Documentation, Billing Instructions, and Enrollment
Documentation and billing instructions — preserve EUA evidence; omit product codes when product free
Maintain medical record documentation that demonstrates the EUA terms were met and supports the medical necessity of the infusion; documentation must include the name of the practitioner who ordered or authorized the infusion even when claims are submitted on a roster bill. When COVID-19 monoclonal antibody doses are provided by the government at no charge, bill only for the administration and do not include monoclonal antibody product codes on the claim.
- Keep records showing EUA requirements were satisfied and medical necessity.
- Include ordering practitioner's name on documentation for each administration, including roster-billed services.
- If product provided free by government, submit claims only for administration and omit product HCPCS codes.
Enrollment and SNF billing discretion — Medicare-enrolled immunizers may bill directly
Medicare-enrolled immunizers (for example, pharmacies, infusion centers, and home health agencies) may bill Medicare directly for vaccinating or infusing SNF residents under CMS enforcement discretion; these providers follow the same enrollment process as other COVID-19 vaccine/infusion administrators.
- CMS will exercise enforcement discretion of SNF consolidated billing to allow direct billing and reimbursement by Medicare.
- Providers must follow the standard Medicare enrollment process for COVID-19 vaccine/infusion administrators.
Key Terms and Billing Concepts
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
