F12.9 — Cannabis use, unspecified
F12.9 is a non-billable header ICD-10-CM code for cannabis use, unspecified. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with F12.9
These codes carry an Excludes1 note pointing at F12.9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F12.9 alone.
Risk adjustment
F12.9 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 history
F12.9 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
