes data from states participating in the Federally Facilitated Marketplaces (FFM), which include State Partnership Marketplaces (SPMs), and states whose State-based Marketplaces rely on the federal information technology platform for QHP eligibility and enrollment functionality. The Marketplace PUF does not contain any data on plans offered in states that established and operate their own Marketplace (State-based Marketplace) and do not rely on the federal platform for QHP eligibility and enrollment functionality, nor does it contain enrollment or claims data."

CMS offers a Factsheet and a FAQ and makes some overall and file-specific disclaimers: User Agreement, Machine-readable URL, and Transparency in Coverage.
