J09.X2Influenza due to identified novel influenza A virus with other respiratory manifestations. J09. X2 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
ICD-10 requires only one code (Z23) per vaccination, regardless if single or combination. Report Z23 for all vaccination diagnoses.
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.
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.
Z23 is a billable diagnosis code used to specify a medical diagnosis of encounter for immunization.
