About coding biliary obstruction

The ICD-10-CM code for biliary obstruction is K83.1 (Obstruction of bile duct). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K83.1.

Within K83 (other diseases of biliary tract), K83.1 is specifically for obstruction of bile duct. Related codes cover cholangitis (K83.0), perforation of bile duct (K83.2), fistula of bile duct (K83.3), spasm of sphincter of Oddi (K83.4), biliary cyst (K83.5), other specified diseases of biliary tract (K83.8) and disease of biliary tract, unspecified (K83.9).

Don't report K83.1 together with the conditions in its Excludes1 note: congenital obstruction of bile duct (Q44.3) and obstruction of bile duct with cholelithiasis (K80.-).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
