Add a secondary code to capture the detail described below.
- code to identify:
- alcohol abuse and dependence (F10.-)
- exposure to environmental tobacco smoke (Z77.22)
- exposure to tobacco smoke in the perinatal period (P96.81)
- history of tobacco dependence (Z87.891)

- tobacco dependence (F17.-)
- tobacco use (Z72.0)
Other codes that can never be billed with K11
These codes carry an Excludes1 note pointing at K11. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K11 alone.
- K11.21Acute sialoadenitis
Risk adjustment
K11 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 K11
