Summary
Maryland Medicaid will only reimburse COVID-19 vaccine administration claims submitted on CMS-1500 forms using appropriate CPT codes. UB-04 institutional claims for COVID-19 vaccine administration will be denied. Providers with previously denied UB-04 claims containing revenue code 0771 must resubmit on CMS-1500 forms to receive reimbursement.
Action Required
Immediately: Billing team must update claims submission procedures to require CMS-1500 forms (not UB-04) for all COVID-19 vaccine administration claims submitted to Maryland Medicaid. Update billing system rules and provider education materials to enforce CMS-1500 submission only. For any previously denied UB-04 claims with revenue code 0771: Billing team must resubmit those claims on CMS-1500 forms using the appropriate CPT codes from the Maryland Medicaid COVID-19 Reimbursable Vaccine and Infusion Code Fee Schedule. Failure to use CMS-1500 forms will result in automatic claim denials. Contact Christa Smith at christa.smith@maryland.gov for questions on specific vaccine administration CPT codes.
