The Network PUF (Ntwrk-PUF) is one of the seven files that make up the Marketplace PUF. The Ntwrk-PUF contains issuer-level data identifying provider network URLs. These data either originate from the Network ID 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).
