About ICD-10-CM K83.0

Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Type 1 Excludes
Pure excludes, these codes can never be coded together with K83.0. The conditions are mutually exclusive (e.g., congenital vs acquired forms).
- cholangitic liver abscess (K75.0)

Type 2 Excludes
Not included here, the excluded code is not part of K83.0, but a patient may have both conditions at the same time. Both codes may be coded together when applicable.
- chronic nonsuppurative destructive cholangitis (K74.3)
- primary biliary cholangitis (K74.3)
- primary biliary cirrhosis (K74.3)
