Diameter Health is certified by both the NCQA and ONC to enable client success.

The National Committee for Quality Assurance (NCQA) was founded in 1990 to improve the quality of healthcare through measurement, transparency, and accountability.   Starting with measuring and accrediting health plans through the Healthcare Effectiveness Data and Information Set (HEDIS), NCQA now also measures the quality of healthcare providers and practices.

Diameter Health is certified by the NCQA and ONC to report eCQM clinical quality measures. This dual certification evaluates and approves our logic to calculate electronic clinical quality measures (eCQM) using electronic clinical data. Certified data in the approved QRDA format can be used as supplemental data and added to other records to calculate HEDIS measures at the health plan level.
