About coding gallbladder perforation
The ICD-10-CM code for gallbladder perforation is K82.2 (Perforation of gallbladder).
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.
Don't confuse with (Excludes1 for K82.2)
