Excludes1 inherited from the categories above T74.4XXS
These are not written on T74.4XXS, but they bind it: a note on a category applies to every code beneath it. Billing T74.4XXS with anything listed here is a denial.
Other codes that can never be billed with T74.4XXS
These codes carry an Excludes1 note pointing at T74.4XXS. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T74.4XXS alone.
Risk adjustment
T74.4XXS 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
T74.4XXS is named in 8 Medicare coverage policies — 8 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
