FHIR API Integration
PNT Data Corp. provides managed FHIR R4 API integration, bridging legacy EDI infrastructure with the FHIR-based interoperability that CMS-0057-F requires.
How Post-n-Track Handles FHIR Integration
CMS-0057-F and other federal mandates require health plans and their trading partners to support FHIR R4 APIs for patient access, provider directory, and payer-to-payer data exchange. Most healthcare organizations have significant investments in legacy EDI infrastructure that cannot be replaced overnight, creating a mandate to support both old and new standards simultaneously.
Post-n-Track provides a managed FHIR bridge that translates between legacy EDI transactions and modern FHIR R4 APIs. We enable organizations to meet their CMS-0057-F FHIR obligations without replacing their existing EDI infrastructure: a managed translation layer that supports both standards simultaneously.
- CMS-0057-F compliance FHIR R4 obligations met through a managed bridge.
- EDI investments protected Existing infrastructure stays in place.
- Both standards at once A managed translation layer between legacy EDI and FHIR R4 APIs.
The API Is Not the Hard Part
FHIR R4 (Fast Healthcare Interoperability Resources) is a REST and JSON standard for healthcare data exchange, and it is the standard CMS-0057-F points at, with API compliance dates beginning January 1, 2027. FHIR programs rarely fail on API construction. They fail because the source data doesn't exist in a form the API can serve, or because identity and consent weren't decided before endpoints were written.
Data availability, before endpoints
Building a conformant FHIR endpoint is a known quantity. Populating it from systems that model the data differently, with the completeness the profile requires, is not.
Programs that begin with endpoint construction discover the data gap in testing, when it is expensive.
Identity and the X12 Path
Identity and Consent Constrain the Design
Who can call this, on whose behalf, with what consent, and how is that proven: these questions shape the API. Deciding them after the endpoints exist means rebuilding them. This is doubly true for CMS-0057-F's Provider Access API, where attribution (proving a treatment relationship) is the core problem.
FHIR Does Not Replace X12
The 837, 835, 270/271, and 278 remain the HIPAA standard transactions. FHIR is additive. For years both paths will exist and organizations will operate against whichever a given payer supports. PNT translates between X12 and FHIR in transit and retains nothing.
Frequently Asked Questions
Does FHIR replace X12 EDI?
No. The X12 transactions (837, 835, 270/271, 278) remain the HIPAA standard transactions. FHIR is additive, including under CMS-0057-F. Both paths will coexist for years and organizations will need to operate against whichever a given payer supports.
Why do FHIR API projects fail?
Rarely on endpoint construction, which is a known quantity. Usually because the source data doesn't exist in a form the API can serve at the completeness the profile requires, or because identity and consent decisions were deferred until after endpoints were written and then forced a rebuild.
When is the CMS-0057-F API deadline?
CMS-0057-F, the CMS Interoperability and Prior Authorization Final Rule, requires impacted payers to implement FHIR-based Patient Access, Provider Access, Payer-to-Payer, and Prior Authorization APIs. API compliance dates begin January 1, 2027.
