ICD-10 Code G43.80 – Other migraine, not intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.80 – Other migraine, not intractable
What it is
Use this code for a migraine diagnosis that does not fit a more specific migraine subtype and is described as not intractable. It indicates the headache disorder is present, but the record does not describe refractory or difficult-to-control symptoms.
Clinical signs
Typical migraine features include recurrent headache with possible nausea, vomiting, and sensitivity to light or sound. Clinical features vary; refer to documentation.
When to use this code
Assign G43.80 when the provider documents “other migraine” and does not identify a more specific migraine type. Use it when the migraine is noted as not intractable and there is no documentation of status migrainosus or another excluded subtype.
Do not use for
Do not use this code if the record specifies a different migraine category, such as migraine with aura or chronic migraine. Check documentation if the headache diagnosis is uncertain or if the provider describes intractable migraine.
Coding tip
Match the code to the exact provider wording and confirm whether “not intractable” is documented.
