ICD-10 Code K82.0 – Obstruction of gallbladder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K82.0 – Obstruction of gallbladder
What it is
Obstruction of the gallbladder means something is blocking normal drainage from the gallbladder. This code describes the obstruction itself, not the cause unless documentation identifies it.
Clinical signs
Clinical features vary; refer to documentation. Patients may have right upper quadrant pain, nausea, vomiting, or imaging evidence of impaired gallbladder outflow.
When to use this code
Use K82.0 when the record clearly documents gallbladder obstruction, such as blockage from a stone, stricture, or other specified cause. You may also use it when imaging or operative findings confirm obstruction and the provider links it to the gallbladder. Check documentation if the cause is not stated.
Do not use for
Do not use this code for general biliary obstruction, gallstones without obstruction, or cholecystitis unless the provider documents gallbladder obstruction. If the note only says “biliary obstruction,” verify the anatomic site.
Coding tip
Assign the code only when the chart clearly identifies gallbladder obstruction; capture the documented cause with additional codes when supported.
