Spasm of sphincter of Oddi

This code represents an involuntary contraction or tightening of the sphincter of Oddi, a muscular valve that controls the flow of digestive fluids (bile and pancreatic juice) into the small intestine. This spasm can lead to impaired bile and pancreatic flow, causing pain and potentially contributing to conditions like pancreatitis or cholangitis.

Use this code when documentation explicitly states "spasm of sphincter of Oddi" or "Oddi's sphincter dysfunction" (Type I or II, where spasm is the primary component). This diagnosis is often made after imaging studies (e.g., ERCP, MRCP) or manometry confirm the dysfunction.

• Differentiate from other causes of biliary obstruction or abdominal pain; documentation must specify sphincter of Oddi involvement.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or secondary if it's a contributing factor to another condition.
• Review for associated conditions such as pancreatitis or cholelithiasis, which may require additional codes.
