What ICD-9 code is used for the flu shot?

Answer 1

For an inpatient claim for reimbursement, the ICD-9-CM diagnosis codes would be V04.81 for the reason for an influenza vaccination (need for prophylactic vaccination against influenza) and V03.82 (need for prophylactic vaccination against streptococcus pneumoniae, aka pneumococcal pneumonia) for the pneumonia vaccination. The ICD-9-CM procedure codes would be 99.55, Prophylactic administration of vaccine against disease, for the pneumococcal vaccine and 99.52, Prophylactic vaccination against influenza, for the flu vaccination.

Outpatient claims are coded differently with more complex specificity related to patient Demographics, etc. than the inpatient ICD-9-CM codes. For a quick reference to the proper coding for these for an outpatient episode of care, see the related link below to the official CMS information for CPTand pharmaceutical codes and additional guidelines for coding for Medicare.
