Inoculations and Vaccinations ICD-10-CM Coding Code Z23, which is used to identify encounters for inoculations and vaccinations, indicates that a patient is being seen to receive a prophylactic inoculation against a disease.
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.
If the immunization is related to exposure (eg, the administration of a Tdap vaccine as a part of wound care), the ICD-10 code describing the exposure should be used as the primary diagnosis code for the vaccine, and Z23 should be used as the secondary code.

Flu Vaccine Administration Coding +90472 Immunization administration (includes percutaneous, intradermal, subcutaneous, or intramuscular injections); each additional vaccine (single or combination vaccine/toxoid) (List separately in addition to code for primary procedure).
The American Medical Association issued a new Current Procedural Terminology (CPT) code for influenza vaccine Flucelvax, CPT 90674, effective August 1, 2016 for Medicare claims.
The Z23 code includes the following note: “Code first any routine childhood examination.” Therefore, when you provide immunizations in conjunction with a well-child visit, a code for routine child health examination should be reported first, followed by Z23 for any immunizations. This is similar to ICD-9 rules.
Z23 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM Z23 became effective on October 1, 2021.
Code 90471 is used when the drug is administrated by a medical assistant or nurse and the patient does not see the physician at all. This code would also be used for any patient 19 years of age or older regardless if physician is present and does face-to-face counseling.
