Quality Gap Closure
How the ZAP helps you assess and close quality gaps by filling in what claims data misses.
Quality management is a key responsibility for many provider organizations, with significant implications for both patient safety and value-based payments. However, many organizations struggle to accurately assess their in-year performance on quality measures, resulting in inefficient use of care management resources, missed quality targets, and loss of revenue.
By filling in gaps in claims data and surfacing relevant information to both population health analysts (via the Zus data marts and query library) and care teams (via the ZAP and Zus EHR Integrations), Zus helps organizations efficiently identify and close care gaps and improve care quality.
What the ZAP shows
Quality gap closure is about finding patients who are due for a screening, test or follow-up. The ZAP brings a patient's history, visits, labs, pharmacy fills and screenings from outside sources into one record. That helps you see whether a screening or test was already done somewhere else.
Data sources
- Labs: 2 years of Quest Diagnostics lab history, plus new results as they come in. See Lab Networks.
- Pharmacy: for medications tied to a quality measure (CMS eCQM or HEDIS), Zus refreshes medication history no more than 7 days after the expected refill date. See Pharmacy Network.
- Visits: encounters are deduplicated by date and labeled ambulatory, inpatient, emergency and so on, so you can tell which visit a result came from. See Encounter Lens.
Kidney health results
Many EHRs and lab feeds send eGFR and uACR results as free text. Before August 2026, valid results sent that way could be left out of measure calculations, such as the HEDIS Kidney Health Evaluation for Patients with Diabetes (KED). Zus now turns these results into a structured value and unit.
- Results reported with a comparator, like
>60, count as valid results. They show correctly in evidence cards and clinical notes. - Values outside a clinically plausible range are flagged, not converted.
- Results from 2025 forward have been updated. You don't need to do anything.

Record requests must be for treatmentRequests to CommonWell, Carequality and Surescripts must be for treating a patient. You can't query the networks only to collect evidence for quality reporting. See Risk Adjustment.
