Medicare Part B Vaccine Coverage

Vaccine Coverage for Medicare Part B

Medicare Part B provides preventive coverage only for certain vaccines. These include:

  • Influenza: once per flu season (codes 90655-90658, 90660, 90662)
  • Pneumococcal: once per lifetime (codes 90669 and 90732)
  • Hepatitis B: for persons at intermediate- to high-risk (codes 90740, 90743, 90744, 90746, 90747)

Administration services for these preventive vaccines are reported to Medicare using HCPCS codes as follows:

  • G0008 administration of influenza virus vaccine
  • G0009 administration of pneumococcal vaccine
  • G0010 administration of Hepatitis B vaccine

The diagnosis codes to report with these preventive vaccines are:

  • V04.81 when influenza vaccine is administered but pneumococcal is not
  • V06.6 when both the influenza and pneumococcal vaccines are administered
  • V03.82 when administering pneumococcal vaccine but not the influenza vaccine
  • V05.3 when administering the hepatitis B vaccine

Other immunizations are covered under Medicare Part B only if they are directly related to the treatment of an injury or direct exposure (such as antirabies treatment, tetanus antitoxin, or booster vaccine, botulin antitoxin, antivenin, or immune globulin)

Coverage of other vaccines provided as a preventive service may be covered under a patient's Part D coverage.

Billing Considerations for Part B Vaccines

Whether participating or non-participating in Medicare, physicians must accept assignment of the Medicare vaccine payment rate and may not collect payment from the beneficiary for the vaccine.

Non-participating physicians may choose not to accept assignment on the administration fee. When a non-participating physician or supplier provides the services, the beneficiary is responsible for paying the difference between what the physician or supplier charges and the amount Medicare allows for the administration fee. The limiting charge provision does not apply to the influenza benefit.

The influenza and pneumococcal vaccines and the administration of these vaccines are not subject to the Medicare Part B deductible or co-insurance. Medicare pays at 100% of the allowable amounts. However, the Hepatitis B vaccine and administration are subject to the deductible and co-insurance. Medicare pays at 80% after the patient has met their Part B deductible.

Medicare will pay two administration fees if a beneficiary receives both the influenza virus and the pneumococcal vaccine on the same day.

Claims for the hepatitis B vaccine must include the name and NPI of the ordering physician, as Medicare requires that the hepatitis B vaccine be administered under a physician’s order with supervision. This is not necessary for the influenza and pneumococcal vaccines for which Medicare does not require a physician's order or supervision. (Note that state law may require an order and/or supervision.)
