ICD-10 Code G43.809 – Other migraine, not intractable, without status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.809 – Other migraine, not intractable, without status migrainosus
What it is
This code identifies a migraine diagnosis that does not meet a more specific migraine subtype. It also means the migraine is not described as intractable and there is no status migrainosus.
Clinical signs
Migraines commonly present with recurrent headache, often unilateral or throbbing, and may include nausea, light sensitivity, or sound sensitivity. Clinical features vary; refer to documentation.
When to use this code
Use G43.809 when the record documents migraine but does not specify a more exact migraine type. It is appropriate when the provider states the migraine is not intractable and there is no status migrainosus. If the note supports a more specific migraine diagnosis, code that instead.
Do not use for
Do not use this code if the migraine is documented as intractable or as status migrainosus. Also avoid it when the chart identifies a different, more specific migraine subtype.
Coding tip
Check the provider’s wording carefully and code the most specific migraine term documented.
