ICD-10 Code K80.47 – Calculus of bile duct with acute and chronic cholecystitis with obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.47 – Calculus of bile duct with acute and chronic cholecystitis with obstruction
What it is
K80.47 identifies gallstones in the bile duct with both acute and chronic inflammation of the gallbladder, plus obstruction. Use it when documentation clearly links these conditions together.
Clinical signs
Typical findings include biliary pain, right upper quadrant tenderness, and evidence of gallstone-related obstruction. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states calculus of the bile duct and acute and chronic cholecystitis with obstruction in the same encounter. It fits when the provider documents obstructive gallstone disease affecting the gallbladder and bile duct. Check documentation if the acute, chronic, or obstructive elements are not clearly stated.
Do not use for
Do not use K80.47 if the chart only shows gallstones without obstruction or without both acute and chronic cholecystitis. Do not assume the combination when documentation is incomplete.
Coding tip
Code the full documented combination only when all elements are explicitly linked by the provider.
