Calculus of gallbladder w/o cholecystitis with obstruction

This code signifies the presence of gallstones within the gallbladder that are causing a blockage, but without any associated inflammation of the gallbladder itself. The obstruction typically refers to the cystic duct or common bile duct, leading to symptoms such as biliary colic.

This code is appropriate for patients presenting with symptoms of biliary obstruction (e.g., right upper quadrant pain, jaundice) where imaging studies (ultrasound, CT, MRI) confirm the presence of cholelithiasis and evidence of obstruction, but no signs of acute cholecystitis (e.g., gallbladder wall thickening, pericholecystic fluid). Documentation should clearly state "gallstones with obstruction" and explicitly rule out cholecystitis.

• Ensure documentation clearly distinguishes between obstruction and inflammation; the absence of cholecystitis is key for this code.
• Do not use this code if cholecystitis is also present; a different code from the K80 series would be more appropriate.
• Consider sequencing with codes for associated symptoms (e.g., R10.11 for right upper quadrant pain, R17 for jaundice) if they are not integral to the diagnosis.
