J09
J09 — Influenza due to certain identified influenza viruses
Non-billable headerICD-10-CM
J09 is a non-billable header ICD-10-CM code for influenza due to certain identified influenza viruses. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Other codes that can never be billed with J09
These codes carry an Excludes1 note pointing at J09. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J09 alone.
- A08Viral and other specified intestinal infections
- G94Other disorders of brain in diseases classified elsewhere
- H67Otitis media in diseases classified elsewhere
- I41Myocarditis in diseases classified elsewhere
- J00Acute nasopharyngitis [common cold]
- J02.9Acute pharyngitis, unspecified
- J03.9Acute tonsillitis, unspecified
- J06Acute upper respiratory infections of multiple and unspecified sites
Risk adjustment
J09 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead J09
1 child code. Green means billable.
