Summary
Connecticut Medicaid now requires specific diagnosis codes (U07.1, Z20.828, Z03.818, or Z11.59) on all COVID-19 Testing Group claims, effective retroactively to March 18, 2020. Claims without these codes will be denied, and previously paid claims lacking these codes will be recouped.
Action Required
Immediately: Billing team must update all COVID-19 Testing Group claims to include at least one required diagnosis code (U07.1, Z20.828, Z03.818, or Z11.59) in any position on the claim. Review and resubmit any previously submitted COVID-19 Testing Group claims that lack these codes to avoid recoupment. Update billing system rules to require these codes for COVID-19 testing claims under Connecticut Medicaid's uninsured coverage group.
