ONC Certification: What New EHR Vendors Need to Know in 2026
ONC certification is the gateway to the US healthcare market. Here is what the process actually involves, what it costs, and where new vendors get stuck.
Certification is market access
Without ONC certification, your EHR cannot participate in federal incentive programs. Providers cannot attest to Promoting Interoperability. Health systems will not consider you. Payers may not integrate with you.
Certification is not optional. It is the minimum bar for participation.
The certification landscape in 2026
The ONC Health IT Certification Program is governed by the 21st Century Cures Act and implemented through rules like HTI-1. The current requirements include:
- FHIR R4 API support (US Core profiles)
- SMART App Launch for third-party applications
- Information blocking compliance
- Clinical quality measure reporting capabilities
- Standardized APIs for patient and population services
- Security requirements including encryption, audit logging, and access controls
The certification process is administered by ONC-Authorized Certification Bodies (ONC-ACBs) like Drummond Group and InfoGard.
The real timeline
New vendors consistently underestimate the timeline. Here is what to expect:
Pre-submission: 3-6 months
- Gap analysis against certification criteria
- Test environment setup
- Documentation preparation
- Internal testing and remediation
Testing and review: 3-6 months
- Submission to ONC-ACB
- Functional testing
- Interoperability testing
- Security assessment
- Remediation cycles
Total: 6-12 months minimum
And that is if your product is already built to the spec. If you are retrofitting, add time.
Where vendors get stuck
FHIR API completeness
Having a FHIR endpoint is not enough. You need:
- All US Core profiles implemented correctly
- Proper search parameter support
- Bulk FHIR for population queries
- SMART App Launch with correct scopes
Clinical quality measures
CQM calculation is precise. The logic must match published specifications exactly. Off-by-one errors in date calculations or population criteria will fail testing.
Security requirements
Audit logging, encryption at rest and in transit, role-based access control, automatic session timeout. These are not nice-to-haves—they are testable criteria.
Documentation
Every criterion requires evidence. Screenshots, API responses, test results, configuration documentation. The documentation burden is significant.
Cost
Budget $150,000-$400,000 for initial certification depending on scope. Annual surveillance costs $50,000-$100,000. Engineering time is the largest hidden cost.
Strategy for new vendors
- Design to the criteria from day one—do not retrofit
- Use FHIR R4 as your internal data model, not just an external API
- Build CQM logic into your reporting layer early
- Engage an ONC-ACB for a pre-assessment before formal submission
- Budget for at least one remediation cycle
The standard to hold
Certification is not a one-time event. It is an ongoing compliance obligation. Build your engineering processes around it, not around it.
