Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Any condition listed in K80.5 with cholecystitis (with cholangitis)
Other codes that can never be billed with K80.4
These codes carry an Excludes1 note pointing at K80.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K80.4 alone.
- K83.0Cholangitis
Risk adjustment
K80.4 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 K80.4
