What Are Care Gaps in Healthcare? A Plain-Language Guide for Practice Leaders
Understand how care-gap definitions, measure context and the available records fit together. Use this guide to interpret the topic before choosing a workflow, a measurement approach or software.
The label on a worklist is the beginning of that investigation. It does not tell the team, by itself, whether to arrange care, obtain a missing record or ask a clinician to review the situation. Keeping those possibilities separate makes the term more useful to the people responsible for acting on it.
What is a care gap, exactly?
A care gap concerns care that is still needed. The underlying expectation may come from an evidence-based recommendation or an established care plan. AHRQ recommends that practices deliberately select trustworthy evidence and incorporate agreed recommendations into their clinical information systems, rather than depend on each clinician remembering every recommendation. AHRQ guidance on selecting evidence
That makes the source of the expectation important. A worklist entry that says only "screening overdue" leaves several questions unanswered. Which screening? According to which recommendation or measure? What date or result did the system last receive? Who can confirm the appropriate next step?
Access and documentation belong in the same conversation. If a patient has been unable to obtain an appointment, record the access problem alongside the outstanding care. If a service may have happened elsewhere, record the unresolved documentation question. Neither situation is usefully described by a bare "open" status.
For a practice leader, the aim is to give the next person enough context to act responsibly. An administrator can organize the records and the handoff. Questions about an individual patient's clinical needs belong with the care team.
How do care gaps connect to HEDIS and quality scores?
HEDIS, the Healthcare Effectiveness Data and Information Set, is maintained by the National Committee for Quality Assurance. It provides standardized measures of healthcare performance. Its technical resources specify how data are collected and results calculated. NCQA HEDIS resources
An item on a quality worklist therefore needs a reporting context as well as a clinical context. The reader should be able to identify the program, measure and applicable year. A generic label such as "diabetes gap" is too broad to explain what the report is testing or what evidence it expects.
Keep two questions visible: "What care does this patient need?" and "What evidence does this report require?" The answers may involve the same service, but the report should not become a substitute for the clinical decision. Likewise, changing a reporting status is not evidence that a service was delivered.
For the terms and reporting-year distinctions, use our HEDIS measures explainer. For an FQHC's UDS work, consult the applicable HRSA reporting manual separately. HRSA publishes an annual UDS manual and year-specific reporting changes. HRSA UDS reporting guidance
Examples of care gaps and their source context
Preventive services and follow-up for chronic conditions are useful examples, but a list of examples is not a screening schedule. CMS's ACO toolkit discusses identifying needed services and using records from other providers to understand what remains outstanding. It does not establish one outreach or completion benchmark for all practices. CMS toolkit, care-gap lists
The table below is a discussion aid for reviewing a flag. It does not determine whether a patient qualifies for a service.
| What appears on the list | What to establish first | A useful question for the next owner |
|---|---|---|
| A preventive service is marked overdue | The source of the recommendation or measure, its period and the latest available record | Is care still needed, or is evidence of completed care missing? |
| Follow-up appears outstanding | The documented plan and any subsequent visit or result | Who can confirm the intended next step? |
| A payer list and the EHR disagree | The dates and evidence behind each entry | Which record explains the disagreement? |
| A service was completed outside the practice | The available outside report and the receiving system's requirements | What documentation needs to reach the responsible team? |
Avoid adding age cutoffs, testing intervals or payment values to this table from memory. Those details belong to their applicable source and version. The point of the table is to make the missing context visible before anyone treats the flag as an instruction.

How are care gaps identified in practice?
The existing records are the starting point. CMS describes ACOs using claims and EHR information to build care-gap lists, including information about services performed by other providers. Electronic clinical quality measures also use data extracted from EHRs or other clinical systems. CMS ACO toolkit, eCQI overview of electronic clinical quality measures
A practical review begins by naming the list being used. "The payer file received this week" and "the EHR report run this morning" are more informative descriptions than "the gap report." Add the reporting period and the record date where available, so the reviewer knows what is being compared.
Then examine the evidence for a manageable set of entries. If a patient says the service happened elsewhere, preserve that information as something to verify. If a record arrives, retain its source and date. If the two systems still disagree, leave a visible question for the responsible quality or clinical owner.
There is no need to assume a universal false-positive rate to make this work worthwhile. The useful result is a more intelligible list: items ready for an approved next step, items awaiting records and items awaiting qualified review. Measure those categories using your own definitions rather than borrowing an unsupported percentage from another organization.
What should a team verify before acting on a gap flag?
Before assigning outreach, ask whether the team can explain why the patient appears on the list. Check the patient identity, the item being flagged, the source and applicable period, and the evidence already available. Document any unresolved clinical question for the person qualified to answer it.
Consider a hypothetical example: a list marks a service as outstanding and the patient reports completing it at another organization. The next task is to verify the relevant record and have it reviewed through the practice's established process. Calling that service "not done" would erase the uncertainty; calling the gap "closed" would get ahead of the evidence. "Outside record requested" describes what the team knows and is doing.
The same precision helps after outreach. A patient reached by phone has been contacted. A patient with a booking has been scheduled. Neither status, on its own, establishes service completion. Keep the later documentation step visible, particularly when the service takes place outside the practice.
Financial questions should be handled with the same care. If a team wants to understand an incentive, ask the contract owner which program, measure and terms apply. A count of open flags alone is not a calculation of revenue lost or earned.
Where should a practice go next?
Start with the unresolved question, then use the resource that answers it. For terminology, read HEDIS measures explained. For day-to-day execution, explore care-gap closure workflows. For the measurement questions behind outreach reports, use our care-gap outreach measurement guide. If the process is understood and the decision is about tools, use the care-gap software buyer's guide.
A useful first review can be small: choose one existing list, explain what its flags mean and identify who handles each unresolved question. Bring a clinical owner and a reporting owner into that discussion where their decisions are needed. You should leave with clearer definitions and responsibilities, not an assumption that every item requires the same action.
