- C
- initial encounter for open fracture type IIIA, IIIB, or IIIC
- D

- E
- subsequent encounter for open fracture type I or II with routine healing
- F
- subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
- G
- subsequent encounter for closed fracture with delayed healing
- H
- subsequent encounter for open fracture type I or II with delayed healing
- J
- subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing

Excludes1 inherited from the categories above S52.241K
These are not written on S52.241K, but they bind it: a note on a category applies to every code beneath it. Billing S52.241K with anything listed here is a denial.
Excludes2 inherited from the categories above S52.241K
Also inherited, and the opposite of Excludes1: these conditions are not part of S52.241K, but a patient can have both, so you may code both.
Other codes that can never be billed with S52.241K
These codes carry an Excludes1 note pointing at S52.241K. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S52.241K alone.
Risk adjustment
S52.241K 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.
Medicare coverage
S52.241K is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
