Other codes that can never be billed with K83.09
These codes carry an Excludes1 note pointing at K83.09. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K83.09 alone.

Risk adjustment
K83.09 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 68 Cholangitis and Obstruction of Bile Duct Without Gallstones0.388 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
