Closing HEDIS Gaps: A Practical Playbook for Better Scores

Better HEDIS performance isn't about working harder during measurement season — it's about having clean data, complete documentation, and the right timing all year. Here's a practical framework for finding and closing care gaps before they cost you.

Understand what a "gap" really is

A HEDIS gap means a member was due for a service — a screening, a lab, a follow-up — and the record doesn't show it happened. Sometimes the care truly didn't occur. Just as often, it did occur but wasn't documented or coded in a way the measure can capture. Both are fixable, but they need different responses.

Start with accurate, timely data

You can't close what you can't see. Gap lists are only as good as the data behind them. Reconciling claims, lab feeds, and EMR data so the gap list reflects reality is step one — otherwise your team wastes time chasing gaps that are already closed, and misses ones that are truly open.

Separate "care gaps" from "documentation gaps"

• Care gaps: The service is genuinely needed. These require outreach — scheduling the mammogram, the A1c test, the wellness visit.
• Documentation gaps: The care happened but isn't captured correctly. These require chart review and coding cleanup, not patient outreach.

Triaging gaps into these two buckets keeps your team from sending an outreach call for a screening the patient already completed.

Close gaps at the point of care

The most efficient time to close a gap is while the patient is already in the office. Surfacing open gaps to providers inside the EMR — at check-in and during the visit — means care and documentation happen together, in one encounter, instead of triggering separate outreach later.

Time your effort to the calendar

Gaps closed early in the year are far cheaper than a scramble in Q4. A steady, year-round cadence — monthly gap review, point-of-care prompts, and periodic documentation audits — beats a season-end sprint every time, and it produces better scores with less stress.

Build the feedback loop

Track which gaps close, which don't, and why. That insight tells you where to focus — whether it's a documentation issue with a particular measure, an outreach process that isn't converting, or a data feed that needs fixing. Over time, the loop turns gap closure from a fire drill into a predictable, improving process.
