PREP Act Ninth Amendment – Overview and Audit Guidance for Subcutaneous REGEN-COV

The ninth amendment to the Public Readiness and Emergency Preparedness (PREP) Act was published in the Federal Register on September 14th, 2021, which granted pharmacists the authority to order and administer COVID-19 therapeutics and qualified pharmacy technicians and pharmacy interns to administer COVID-19 therapeutics under the supervision of a pharmacist. The PREP Act only covers COVID-19 therapeutics by subcutaneous, intramuscular, or oral administration—therefore, IV infusion would not be covered under this amendment.

At the time of publishing, only one COVID-19 therapeutic is available for administration under the ninth amendment of the PREP Act. The co-formulated solution, REGEN-COVTM, qualifies because it has FDA emergency use authorization (EUA) for administration via subcutaneous injection in addition to IV infusion. REGEN-COVTM contains two monoclonal antibodies (mAbs), casirivimab and imdevimab, and is authorized for the treatment of certain patients with COVID-19 and for post-exposure prophylaxis in eligible patients.1,2

When billing REGEN-COVTM, request reimbursement only for the administration fee (aka incentive amount) since the therapeutic agent is provided to the pharmacy at no cost by the federal government. To bill Medicare, the pharmacy must be enrolled as a Part B provider and utilize a medical billing intermediary. For claims billed to plans other than Part B, REGEN-COVTM may or may not be covered by either the pharmacy or medical benefit and cost-sharing is possible. Based on guidance from CMS, below are the billing codes for REGEN-COVTM (NDC 61755-0039-01; 10 mL vial).

PAAS Tips: 

  • Robust documentation is extremely important – be audit-ready by having all the following for each claim:
  1. A placeholder hardcopy
  2. Confirmation of the patient’s eligibility with a signed attestation (COVID-19 treatment also requires valid test results)
  3. An administration log signed and dated by the patient, pharmacist, and staff who administered the therapeutic agent
