FHIR service
Data interoperability services focus on exchange across organizations rather than a single point-to-point connection: health information exchanges, payer-provider data sharing, public health reporting, research networks and national frameworks such as TEFCA. The hard problems here are less about APIs and more about identity, terminology, consent, provenance and governance.
| Scenario | What moves | Relevant standards |
|---|---|---|
| Payer to provider | Claims, encounter and clinical data for attributed patients | Da Vinci PDex, Bulk Data, CMS-0057-F Provider Access API |
| Payer to payer | Member history when a member changes plans | Da Vinci PDex payer-to-payer, CMS-0057-F |
| Prior authorization | Coverage requirements, documentation, decisions | Da Vinci CRD, DTR and PAS |
| HIE and network query | Patient records across many organizations | IHE profiles, C-CDA, FHIR APIs, TEFCA |
| Public health | Case reports, immunizations, lab reporting | eCR (eICR), HL7 v2 immunization messaging, FHIR IGs |
| Research and registries | De-identified or consented cohorts | Bulk Data, FHIR-based registry IGs |
For the broader conceptual picture, see FHIR and healthcare interoperability.
Point-to-point integration can ignore some of these concerns. Multi-party exchange cannot.
Without a national patient identifier in the US, linking records across organizations relies on demographic matching, enterprise master patient indexes and, increasingly, identity verification at the point of access. FHIR defines a Patient `$match` operation, but match quality depends on the underlying algorithm and data hygiene, which is where specialist experience shows.
Two systems both sending Observation resources can still disagree on meaning when one uses local lab codes and the other LOINC. Normalization pipelines map local codes to standard vocabularies, keep the original coding alongside, and flag unmapped values for review.
Multi-party exchange must respect patient consent and special protections, such as 42 CFR Part 2 substance use disorder records. Provenance resources record where each fact came from, which helps receivers judge trust and trace errors back to the source.
Multi-party programs usually begin with a governance and use-case definition phase, because technical choices depend on what participants have agreed to share and why. Delivery then proceeds through a pilot with a small set of participants, refinement of onboarding and data quality processes, and phased expansion. Each new participant brings its own systems and data quality, so the onboarding process becomes the product.
Regulatory timelines are fixed
CMS-0057-F sets compliance dates for impacted payers that do not move with your project plan. Work backwards from the dates on CMS.gov and leave time for partner testing.
The healthcare interoperability companies directory includes both platforms and service firms. Questions that separate them:
Interoperability programs are often split into an advisory and design phase, a platform license or subscription, and per-participant onboarding services. Cost depends on participant count, data domains in scope, matching and normalization complexity, consent requirements and regulatory deadlines. Because exchange networks keep growing after launch, ask how onboarding cost per participant changes over time, not only what the initial build costs. Strategy-only engagements are covered under HL7 FHIR consulting.
FHIR integration typically connects specific systems. Data interoperability addresses exchange among many organizations, where identity matching, terminology, consent and governance become central. A program may include many individual integrations.
The Trusted Exchange Framework and Common Agreement is a US nationwide framework for health information exchange through Qualified Health Information Networks. Exchange began largely with document-based query, and the framework has a published roadmap toward FHIR-based exchange. Check HealthIT.gov for current status.
The rule applies to Medicare Advantage organizations, state Medicaid and CHIP fee-for-service programs and managed care entities, and issuers of Qualified Health Plans on the Federally-facilitated Exchanges. Confirm applicability with your compliance team.
If you aggregate data about the same people from multiple sources, you need some form of identity resolution. That might be a dedicated EMPI, a service from your exchange platform, or a matching service built into your pipeline.
