ICD-10 Code K82.4 – Cholesterolosis of gallbladder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K82.4 – Cholesterolosis of gallbladder
What it is
K82.4 identifies cholesterolosis of the gallbladder, a condition in which cholesterol is deposited in the gallbladder lining. It is often found incidentally during imaging, surgery, or pathology.
Clinical signs
Clinical features vary; refer to documentation. Some patients have no symptoms, while others may have nonspecific right upper quadrant discomfort or findings noted on ultrasound or operative report.
When to use this code
Use K82.4 when the provider documents cholesterolosis of the gallbladder as the diagnosis. It may appear as an incidental finding, a radiologic impression, or a pathology result after cholecystectomy. Code only when the condition is clearly stated in the record.
Do not use for
Do not use this code for gallstones, acute cholecystitis, or general gallbladder pain without documented cholesterolosis. Check documentation if the record only mentions a polyp or other gallbladder abnormality.
Coding tip
If the note says “cholesterolosis” without further detail, code K82.4 and avoid substituting a gallstone or polyp code.
