Other underimmunization status

This code indicates a patient has not received all recommended vaccinations according to the standard immunization schedule, but the specific reason for this underimmunization is not otherwise specified. It signifies a general state of incomplete vaccination without detailing the cause, such as refusal or medical contraindication.

Apply this code when a patient's immunization record shows they are behind on their recommended vaccine schedule, and the documentation does not provide a more specific reason for the deficit. This is appropriate for general underimmunization identified during routine check-ups or pre-procedure screenings where the underlying cause isn't fully elucidated or documented.

• Only use this code when a more specific underimmunization code (e.g., due to patient refusal, medical contraindication) is not applicable or documented.
• Always review the patient's medical record for any additional information that might support a more precise immunization status code.
• This code should be used in conjunction with codes for the specific vaccines that are missing or overdue, if known.
