The Centers for Medicare & Medicaid Services (CMS) Center for Consumer Information & Insurance Oversight (CCIIO) publishes the Exchange PUFs (Public Use Files) in order to improve transparency and increase access to data on Qualified Health Plans (QHPs) and Stand-alone Dental Plans (SADPs) offered through the Exchange in the individual market and Small Business Health Options Program (SHOP). The PUFs include data from states with Federally-facilitated Exchanges (FFEs), which include states with State Partnership Exchanges (SPEs), and State-based Exchanges that rely on the federal information technology platform for QHP eligibility and enrollment functionality (SBE-FPs). The Exchange PUFs also include data on MultiState Plans (MSPs) and certified off-exchange SADPs. The PUFs do not include data from SBEs that do not rely on the federal platform for QHP eligibility and enrollment functionality.
The Plan ID Crosswalk PUF (CW-PUF) is one of the files that make up the Exchange PUFs. The purpose of the CW-PUF is to map QHPs and SADPs offered through the Exchanges during the previous plan year to plans that will be offered through the Exchanges in the current plan year. These data either originate from the Plan Crosswalk template (i.e., template field), an Excel-based form used by issuers to describe their plans in the QHP application process, or were generated by CCIIO for use in data processing (i.e., system-generated).
