ICD-10 Code K83.09 – Other cholangitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K83.09 – Other cholangitis
What it is
K83.09 identifies cholangitis, an inflammation of the bile ducts, when the record does not specify a more exact type. Use it for documented “other cholangitis” cases that are not better described elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Commonly, cholangitis is recognized by evidence of bile duct inflammation, often with abdominal pain, jaundice, fever, or imaging findings suggesting biliary obstruction.
When to use this code
Use K83.09 when the provider documents cholangitis but does not name a specific subtype such as primary sclerosing cholangitis or ascending cholangitis. It also fits cases labeled “other cholangitis” in the assessment or discharge summary. Check documentation if the cause or type is unclear.
Do not use for
Do not use this code when the record identifies a different, more specific biliary diagnosis. Do not assign it for nonspecific abdominal pain or jaundice without documented cholangitis.
Coding tip
Code the documented cholangitis type first; if the note is vague, query for clarification before defaulting to K83.09.
