About G43.D

G43.D is the ICD-10-CM diagnosis code for abdominal migraine. It belongs to category G43 (migraine), block G40-G47 (episodic and paroxysmal disorders) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within G43 (migraine), G43.D is specifically for abdominal migraine. Related codes cover without aura (G43.0), with aura (G43.1), hemiplegic migraine (G43.4), persistent migraine aura without cerebral infarction (G43.5), persistent migraine aura with cerebral infarction (G43.6), chronic migraine without aura (G43.7), other migraine (G43.8), unspecified (G43.9) and 4 more.

To report this condition, pick the subcode that matches the documentation: G43.D0 (not intractable) and G43.D1 (intractable).

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
