Other diseases of gallbladder (K82) ICD-10-CM
The K82 code range covers other diseases of gallbladder with 11 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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.

About the K82 Code Range
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.
