ICD-10 Code G43.909: Migraine, unspecified, not intractable, without status migrainosus
Diseases of the nervous system
ICD-10 code G43.909 identifies unspecified migraine that is not intractable and without status migrainosus.
Coding guidance
The G43 category classifies migraine by type: with and without aura, hemiplegic, chronic and others.
Each type further specifies whether the migraine is intractable and whether status migrainosus is present.
G43.909 is the least specific option and should be replaced when documentation allows.
Documentation and specificity notes
- Document migraine type, aura presence, intractability and frequency for specific coding.
- Chronic migraine (G43.7-) may support different treatment authorization.
- Specificity supports prior authorization for migraine-specific therapies.
