What This Code Means

Recurring episodes of abdominal pain occurring as a migraine variant that does not respond adequately to standard treatment methods.

Coding Tips

  • Document failed treatment attempts and the intractable nature of the condition
  • Distinguish from other causes of recurrent abdominal pain by confirming migraine characteristics

Clinical Significance

Abdominal migraine is a recurrent episodic condition characterized by midline abdominal pain, nausea, and vomiting, primarily affecting children but also occurring in adults. It is recognized as a migraine variant and often precedes development of typical migraine headaches later in life. Accurate coding prevents unnecessary gastrointestinal workups and directs treatment toward migraine-specific therapies.

Documentation Requirements

  • Recurrent episodes of midline abdominal pain lasting 2-72 hours
  • Associated symptoms: nausea, vomiting, anorexia, pallor
  • Symptom-free intervals between episodes (complete return to baseline health)
  • Exclusion of gastrointestinal, renal, and metabolic causes of recurrent abdominal pain
  • Family history of migraine (supports diagnosis)
  • Stereotypical pattern to episodes (similar presentation each time)
  • Intractability documentation: failed prophylactic therapy
  • At least 2 episodes meeting diagnostic criteria
