HEDIS is a set of quality measures published by the National Committee for Quality Assurance and reported by most commercial, Medicare, and Medicaid plans. Each measure defines a numerator and denominator, for example, the share of eligible patients who completed a colorectal cancer screening, so plans and provider groups can be compared on the same footing.

Because HEDIS results feed Medicare Star Ratings and value-based contracts, closing HEDIS gaps has direct financial stakes. A care gap is simply an eligible patient who is missing a required service; the work is finding those patients and getting the screening, visit, or medication completed and documented before the measurement year closes.

That closure work is mostly outreach. Rivvi runs HEDIS gap-closure programs as real conversations over voice and text, calling the patients due for a mammogram, an A1c check, or a wellness visit, booking them, and writing the outcome back, from a branded number and inside TCPA rules.
