The Plan Attributes PUF (Plan-PUF) is one of the seven files that make up the Marketplace PUF. The Plan-PUF contains plan-level data on maximum out of pocket payments, deductibles, cost sharing, health savings account (HSA) eligibility, formulary ID, and other plan attributes. These data either originate from the Plans & Benefits template (i.e., template field), an Excel based form used by issuers to describe their plans in the QHP/SADP application process, or were generated by CCIIO for use in data processing (i.e., system-generated). The issuer can also import data created in other templates (e.g., Network IDs from the Network ID template, Service Area IDs from the Service Area template, and Formulary IDs from the Prescription Drug template) to use as allowable values for the applicable fields in the Plans & Benefits template, or enter these values manually.
