Other codes that can never be billed with W27.0

These codes carry an Excludes1 note pointing at W27.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W27.0 alone.

W31.2XXAContact with powered woodworking and forming machines, initial encounter
W31.2XXDContact with powered woodworking and forming machines, subsequent encounter

Risk adjustment

W27.0 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.
