CMS Updates Methodology for Calculating COVID-19 Testing by Nursing Facilities

The Centers for Medicare & Medicaid Services (CMS) announced a change in its methodology for calculating county-level community infection rates for COVID-19. Facilities are expected to use the county-level color coded rating (green, yellow, or red) to determine the frequency for testing facility staff and residents in accordance with CMS guidance.

The earlier guidance and methodology required facilities to test staff once monthly if the county in which the facility is located had a positivity rate of less than five percent (< 5%); testing frequency increased to once each week for county positivity rates between five and 10 percent (5 – 10%) and twice weekly for county positivity rates that exceeded 10 percent (>10%). The shift in methodology will mean a change in the color-coding rates. For example, CMS’ new methodology classifies counties with both fewer than 500 tests and fewer than 2,000 tests per 100,000 residents, along with a positivity rate greater than 10 percent over 14 days as “yellow” whereas the earlier methodology would have put these counties in the red zone.
