ICD-10-CM 2027
ICD-10 code for migraine
Confirmed by the official ICD-10-CM index entry “headache › migraine (type)”. Page updated September 29, 2026.
About coding migraine
The ICD-10-CM code for migraine is G43.909 (Migraine, unspecified, not intractable, without status migrainosus). The official index lists 47 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G43.909.
Within G43.90, choose G43.909 (without status migrainosus) only when documentation doesn't support a more specific option: with status migrainosus (G43.901).
Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
