Excludes1 inherited from the categories above S01.329S
These are not written on S01.329S, but they bind it: a note on a category applies to every code beneath it. Billing S01.329S with anything listed here is a denial.
Excludes2 inherited from the categories above S01.329S
Also inherited, and the opposite of Excludes1: these conditions are not part of S01.329S, but a patient can have both, so you may code both.
Other codes that can never be billed with S01.329S
These codes carry an Excludes1 note pointing at S01.329S. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S01.329S alone.

Risk adjustment
S01.329S 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
S01.329S is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
