inhalant use, unspecified (F18.9-)

Other codes that can never be billed with F18.2

F18.9Inhalant use, unspecified

F18.2 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 F18.2

8 child codes. Green means billable.
