(a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
Z23 is the ICD-10 code that identifies an encounter for an immunization.
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.
Z23 is a billable diagnosis code used to specify a medical diagnosis of encounter for immunization.
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.
For immunization administration of any vaccine that is not accompanied by face-to-face counseling of the patient/family or for administration of vaccines for patients over 18 years of age, report codes 90471-90474. Code 90460 is reported once for the first component of each vaccine or toxoid administered by any route.
