Other codes that can never be billed with K92.0
These codes carry an Excludes1 note pointing at K92.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K92.0 alone.
- R11Nausea and vomiting
Risk adjustment
K92.0 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
K92.0 is named in 7 Medicare coverage policies — 7 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
