FHIR stands for Fast Healthcare Interoperability Resources. It is a standard from HL7 for exchanging health information through modern web-based interfaces and structured resources.
FHIR and claims are not the same thing
FHIR can help systems exchange patient, coverage, clinical, and administrative data. The CMS-1500 remains a paper professional claim form, while the X12 837P is the standard electronic professional claim transaction used by payers.
Where FHIR may fit
Health plans, providers, EHRs, and applications may use FHIR for data access, prior authorization workflows, patient access, and interoperability. It can support billing processes, but it does not simply replace every claim format or payer requirement.
Billing reminder: Payer and program requirements vary. Confirm the current instructions for the payer receiving the claim.
