Code the Shots for Flu Vaccine

Code the Shots for Flu Vaccine

 Various flu strains circulate each year. Be sure you can properly report the vaccine.

Influenza can be a serious condition, and the best way to avoid getting the flu is to have an annual flu vaccination. All Medicare patients may receive a covered flu vaccination, once per influenza season, and additional flu shots also may be covered, if medically necessary.
The exact vaccine product administered must be reported to meet the requirements of immunization registries, vaccine distribution programs, and reporting systems. Multiple CPT® codes are provided for a particular vaccine when the schedule (number of doses or timing) differs for two or more products of the same vaccine type (e.g., quadrivalent (IIV4), trivalent (IIV3)), or the vaccine product is available in more than one chemical formulation, dosage, or route of administration, as shown in Table A.
Table A: 2018 Flu Vaccine CPT® Codes

CPT® Description
Influenza virus vaccine, quadrivalent (IIV4)
90654-90658 Influenza virus vaccine, trivalent (IIV3)
90660 Influenza virus vaccine, trivalent, live (LAIV3)
90661 Influenza virus vaccine, trivalent (ccIIV3)
90662, 90653, 90666-90668 Influenza virus vaccine (IIV)
90664 Influenza virus vaccine, live (LAIV)
90672 Influenza virus vaccine, quadrivalent, live (LAIV4)
90673 Influenza virus vaccine, trivalent (RIV3)
90674, 90756 Influenza virus vaccine, quadrivalent (ccIIV4)
90682 Influenza virus vaccine, quadrivalent (RIV4)

To report the administration of a flu vaccine, the vaccine product codes must be used in addition to the immunization administration code(s).
For non-Medicare reporting, if the vaccine is administered without counseling, use either 90471-90472 (percutaneous, intradermal, subcutaneous, or intramuscular injections) or 90473-90474 (intranasal or oral: one vaccine (single or combination vaccine/toxoid)).
If the vaccine is administered with counseling, use 90460-90461 (Immunization administration through 18 years of age via any route of administration, with counseling by physician or other qualified healthcare professional).
For Medicare reporting, use G0008 Administration of influenza virus vaccine.

A Separate E/M Usually Isn’t Justified

If the vaccine is the only thing addressed at the patient visit, report only the vaccine product and the vaccine administration — do not report a separate evaluation and management (E/M) service.
Here’s an example of when it would be appropriate to separately bill an E/M service and a vaccine:

The patient is seen in the office for hypertension and receives an influenza vaccine. The physician reports the appropriate level E/M service code with ICD-10-CM diagnosis code I10 Essential (primary) hypertension, in addition to the flu vaccine and administration codes and ICD-10-CM code Z23 Encounter for immunization. This code indicates the patient is being seen to receive a prophylactic injection. Code Z23 may be used as either a first-listed or secondary code, depending on the main reason of the encounter. In this case, it would be listed second.

Do not report a separate E/M service for vaccine-only visits unless the E/M service meets the criteria for using modifier 25 Significant, separately identifiable evaluation and management service by the same physician or other qualified healthcare professional on the same day of the procedure or other service. (For more information on Modifier 25, read “Know the Right Time to Append E/M Modifiers” on pages 24-25 of the October issue.)

    What should I use for the ICD-10 code for complications/adverse effects from the flu vaccine, T50.B95A or is there one more appropriate?

  2. Janet Gribble says:

    Explain why code G0008 is the correct code for trivalent for flu vaccine.
