CMS Pub. 100-04, ch. 18, § 10.2
Billing Requirements
A. Edits Not Applicable to Claims for Pneumococcal, Influenza, Hepatitis B or
COVID-19 Vaccines and Administration
The Common Working File (CWF) and shared systems bypass all Medicare Secondary
Payer (MSP) utilization edits in CWF on all claims when the only service provided is
pneumococcal, influenza, hepatitis B or COVID-19 vaccine and/or their administration.
This waiver does not apply when other services, (e.g., office visits), are billed on the
same claim as pneumococcal, influenza, hepatitis B or COVID-19 vaccinations. If the
provider knows, or has reason to believe that a particular group health plan covers
preventive vaccines and their administration, and all other MSP requirements for the
Medicare beneficiary are met, the primary payer must be billed.
First claim development alerts from CWF are not generated for pneumococcal, influenza,
hepatitis B or COVID-19 vaccine. However, first claim development is performed if
other services are submitted along with pneumococcal, influenza, hepatitis B or COVID-
19 vaccines.
See Pub. 100-05, Medicare Secondary Payer Manual, chapters 4 and 5, for
responsibilities for MSP development where applicable.
B Institutional Claims
Chapter 25 of this manual provides general billing instructions that must be followed for
institutional claims.
The following “providers of services” may administer and submit institutional claims to
the A/B MACs (A) for these vaccines:
Hospitals;
Critical Access Hospitals (CAHs);
Skilled Nursing Facilities (SNFs);
Home Health Agencies (HHAs);
Hospices;
Comprehensive Outpatient Rehabilitation Facilities (CORFs);
Indian Health Service (IHS)/Tribally owned and/or operated hospitals and hospital-based
facilities; and
Rural Health Clinics (RHCs) and Federally Qualified Health Centers (FQHCs), effective
for dates of service on or after July 1, 2025.
Other billing entities that may submit institutional claims are:
Independent Renal Dialysis Facilities (RDFs).
Effective for dates of service on or after July 1, 2025, RHCs and FQHCs shall submit
institutional claims for pneumococcal, influenza, hepatitis B and COVID-19 vaccinations,
with or without a visit/encounter or qualifying visit on the same day. (See §10.2.2.2 of
this chapter for special instructions for independent RHCs and freestanding FQHCs.)
Institutional providers should bill for the vaccines and their administration on the same
bill. Separate bills for vaccines and their administration are not required. The only
exceptions to this rule occur when the vaccine is administered during the course of an
otherwise covered home health visit since the vaccine, or its administration is not
included in the visit charge. (See §10.2.3 of this chapter).
C Professional Claims
Billing for Additional Services
If a physician sees a beneficiary for the sole purpose of administering a Medicare covered
preventive vaccine, they may not routinely bill for an office visit. However, if the
beneficiary actually receives other services constituting an “office visit” level of service,
the physician may bill for a visit in addition to the vaccines and their administration, and
Medicare will pay for the visit in addition to the vaccines and their administration if it is
reasonable and medically necessary.
Nonparticipating Physicians and Suppliers
Nonparticipating physicians and suppliers (including local health facilities) that do not
accept assignment may collect payment from the beneficiary for the administration of the
vaccines, but must submit an unassigned claim on the beneficiary’s behalf. Effective for
claims with dates of service on or after February 1, 2001, per §114 of the Benefits
Improvement and Protection Act of 2000, all drugs and biologicals must be paid based on
mandatory assignment. Therefore, regardless of whether the physician and supplier
usually accept assignment, they must accept assignment for the vaccines, may not collect
any fee up front, and must submit the claim for the beneficiary.
Entities, such as local health facilities, that have never submitted Medicare claims must
obtain a National Provider Identifier (NPI) for Part B billing purposes.
Separate Claims for Vaccines and Their Administration
In situations in which the vaccine and the administration are furnished by two different
entities, the entities should submit separate claims. For example, a supplier (e.g., a
pharmacist) may bill separately for the vaccine, using the Healthcare Common Procedure
Coding System (HCPCS) code for the vaccine, and the physician or supplier (e.g., a
drugstore) who actually administers the vaccine may bill separately for the
administration, using the HCPCS code for the administration. This procedure results in
contractors receiving two claims, one for the vaccine and one for its administration.
For example, when billing for influenza virus vaccine administration only, billers should
list only HCPCS code G0008 in block 24D of the Form CMS-1500. When billing for the
influenza virus vaccine only, billers should list only HCPCS code 90658 in block 24D of
the Form CMS-1500. The same applies for the other Medicare covered preventive
vaccinations.
In situations such as a public health emergency when vaccines are supplied at no charge to providers, entities shall
submit claims for the administration of the vaccine only. For example, a provider or supplier may only submit a
claim for the HCPCS code for the administration of the vaccine. If the billing systems providers and suppliers use
will not allow submission of only the vaccine or only the administration, $.01 should be submitted as the charge for
the service that was not provided.
The contractor shall deny claims for vaccine reimbursement costs when the vaccine has been provided at no charge to
providers and suppliers.
