G: subsequent encounter for closed fracture with delayed healing
H: subsequent encounter for open fracture type I or II with delayed healing

Other codes that can never be billed with S82.8

These codes carry an Excludes1 note pointing at S82.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S82.8 alone.

S82.3Fracture of lower end of tibia
S82.5Fracture of medial malleolus
S82.6Fracture of lateral malleolus

Risk adjustment

S82.8 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 S82.8
