Use additional code

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)
  • occupational exposure to environmental tobacco smoke (Z57.31)
  • 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.

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

10 child codes. Green means billable.
