About coding bile duct perforation
The ICD-10-CM code for bile duct perforation is K83.2 (Perforation 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 K83.2.
Within K83 (other diseases of biliary tract), K83.2 is specifically for perforation of bile duct. Related codes cover cholangitis (K83.0), obstruction of bile duct (K83.1), 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).
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.
In MS-DRG v44.0, it is part of the grouping logic for DRG 444 (Disorders of the Biliary Tract with MCC, relative weight 1.6665), DRG 445 (Disorders of the Biliary Tract with CC, relative weight 1.0872) and DRG 446 (Disorders of the Biliary Tract without CC/MCC, relative weight 0.8124), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
