K82.2Perforation of gallbladder

K82.2 is the ICD-10-CM diagnosis code for perforation of gallbladder. It belongs to category K82 (other diseases of gallbladder), block K80-K87 (disorders of gallbladder, biliary tract and pancreas) and chapter 11 (diseases of the digestive system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within K82 (other diseases of gallbladder), K82.2 is specifically for perforation of gallbladder. Related codes cover obstruction of gallbladder (K82.0), hydrops of gallbladder (K82.1), fistula of gallbladder (K82.3), Cholesterolosis of gallbladder (K82.4), other specified diseases of gallbladder (K82.8), disease of gallbladder, unspecified (K82.9) and disorders of gallbladder in diseases classified elsewhere (K82.A).

Don't report K82.2 together with the conditions in its Excludes1 note: Perforation of gallbladder in cholecystitis (K82.A2).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 575.4 (perforation of gallbladder).
