ICD-10 Code K83.4 – Spasm of sphincter of Oddi (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K83.4 – Spasm of sphincter of Oddi
What it is
K83.4 identifies a functional spasm of the sphincter of Oddi, the muscle that controls bile and pancreatic juice flow into the duodenum. It is used when documentation supports this specific biliary or pancreatic outflow disorder.
Clinical signs
Typical documentation may note episodic right upper abdominal or epigastric pain, often after meals, with possible biliary-type symptoms. Clinical features vary; refer to documentation.
When to use this code
Use K83.4 when the provider documents spasm of the sphincter of Oddi, sphincter of Oddi dysfunction, or a related functional obstruction at this site. Code it only when the record clearly links the symptoms or findings to this diagnosis.
If the note describes post-procedural pain or nonspecific abdominal pain without this diagnosis, check documentation before assigning K83.4. Make sure the condition is not being used as a placeholder for an unrelated biliary disorder.
Do not use for
Do not use K83.4 for gallstones, cholangitis, pancreatitis, or unspecified abdominal pain unless the provider specifically documents sphincter of Oddi spasm. Check documentation.
Coding tip
Capture the exact provider wording; if “sphincter of Oddi dysfunction” is documented, confirm whether the intent is this code.
