How do you code influenza type A?

Answer 1

J09.X2 / 90685 / Z23

Okay. Are you referring to a procedure of vaccination for Infuenza A? Or are you referring to a diagnosis of Influenza A?

The vaccination for influenza A is 90685 (procedure/the vaccine itself and the administration of the biological), and for insurance to reimburse for that, it must have an ICD-10 code of Z23 (wellness/illness prevention code).

If you are describing a patient's illness, a reason for a medical visit - the ICD-10 is J09.X2 (active illness code).
