Excludes1 inherited from the categories above S78.911D
These are not written on S78.911D, but they bind it: a note on a category applies to every code beneath it. Billing S78.911D with anything listed here is a denial.
Other codes that can never be billed with S78.911D
These codes carry an Excludes1 note pointing at S78.911D. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S78.911D alone.
Risk adjustment
S78.911D 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.
