HEDIS measures list for 2026: every domain, explained for operations teams

Most HEDIS resources are written for health plan quality teams. Provider operations teams face a different problem: a payer sends a gap list built from these measures, and the front office, outreach staff, and referral coordinators need to know which work they can move.

This article is the domain-by-domain reference with that operations lens applied throughout. For the conceptual background on what HEDIS is, how data gets collected, and why payers care, start with the HEDIS measures explainer. This guide assumes the basics and focuses on the map.

HEDIS is a registered trademark of the National Committee for Quality Assurance (NCQA). NCQA updates the measure set every measurement year, retiring some measures, adding others, and moving more reporting toward digital data. Treat this article as an organized orientation. Use the current publication at NCQA's HEDIS program as the source of truth for exact specifications.

How the 2026 measure set is organized

NCQA groups the HEDIS measure set into six domains, each answering a different question about health plan performance. Individual measures and specifications can change with each annual update.

1. Effectiveness of care: did members receive recommended screenings, treatments, and follow-up?
2. Access and availability of care: could members get care when they needed it?
3. Experience of care: how do members rate their care and their plan?
4. Utilization and risk-adjusted utilization: how much care did members use, and how does that use compare with their risk profile?
5. Health plan descriptive information: what structural information describes the plan?
6. Measures collected through ECDS: which measures are reported from structured electronic clinical data systems?

NCQA describes the set as containing more than 90 measures, but the exact count changes with annual updates. Operations teams should focus on what each current domain and applicable measure demands from their workflows rather than memorizing a static count.

Effectiveness of care: the outreach-heavy domain

Effectiveness of care is the largest domain and the one where provider organizations often have the most operational leverage. These measures ask whether eligible members received recommended care, which connects many of them to outreach, scheduling, completion, and documentation. Familiar measure families include:

• Cancer screening, including breast, cervical, and colorectal cancer screening.
• Diabetes care, including glycemic status assessment, eye exams, kidney health evaluation, and blood pressure control for members with diabetes.
• Cardiovascular care, including blood pressure control and statin therapy for eligible patients.
• Behavioral health follow-up after hospitalization or emergency department visits, plus antidepressant medication management.
• Pediatric and adolescent care, including immunization status, well-child visits, and lead screening.
• Women's health and maternity measures, including prenatal and postpartum care timeliness and chlamydia screening.
• Older adult care, including transitions of care after discharge and osteoporosis management after a fracture.
• Respiratory and medication-safety measures, including appropriate testing and treatment and avoidance of potentially harmful drug combinations in older adults.

The operational pattern is consistent: identify the eligible member, reach them, get the next step scheduled, support completion, and capture documentation in a form the applicable measure logic accepts. That is the same pipeline described in the overview of what care gaps are and how they form. Where a specification uses a short follow-up window, including 7-day or 30-day windows in some measures, teams must confirm the applicable year and contract before configuring outreach.

Referral coordination also matters. A colorectal cancer screening gap may close through a gastroenterology referral, while a diabetic eye exam gap may close through an optometry or ophthalmology referral. If the referral loop leaks, the measure workflow can leak with it.

Access and availability of care: the front-door domain

Access measures ask whether members could get care. The exact measure roster, eligible populations, and timing windows change by measurement year, so operations teams should use the current NCQA publication and their payer-specific specifications rather than a static list.

Operationally, this domain is about the front door: how quickly the phone gets answered, how soon new patients can get appointments, and whether follow-up begins within the applicable specification window. When a current measure uses a short initiation window, long intake or appointment lead times put completion at risk.

The operational levers include scheduling capacity, faster intake processing, and outreach that converts a diagnosis or discharge into a booked appointment within the required timeframe.

Experience of care: the survey domain

Experience of care is measured through standardized member surveys, principally the CAHPS survey family administered on a plan's behalf. Provider organizations do not administer these plan surveys directly, but the questions reflect operational realities members experience at care sites, including appointment access, answered questions, and coordination between providers.

The operations takeaway is to treat experience measures as a lagging indicator of access and coordination performance. Long hold times, unreturned messages, and referral dead ends can surface later in survey results.

Utilization and risk-adjusted utilization: the efficiency domain

Utilization measures describe how much care members use, including ambulatory visits, inpatient stays, emergency department visits, and selected procedures. The risk-adjusted subset compares observed use with expected use given member risk and includes measures such as plan all-cause readmissions, emergency department utilization, acute hospital utilization, and hospitalization for potentially preventable complications.

For provider operations teams, the actionable measures in this domain are often tied to transitions. Readmissions and emergency department utilization connect to discharge follow-up outreach, timely post-discharge appointments, and medication reconciliation visits. Purely descriptive utilization measures, by contrast, are reported for information rather than managed directly by a practice.

Health plan descriptive information: the structural domain

This domain covers structural facts about the plan, such as enrollment by product line and provider board certification. There is no member-level outreach work here. Provider organizations touch the domain indirectly by keeping credentialing and directory data current with contracted plans. It belongs in the reference for completeness, not as a patient work queue.

Measures collected through ECDS: the data-capture domain

ECDS stands for Electronic Clinical Data Systems. It is a reporting method based on structured electronic sources such as EHR records, health information exchanges, case management systems, and registries rather than claims alone or manual chart review. The exact ECDS measure roster and transition schedule should be confirmed in the current NCQA publication.

The operational change is significant. Under hybrid reporting, plans can use manual chart abstraction to recover qualifying evidence. Under ECDS reporting, care that is not captured as structured data may not count. Documentation workflow design, including discrete fields, correct codes, and results filed where an interface can read them, becomes a quality performance issue as well as a billing issue.

Community health centers feel this data-capture burden acutely. The guide to HEDIS measure improvement for CHCs covers the documentation workflow in more depth.

Mapping domains to the work your team controls

The six domains compress into an operations planning table:

A practical way to use the map is to tag payer gap-list measures by domain and staff the resulting work accordingly. Effectiveness and ECDS measures need an outreach and documentation pipeline. Access measures need front-door capacity. Utilization measures need a transitions workflow. ACOs often run this exercise across an attributed population, an angle covered in the guide to ACO care gap closure.

Keeping your list current year over year

Because NCQA revises the set annually, build a lightweight annual review into the quality calendar rather than treating any list, including this one, as permanent.

• Pull the measure list for the upcoming measurement year from NCQA and note additions, retirements, and specification changes.
• Reconcile payer gap-list measure names against current NCQA names because payer labels can differ or lag.
• Flag measures moving to ECDS reporting and audit whether documentation captures the required data in structured form.
• Re-tag internal work queues by domain so outreach staff focus on measures their workflows can influence.
• Confirm every timing window in the applicable specification before encoding it in scheduling or outreach rules.

The bottom line

The HEDIS measure list becomes more manageable when operations teams sort it by domain. Effectiveness of care and ECDS-reported measures contain much of the work provider teams can influence, and both connect to a common pipeline: find the eligible patient, reach them, schedule the next step, support completion, and document it in structured form. Access measures are a front-door capacity problem, utilization measures are a transitions problem, and the remaining domains require different levels of provider involvement.

Teams that automate that core pipeline through care gap closure automation can run the work as a steady-state workflow rather than an annual scramble.
