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.
Vaccine Administration Code(s) Administration codes track which dose in the regimen is being administered. NDC 10/NDC11 The National Drug Code (NDC) uniquely identifies human drugs in the United States; it can be found on the vial containing the vaccine.
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.
