Excludes1 inherited from the categories above S05.02XS
These are not written on S05.02XS, but they bind it: a note on a category applies to every code beneath it. Billing S05.02XS with anything listed here is a denial.
Excludes2 inherited from the categories above S05.02XS
Also inherited, and the opposite of Excludes1: these conditions are not part of S05.02XS, but a patient can have both, so you may code both.
Other codes that can never be billed with S05.02XS
These codes carry an Excludes1 note pointing at S05.02XS. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S05.02XS alone.
Risk adjustment
S05.02XS 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
S05.02XS is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
