About coding gallbladder obstruction
The ICD-10-CM code for gallbladder obstruction is K82.0 (Obstruction of gallbladder). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K82.0.
Within K82 (other diseases of gallbladder), K82.0 is specifically for obstruction of gallbladder. Related codes cover hydrops of gallbladder (K82.1), perforation of gallbladder (K82.2), 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 K82.0 together with the conditions in its Excludes1 note: obstruction of gallbladder with cholelithiasis (K80.-).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
