ICD-10 Code K82.A – Disorders of gallbladder in diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K82.A – Disorders of gallbladder in diseases classified elsewhere
What it is
K82.A identifies gallbladder disorders that are caused by another underlying disease. Use it when the gallbladder problem is documented as secondary to a separate condition, rather than as a primary gallbladder diagnosis.
Clinical signs
Clinical features vary; refer to documentation. The record should show a gallbladder disorder linked to another disease process, with the causal relationship clearly stated or implied by the provider.
When to use this code
Use K82.A when the clinician documents a gallbladder disorder “in diseases classified elsewhere” or otherwise ties it to an underlying condition. Make sure the underlying disease is also coded when required. If the note does not establish the relationship, check documentation before assigning this code.
Do not use for
Do not use this code for primary gallbladder disorders without an underlying cause, or when the chart only mentions gallbladder symptoms. If the cause is unclear, check documentation.
Coding tip
Confirm the provider’s wording for causation and code the underlying condition first when the guidelines require it.
