ICD-10 Code G43.D – Abdominal migraine (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.D – Abdominal migraine
What it is
G43.D identifies abdominal migraine, a migraine variant with recurrent abdominal pain rather than typical head pain. Use it for a functional, episodic syndrome when documentation supports this diagnosis.
Clinical signs
Clinical features usually include recurrent midline abdominal pain, nausea, vomiting, pallor, and symptom-free intervals. Headache may be absent during attacks; clinical features vary, so refer to documentation.
When to use this code
Use G43.D when the provider documents abdominal migraine as the diagnosis or clearly describes a migraine-pattern abdominal pain syndrome. It fits recurrent episodes with normal intervals between attacks and no better explained gastrointestinal cause. If the record is unclear, check documentation before coding.
Do not use for
Do not use this code for nonspecific abdominal pain, gastroenteritis, or other diagnosed gastrointestinal disorders. Also avoid it when the chart does not support migraine-type recurrence or the provider has not confirmed abdominal migraine.
Coding tip
Code only when abdominal migraine is explicitly documented or clearly established in the assessment; otherwise, query the provider.
