COVID-19 Vaccine Procedure Code 91304 Is Now a Benefit

Last updated on

Note: Texas Medicaid managed care organizations (MCOs) must provide all medically necessary, Medicaid-covered services to Medicaid members who are enrolled in their MCO. Administrative procedures, such as prior authorization, precertification, referrals, and claims and encounter data filing, may differ from traditional Medicaid (fee-for-service) and from MCO to MCO. Providers should contact the member’s specific MCO for details.

Effective for dates of service on or after October 3, 2023, in accordance with the U.S. Food and Drug Administration’s (FDA’s) amended emergency use authorization for the Novavax COVID-19 vaccine, vaccine procedure code 91304 is now a benefit of Texas Medicaid, Healthy Texas Women (HTW), the Family Planning Program (FPP), the Children with Special Health Care Needs (CSHCN) Services Program, and Texas Health Steps.

Important Vaccine Reminders

As of October 3, 2023, vaccine procedure code 91304 may be billed with vaccine administration procedure code 90480.

Vaccines administered to individuals eligible for the Vaccines for Children (VFC) program should come from VFC-provided stocks. COVID-19 vaccine products submitted for reimbursement will be processed as informational only when administered to individuals who are 6 months through 18 years of age.

Texas Medicaid, CSHCN, FPP, and HTW only cover vaccines that are authorized or approved by the FDA.

Note: Procedure code 91304 will be assigned an interim rate until expenditures are approved and a permanent rate is adopted by Texas Medicaid. We will notify providers of the permanent rate in a future article. Services provided before the interim rate is assigned will receive the following explanation of benefits (EOB) 02008 notification: “This procedure code has been approved as a benefit pending the approval of expenditures. Providers will be notified of the effective dates of service in a future notification if expenditures are approved.” Once expenditures are approved, we will automatically reprocess the affected claims. Providers are not required to appeal the claims unless they are denied for other reasons after the claims reprocessing is complete. When the claims are reprocessed, providers may receive additional payment, which will be reflected on the Remittance and Status (R&S) Report.
