ICD-10 Code G43.D1 – Abdominal migraine, intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.D1 – Abdominal migraine, intractable
What it is
G43.D1 identifies abdominal migraine that is difficult to control or does not respond well to usual management. It refers to recurrent abdominal pain episodes linked to a migraine disorder, not a primary gastrointestinal disease.
Clinical signs
Typical features include repeated attacks of midline abdominal pain, nausea, vomiting, pallor, or loss of appetite. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents abdominal migraine and states it is intractable, refractory, or poorly controlled. You should also use it when the provider clearly links the abdominal pain episodes to migraine and notes failure of standard measures. Check documentation if the chart is unclear.
Do not use for
Do not use this code for nonspecific abdominal pain, gastroenteritis, or other digestive disorders without a documented migraine diagnosis. Do not assume intractable status unless the provider states it.
Coding tip
Confirm both the migraine-related diagnosis and the intractable designation in the provider note before assigning G43.D1.
