Consider giving a preferred vaccine to your patients 65 and older. Preferred vaccines are potentially more effective than standard dose flu vaccines. There are 3 recommended vaccines:

  1. Fluzone High-Dose Quadrivalent vaccine
  2. Flublok Quadrivalent recombinant flu vaccine
  3. Fluad Quadrivalent adjuvanted flu vaccine

If one of these recommended vaccines isn’t available, give your patients a standard-dose flu vaccine instead.

Frequency & Coverage

  • The CDC recommends annual flu shots for everyone 6 months and older each flu season. September and October are the best times for most people to get vaccinated.
  • Medicare Part B covers the seasonal flu shot.
  • We cover additional flu shots if medically necessary. Patients can get flu shots twice in a calendar year during 2 different flu seasons, and we’ll pay for both shots.
  • Your patients pay nothing if you accept assignment. There’s no copayment, coinsurance, or deductible.
  • Find out when your patients are eligible for the flu shot. We give information for dates of service in the last 18 months:
    • CPT or HCPCS codes
    • Dates of service
    • NPIs who administered the shots

If you need help, contact your eligibility service provider.
