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 C32

These codes carry an Excludes1 note pointing at C32. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C32 alone.

C41Malignant neoplasm of bone and articular cartilage of other and unspecified sites
C49Malignant neoplasm of other connective and soft tissue

Risk adjustment

C32 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 C32

6 child codes. Green means billable.
