Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- diverticulitis of both small and large intestine with perforation and abscess (K57.4-)
Other codes that can never be billed with K57.0
These codes carry an Excludes1 note pointing at K57.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K57.0 alone.
Risk adjustment
K57.0 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.
Code to one of these instead K57.0
