Other codes that can never be billed with K75.81

These codes carry an Excludes1 note pointing at K75.81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K75.81 alone.

K76.0Fatty (change of) liver, not elsewhere classified

Risk adjustment

K75.81 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

K75.81 is named in 16 Medicare coverage policies — 16 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
