Abdominal migraine, not intractable

This code identifies a type of migraine primarily characterized by recurrent episodes of abdominal pain, often accompanied by nausea, vomiting, and pallor, without a significant headache component. It is a functional gastrointestinal disorder, predominantly seen in children, and is considered a precursor to classic migraine headaches in adulthood.

Apply this code when documentation clearly states a diagnosis of abdominal migraine and specifies that the condition is not intractable. This diagnosis is typically made after excluding other organic causes of abdominal pain through diagnostic workup. Supporting documentation should include a history of episodic abdominal pain, associated symptoms, and the absence of intractable features.

• Ensure documentation explicitly states "not intractable" to use this specific code. If intractability is noted, a different code from the G43.D series would be appropriate.
• Do not confuse this with other causes of abdominal pain; a definitive diagnosis of abdominal migraine must be present.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter.
