For two decades, quality reporting in managed care has leaned on a familiar crutch: when administrative data fell short, teams pulled charts. The hybrid method of HEDIS reporting, which lets health plans supplement claims with medical record review on a sample of members, has rescued countless rates in the months before submission. That era is ending. NCQA plans to phase out hybrid reporting by measurement year (MY) 2029, with a goal of fully digital HEDIS by MY 2030, and CMS is moving its own quality programs toward electronic and FHIR-based reporting. For health plans, provider groups and ACOs, the question is no longer whether quality becomes digital, but whether their data is ready when it does.

What ECDS Changes

Electronic Clinical Data Systems (ECDS) is NCQA's reporting standard for measures calculated from structured electronic data: administrative claims, EHRs, health information exchanges and registries, and case management systems. ECDS measures do not allow a medical record sample to fill in missing results. If the evidence is not in an electronic source the plan can access and validate, it does not count.

That shifts the work from retrospective abstraction to prospective capture. A blood pressure reading recorded in a note but not as a structured value, or a screening result scanned as a PDF, helps under hybrid. Under ECDS, it is invisible.

Where the Transition Stands in July 2026

NCQA laid out a proposed timeline for retiring hybrid measures in late 2024 and has since refined it into measure-specific pathways. The headline points as of this summer:

  • The MY 2029 endpoint for the hybrid method is unchanged. Some measures follow their original paths and others have revised timelines based on testing and realignment.
  • Several high-volume measures have already moved. Colorectal cancer screening, cervical cancer screening and childhood and adolescent immunization measures have been transitioning to ECDS. For MY 2026, Lead Screening in Children moved to ECDS-only reporting, statin therapy measures for cardiovascular disease and diabetes moved to ECDS, and an ECDS version of Blood Pressure Control for Patients With Diabetes became available for voluntary reporting.
  • Glycemic Status Assessment is next. NCQA plans optional ECDS reporting in MY 2027 and ECDS-only reporting by MY 2029.
  • Transitions of Care and Care for Older Adults are expected to gain ECDS versions in MY 2028, with hybrid reporting available until the method is retired.
  • Prenatal and Postpartum Care is slated for an ECDS, risk-based replacement by MY 2028, and the child and adolescent weight assessment measure is targeted for retirement in MY 2029 with a replacement in development.
  • New measures are ECDS-first. Recent additions are specified for electronic data from the start, and NCQA is expected to publish MY 2027 specifications later this summer.

CMS has followed NCQA's lead in Star Ratings by bringing respecified, ECDS-based measures into the program, with colorectal cancer screening among them. Medicare Advantage plans should assume that the measures with the most weight in their Star Ratings will increasingly depend on electronic data quality.

CMS's Direction on Digital Quality

On the provider and ACO side, the signals are just as clear. The CY 2027 Physician Fee Schedule proposed rule, released July 14, includes proposals and requests for comment that point toward FHIR-based digital quality reporting. For Shared Savings Program ACOs, CMS proposes a new Medicare eCQM collection type limited to assigned beneficiaries and seeks comment on a phased transition in which ACOs would need to be ready to report applicable measures through FHIR-based digital quality reporting around the end of the decade. Comments are due September 14, and details may change in the final rule.

CMS's new LEAD ACO model, beginning in 2027, likewise adds two eCQMs, glycemic status and controlling high blood pressure, with electronic reporting moving from optional to required in steps. Across programs, the message is consistent: structured, interoperable clinical data is becoming the basis of quality measurement.

What It Means at the Point of Care

Digital measurement rewards organizations whose clinicians record the right data in the right format during the visit. Practical implications:

  • Vitals must be structured. Blood pressure needs to be captured as discrete systolic and diastolic values, ideally with the most recent reading clearly identifiable.
  • Lab results must carry standard codes. A1c and other results should arrive with LOINC codes through lab interfaces, not as scanned documents.
  • Screenings need structured results. Depression screening, fall risk and functional status assessments should be recorded with validated instruments and coded results, not narrative.
  • Exclusions need documentation too. Hospice, palliative care, frailty and other exclusions only help when they are captured in data the measure logic can read.

Rethinking Supplemental Data

Supplemental data has long been the bridge between claims and charts. Under ECDS, it becomes the main road. That raises the bar for how supplemental data is collected, validated and audited.

  1. Inventory every source. List each EHR feed, lab interface, HIE connection, registry and provider-submitted file, along with the measures each supports.
  2. Measure completeness. For each source, track fill rates for the fields that matter: dates of service, result values, codes and member identifiers.
  3. Validate before load. Catch format errors, invalid codes and unmatched members when files arrive, not during audit season.
  4. Close the loop with providers. Share which data elements are missing by practice, and fix capture problems at the source.
  5. Prepare for audit. Document data lineage so auditors can trace each numerator hit to a validated source.

A 12-Month Readiness Plan

Organizations can treat the transition as a program rather than a scramble:

  • This quarter: Identify which of your hybrid-dependent rates would fall if chart review disappeared tomorrow. That gap is your digital exposure.
  • Next two quarters: Standardize structured capture of vitals, labs and screenings in your highest-volume practices, and expand electronic data feeds where coverage is thinnest.
  • Within a year: Report key measures through ECDS in parallel where optional, compare results to hybrid, and close the gap before reporting becomes mandatory.

Building the Data Foundation

A platform approach makes this manageable. Curitics validates incoming clinical and claims data before it loads, checking fill rates and format issues with row-level preview, and assembles it into a unified member record. HEDIS gap tracking shows which gaps remain open, and the Encounter Builder captures vitals, validated screenings and quality-gap closure as structured data during the visit, so the evidence digital measures require is created when care happens.

The hybrid method gave quality teams a second chance. Digital measurement does not. The organizations that invest now in capturing clean, structured data at the source will find that their quality rates reflect the care they deliver.
