In development
Regulatory reporting that can show its work.
Health plans and providers file the same numbers to CMS, to states and to NCQA every year, and almost none of those numbers can be traced back to the claim, the rule and the version that produced them. PayerReporting is built around that trace: every figure in a filing carries a derivation record, so an auditor's question has a one-line answer.
HEDIS measure results
Admin, Hybrid and ECDS measures computed from your claims, enrollment and clinical feeds, with member-level evidence behind every numerator hit.
Encounter data
837 encounters validated against the edits that will actually reject them before they leave your building, and reconciled to the response files that come back.
Price-transparency files
Machine-readable files checked against the current data-element requirements, with the negotiated rates tied to the contract terms that set them.
Federal and state submissions
The recurring filings, each with a validated payload, a submission receipt, and a record of what changed since the last one.
Start with the HEDIS measure directory or the sample files.
Health plans
What a plan files, and what each filing depends on.
| Filing | To | Cadence | Depends on |

Providers
The provider side of the same filings.

HEDIS® measure directory
Every measure a plan can report, by domain.
Measurement Year 2026, reported in 2027. Filter by product line or collection method. Admin measures come from claims alone; Hybrid adds a chart-review sample; ECDS adds electronic clinical sources with no chart chase.

Sample files
What the files look like.
Synthetic data, real structure. These are the two shapes every HEDIS conversation comes down to: the plan-level results that go into NCQA's submission system, and the member-level evidence an auditor asks for behind them.

Connections
Where the filings go, and how they get there.
NCQA IDSS
HEDIS results submission. Audited plan-level rates, locked by the licensed auditor. Digital HEDIS (FHIR + CQL) results follow the same submission path.
CMS Encounter Data System
837P/837I encounters for Medicare Advantage via EDFES; MAO-002 and 277CA response reconciliation.
CMS HPMS
Part C and Part D reporting requirements, plan benefit packages, formulary submissions.
State Medicaid encounter systems
State-specific 837 companion guides and response files for managed-care encounter reporting.
Public MRF endpoints
Transparency in Coverage and hospital standard-charges files, published and validated against current schema requirements.
FHIR APIs (CMS-0057-F)
Patient Access, Provider Access, Payer-to-Payer and Prior Authorization APIs, due January 1, 2027.
Digital HEDIS toolchain
NCQA's measure logic is moving to FHIR and CQL, and the engine that runs it is open source. What is free, what is gated, and what each piece actually contains, checked September 2, 2026.
Firely CQL SDK open source
NCQA's official .NET engine for executing CQL/ELM, BSD-3 licensed, release v2.14.0 (August 2026). It runs measure logic; it ships no HEDIS logic. FirelyTeam/firely-cql-sdk
NCQA on GitHub open source
Ten public repositories: forks of the Firely engine, the CQL-to-ELM translator, a CQL expression-runner API, and a fork of CQL Studio with a HEDIS engine-test branch. github.com/ncqa-org
Bundled test content open source
The engine repository carries the CMS digital quality measure set (QICore 2025) as CQL and ELM, with a value-set sync against VSAC. VSAC needs a free UMLS key. HEDIS measures are not in the bundle.
Digital HEDIS Evaluation Toolkit by application
Sample measures, supporting documentation and testing tools for readiness assessment. The only route to NCQA test content without a license. Price not published. Apply at NCQA
Digital Quality Partner Program by application
NCQA's list of advisory and technical partners for planning and implementation. Requirements and fees not published.
Digital Content Services + Measure Certification licensed
Required before any HEDIS rate is sold or reported. Store measure bundles ($350 per measure) are internal, non-commercial, and forbid computing results without NCQA approval. Certification: apply February 15, certified March 31 to July 1.
