About coding Cholesterolosis
The ICD-10-CM code for Cholesterolosis is K82.4 (Cholesterolosis of gallbladder). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K82.4.
Within K82 (other diseases of gallbladder), K82.4 is specifically for Cholesterolosis of gallbladder. Related codes cover obstruction of gallbladder (K82.0), hydrops of gallbladder (K82.1), perforation of gallbladder (K82.2), fistula of gallbladder (K82.3), 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 K82.4 together with the conditions in its Excludes1 note: cholesterolosis of gallbladder with cholecystitis (K81.-) and cholesterolosis of gallbladder with cholelithiasis (K80.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
