CMS has moved from encouraging interoperability to enforcing it. The 21st Century Cures Act, CMS-0057, TEFCA, and ONC’s HTI rules now carry real penalties and certification gates. The four data points below show why interoperability has shifted from a five-year roadmap item to a 12-month deliverable for every regulated healthcare entity in the US.
| Stat | What it means |
|---|---|
| $19.6B | Projected size of the global healthcare interoperability solutions market by 2032, growing from $5.6B in 2023 at a 14.9% CAGR. |
| $1M | Maximum civil monetary penalty per information blocking violation under the 21st Century Cures Act. The first enforcement actions began landing in 2024. |
| 96% | US hospitals with FHIR API capability by the end of 2024, up from 24% in 2019. The remaining 4% are now the laggards, not the early adopters. |
| January 2027 | CMS-0057 compliance deadline for Patient Access, Provider Access, Prior Authorization, and Payer-to-Payer FHIR APIs across all CMS-regulated payers. |
Bacancy covers the full interoperability stack, from standards-based API development through data normalization, EHR connectivity, and the regulatory work that turns architecture into compliance. Our services are built for HIPAA-covered environments, CMS-regulated payers, and the legacy data formats every healthcare organization still runs on. Pick the services below that match where your organization is today.
We build FHIR R4 and SMART on FHIR APIs that meet ONC certification criteria, including the (g)(10) criterion required for EHR vendors. Our team handles FHIR profiling against US Core, Da Vinci, and CARIN implementation guides. Outputs include patient-access APIs, provider-access APIs, bulk data APIs, and the conformance testing artifacts required for certification.
We integrate your platform with Epic, Cerner Oracle Health, Athenahealth, NextGen, eClinicalWorks, Allscripts, and MEDITECH using SMART on FHIR, HL7 v2 interfaces, custom REST APIs, or hybrid integration patterns. For deeper named-EHR work, see our healthcare EHR integration services.
FHIR is the future. HL7 v2 is the present. CDA documents and DICOM imaging are everywhere. Our team builds the translation layer that maps between legacy standards and modern FHIR resources, so you do not have to wait for every upstream system to modernize before your interoperability program ships.
We help healthcare organizations prepare for TEFCA participation, including QHIN connectivity assessment, technical architecture for exchange purposes, IAS implementation, and the operational readiness audit. Useful for payers, providers, and health information exchanges joining the national framework.
We build the data exchange capabilities required by USCDI v3, CMS-0057 (Patient Access, Provider Access, Prior Authorization, Payer-to-Payer), and CMS Interoperability and Patient Access rules. Includes the FHIR API surface, audit logging, and the documentation regulators ask for.
Raw clinical data arrives in dozens of formats with inconsistent terminology and duplicate patient records. We build data normalization pipelines, terminology services (LOINC, SNOMED CT, RxNorm, ICD-10), and master patient index (MPI) services that deliver one clean view of the patient across your stack.
Our team designs, builds, and migrates healthcare interface engines using Mirth Connect, Rhapsody, Cloverleaf, and cloud-native alternatives. Useful for organizations replacing legacy engines, moving to cloud-hosted integration, or scaling beyond what their current interface engine can handle.
We build dedicated healthcare API gateways that handle authentication (OAuth 2.0, SMART on FHIR), rate limiting, audit logging, consent management, and the operational tooling regulated APIs require. Built on AWS HealthLake, Azure Health Data Services, Google Cloud Healthcare API, or self-hosted FHIR servers like HAPI, Aidbox, or Kodjin.
Interoperability programs come in different shapes. Some clients need a single FHIR API delivered fast. Others need a multi-year architecture program. A few need their stalled in-flight build rescued. We offer four engagement models, with the flexibility to switch as your interoperability program matures.
Best for organizations with a clear scope and timeline. Specific FHIR API, single EHR integration, single TEFCA readiness sprint, or one named data exchange. You define the scope, we agree on price and delivery dates, and we ship. Typical duration: 6 to 16 weeks.
We act as your full interoperability architecture partner across a multi-year program. Strategy, architecture, standards governance, build, certification, and operations. Single delivery roadmap, single point of accountability. Best for health systems, large payers, and health information exchanges modernizing their data exchange architecture.
A long-term dedicated team assigned to your interoperability roadmap. You get a healthcare solution architect, FHIR engineers, HL7 specialists, standards experts, and a delivery lead. Reports into your CIO, CMIO, or VP of Engineering. Best for organizations with ongoing integration backlogs and standards work.
Focused engagements to prepare for ONC (g)(10) certification, CMS-0057 compliance, TEFCA QHIN participation, or USCDI v3 readiness. Includes gap assessment, technical remediation, documentation, conformance testing, and audit support. Typical duration: 8 to 24 weeks.

Three recent client engagements where we turned standard complexity into shipped infrastructure.
A regional health plan covering 2.4M members needed full CMS-0057 compliance across Patient Access, Provider Access, Prior Authorization, and Payer-to-Payer FHIR APIs. We built the FHIR API surface on Azure Health Data Services, integrated with their core claims platform, and submitted CMS attestation 4 months ahead of the deadline. Zero member-facing disruption, zero CMS audit findings.
Discover
A statewide health information exchange connecting 32 hospitals and 600 ambulatory practices needed a unified FHIR API surface across mixed EHR environments (Epic, Cerner, Athenahealth, Allscripts). We built a normalization layer that translates legacy HL7 v2 messages into FHIR R4 resources, deployed on AWS HealthLake. Daily message volume: 4.2M HL7 messages, normalized and exposed as FHIR in under 200ms.
