COVID-19 Vaccines and Monoclonal Antibodies

Medicare Part B Payment for COVID-19 Vaccines and Certain Monoclonal Antibodies during the Public Health Emergency

CMS has released a set of toolkits for providers, states and insurers to help the health care system prepare and assist in swiftly administering these products once they become available.  These resources are designed to increase the number of providers that can administer the products and ensure adequate reimbursement for administration in Medicare, while making it clear to private insurers and Medicaid programs their responsibility to cover these products at no charge to beneficiaries.  This webpage provides the payment allowances and other related information for these products.  For more information, review the COVID-19 provider toolkit.

Payment Allowances and Effective Dates for COVID-19 Vaccines and their Administration During the Public Health Emergency:(DOS = Date of Service, TBD = To Be Determined)

^[1] Since we anticipate that providers, initially, will not incur a cost for the product, CMS will update the payment allowance at a later date.  Providers should not bill for the product if they received it for free.

^[2] These rates will also be geographically adjusted for many providers. For providers and suppliers with payments that are geographically adjusted by the methodology used by the Medicare Physician Fee Schedule (MPFS), files with the geographically adjusted payment rates for COVID-19 vaccine administration are included in the “Additional Resources” section below. Certain settings utilize other payment methodologies, such as payment based on reasonable costs.

^[4]On April 16, 2021, the FDA revoked the EUA that allowed for the investigational monoclonal antibody therapy bamlanivimab, when administered alone, to be used for the treatment of mild-to-moderate COVID-19 in adults and certain pediatric patients. Due to this revocation, Medicare will not pay for claims with HCPCS codes M0239 or Q0239 with dates of service after 4/16/2021.

^[5]On June 3, 2021, the FDA issued an updated EUA for casirivimab and imdevimab that changed the allowed dosing regime from 2400 mg to 1200 mg, and allowed for the administration of the combination product via subcutaneous injection in limited circumstances. Due to these changes, CMS has issued a new product code for casirivimab and imdevimab (Q0244), and updated the descriptors for the existing administration codes (M0243/M0244). 

^[6] On July 30, 2021, the FDA revised the EUA for casirivimab and imdevimab to allow its use for post-exposure prophylaxis (PEP) in certain adult and pediatric patients. For patients who meet the criteria for repeat dosing, the authorized dosage is an initial dose of 1200 mg, followed by subsequent repeat dosing of 600 mg once every 4 weeks for the duration of ongoing exposure. Due to this update, CMS has issued a new product code for casirivimab and imdevimab of 600 mg (Q0240), and 2 new codes for the administration of repeat doses of casirivimab and imdevimab (M0240/M0241). Providers and suppliers administering casirivimab and imdevimab for PEP should use M0243 or M0244 for administering the first dose, and M0240 or M0241 for administering subsequent repeat doses.

^[7] When the government provides monoclonal antibody products to treat COVID-19 for free, providers should only bill for the administration; don’t include the monoclonal antibody product codes on these claims. If you got the product for free, and your systems require a product code to bill for the administration, enter $0.01 for the billed amount.
