ICD-10 Code K80.81 – Other cholelithiasis with obstruction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K80.81 – Other cholelithiasis with obstruction
What it is
This code identifies gallstones in the biliary system that are causing an obstruction, but not the specific cholelithiasis categories listed elsewhere. Use it when documentation states obstruction linked to “other” gallstones.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include biliary colic, right upper quadrant pain, jaundice, or signs of blocked bile flow when a stone obstructs the duct.
When to use this code
Use K80.81 when the record clearly documents cholelithiasis with obstruction and does not specify a more exact gallstone code. It may apply to imaging-confirmed obstruction or operative findings. You should code the documented obstruction, not assume it.
Do not use for
Do not use this code if the chart describes gallstones without obstruction, or if the condition is better captured by a more specific cholelithiasis code. Check documentation when obstruction is not explicit.
Coding tip
Verify that both gallstones and obstruction are documented together before assigning K80.81.