Discover
A connected patient monitor manufacturer needed to push real-time vitals data into hospital EHRs across dozens of customer sites. We built a SMART on FHIR app, an HL7 v2 ORU bridge for non-FHIR environments, and a device data normalization layer. The platform now streams vitals from 28,000 connected devices across 40+ hospital networks.

Our delivery process is structured around six phases that repeat across every engagement, scaled to fit scope.
1. Discovery and Standards Assessment
We map your current systems, integration architecture, standards usage, and regulatory exposure. We benchmark your current state against CMS rules, ONC certification criteria, and USCDI v3 requirements.
2. Architecture and Roadmap Design
Our healthcare solution architects design the target interoperability architecture: API surface, FHIR server, terminology services, MPI, integration engine, and security baseline. Roadmap built in 90-day phases so leadership can fund and sequence with confidence.
3. Standards Implementation and Profiling
We profile your FHIR resources against US Core, Da Vinci, CARIN, and any payer or provider-specific IGs you need to conform to. Conformance testing built into the workstream from day one, not bolted on at the end.
4. Build and Integration
Our engineers build the APIs, integration adapters, and data normalization pipelines. Modular delivery in two-week sprints. EHR integrations, HIE connectivity, payer APIs, and device feeds delivered as separate workstreams that compose into one architecture.
5. Conformance Testing and Certification
We run your build through Inferno, Touchstone, and other ONC-recognized testing suites. We prepare and submit the documentation for ONC (g)(10) certification, CMS-0057 compliance attestation, or TEFCA QHIN onboarding as needed.
6. Operations, Monitoring, and Continuous Compliance
After go-live, we monitor API uptime, audit logs, conformance drift, and the standards updates that come out of every quarterly HL7 release. Continuous compliance instead of one-time certification.
Selecting a healthcare interoperability services partner mostly comes down to one question: do they actually understand the standards stack, or are they FHIR-only? At Bacancy, 14 years of healthcare engineering means our team speaks FHIR, HL7 v2, CDA, DICOM, X12, NCPDP, and IHE profiles, plus the regulatory rules that sit on top of them. For organizations also building toward revenue cycle management or medical billing software, our interoperability work plugs in directly. We are not a generalist development shop learning healthcare standards on your project.
Healthcare interoperability services are professional services that build the standards-based connections between healthcare systems. They typically cover FHIR API development, EHR integration, HL7 v2 and CDA bridging, TEFCA readiness, USCDI compliance, terminology services, master patient index, and the regulatory work required by CMS and ONC. At Bacancy, we deliver the full stack.
Healthcare interoperability is required by federal regulation. The 21st Century Cures Act, CMS Interoperability and Patient Access Rule, and CMS-0057 all impose specific FHIR API and data exchange requirements on payers, providers, and EHR vendors. Information blocking penalties can reach $1 million per violation. Beyond compliance, interoperability is what makes value-based care, population health, AI, and care coordination possible.
A focused FHIR API build typically runs 6 to 12 weeks. A single EHR integration runs 4 to 16 weeks depending on scope and the target system. CMS-0057 compliance programs for payers typically run 6 to 12 months. A full enterprise interoperability program at a health system or HIE runs 12 to 24 months in phased delivery.
A focused FHIR API build runs $50,000 to $200,000. A TEFCA readiness program runs $150,000 to $500,000. A CMS-0057 compliance build for a payer runs $300,000 to $1.5M depending on size. Full enterprise interoperability platforms range from $500,000 to $2M+. Bacancy scopes pricing to your specific environment and regulatory deadlines.
EHR integration services focus on connecting your platform to specific named EHRs (Epic, Cerner, Athenahealth). Healthcare interoperability services are broader. They cover the full standards stack (FHIR, HL7 v2, CDA, X12, DICOM, IHE), all the regulatory frameworks (CMS, ONC, TEFCA, USCDI), and the architecture-level work that makes interoperability sustainable. EHR integration is one workstream inside interoperability. See our healthcare EHR integration services for narrower EHR work.
Yes. We help EHR vendors and health IT developers prepare for ONC Health IT Certification (g)(10) criterion. Includes FHIR API conformance to US Core IG, security and SMART on FHIR implementation, audit logging, documentation, and Inferno conformance testing support.
CMS-0057 is the CMS Interoperability and Prior Authorization Final Rule. It requires CMS-regulated payers to expose four FHIR APIs by January 2027: Patient Access, Provider Access, Prior Authorization, and Payer-to-Payer. Payers also need to publish electronic prior authorization decisions within specified timeframes. We build the FHIR API surface, the integration with claims platforms, and the audit infrastructure required by the rule.
Our team works with US Core, Da Vinci (CRD, DTR, PAS, PDex, HRex), CARIN BB and Consumer Directed Payer Data Exchange, International Patient Summary, USCDI+ data classes, and custom payer or provider implementation guides. We also profile FHIR resources for organizations creating their own conformance requirements.
Bacancy is ISO 27001:2013 certified as an organization. Our team holds individual certifications including HL7 FHIR Foundation, AWS Solutions Architect, Microsoft Certified Azure Solutions Architect, and Google Cloud Professional Architect. We sign Business Associate Agreements (BAAs) with all healthcare clients.
