CMS-0057 API Gate - FHIR CapabilityStatement

It reads a FHIR CapabilityStatement as you edit it and reports, line by line, which of the four CMS-0057-F APIs it cannot yet stand as evidence for: Patient Access, Provider Access, Payer-to-Payer and Prior Authorization. 14 rules run, and a clock shows the days left to 1 January 2027.

Health IT engineers at Medicare Advantage organizations, state Medicaid and CHIP programs, and QHP issuers on the federal exchanges, plus the FHIR vendors building those servers. If your team owns the /metadata endpoint that CMS-0057-F will be judged on, this is your file.

A generic FHIR validator calls this file valid, because it checks the statement against the FHIR R4 schema, not against a federal rule. Schema-valid is the normal state of a payer server that is still missing Claim $submit, Group $export and $member-match. The rule, not the schema, is what CMS reads.

Every check is free and needs no licence key: all 14 rules, every finding, every file, no limit. The paid tier changes who holds the result, not how much you can see. $29 once exports the same audit as a dated Markdown and CSV gap report with one row per gap and its CMS-0057-F citation.

A payer interoperability readiness review from an interop consultancy is commonly quoted as a five-figure engagement. This extension does not replace that review; it removes the mechanical gaps before you pay for one, so the consultant reads the hard questions instead of your missing operations.
