ICD-10 Code K80.71 – Calculus of gallbladder and bile duct without cholecystitis with obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.71 – Calculus of gallbladder and bile duct without cholecystitis with obstruction
What it is
This code identifies gallstones in the gallbladder or bile duct that are causing obstruction, without associated cholecystitis. Use it when documentation shows a stone blocking bile flow but no inflammation of the gallbladder.
Clinical signs
Typical findings include biliary colic, jaundice, or evidence of blocked bile drainage. Clinical features vary; refer to documentation, especially for imaging or operative reports confirming obstruction.
When to use this code
Use K80.71 when the record clearly states gallstones are present in the gallbladder or bile duct and obstruction is documented. It also fits cases where imaging, ERCP, or surgery confirms an obstructing calculus without cholecystitis. If the note does not specify obstruction, check documentation.
Do not use for
Do not use this code for gallstones without obstruction or for calculous cholecystitis. If the obstruction site or presence of inflammation is unclear, check documentation before assigning the code.
Coding tip
Code from the most specific provider statement, and verify that “without cholecystitis” and “with obstruction” are both documented.
