Other diseases of gallbladder (K82)

The ICD-10 codes under K82 categorize various other diseases of the gallbladder beyond common gallstone conditions. These codes are used to identify specific gallbladder issues such as obstruction, hydrops, perforation, fistulas, cholesterolosis, and other specified disorders when coding medical records or claims.

The ICD-10 code for obstruction of gallbladder (K82.0) covers conditions like biliary strictures and stenosis affecting bile or cystic ducts, often referred to as strictures or occlusions. K82.1 captures hydrops of the gallbladder, also known as gallbladder cysts or mucoceles. For gallbladder perforations or ruptures, including injuries to bile ducts, K82.2 is applied. Fistulas connecting the gallbladder to other digestive organs; such as cholecystogastric or cholecystoduodenal fistulas; are coded as K82.3. Cholesterol-related changes, including cholesterol polyps, fall under K82.4. Various other less common or specified gallbladder conditions, such as adhesions, hypertrophy, and gallbladder masses, are encompassed by K82.8. Unspecified gallbladder diseases, sometimes noted as gallbladder pain or general problems, are captured by K82.9. Additionally, complications of cholecystitis like gangrene or perforation are coded with subcategories of K82.A. These detailed distinctions help healthcare providers and coders accurately document complex gallbladder conditions for appropriate clinical and billing purposes.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • nonvisualization of gallbladder R93.2
  • postcholecystectomy syndrome K91.5

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Biliary Dyskinesia

A motility disorder characterized by biliary COLIC, absence of GALLSTONES, and an abnormal GALLBLADDER ejection fraction. It is caused by gallbladder dyskinesia and/or SPHINCTER OF ODDI DYSFUNCTION.

Gastric Fistula
