ICD-10 Code G43.109 – Migraine with aura, not intractable, without status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.109 – Migraine with aura, not intractable, without status migrainosus
What it is
This code identifies migraine attacks that include aura, are not described as intractable, and do not meet criteria for status migrainosus. Use it when the record supports migraine with aura but not prolonged, severe, or refractory disease.
Clinical signs
Typical aura may include transient visual, sensory, or speech symptoms that precede or accompany the headache. Clinical features vary; refer to documentation for the exact aura type and migraine pattern.
When to use this code
Use this code when the provider documents migraine with aura and specifically states it is not intractable and without status migrainosus. It fits routine migraine encounters, follow-up visits, and problem list entries when the diagnosis is confirmed. Check documentation if the note only says “migraine” or does not identify aura.
Do not use for
Do not use it for migraine without aura, intractable migraine, or migraine with status migrainosus. If the documentation is unclear or conflicting, check documentation before coding.
Coding tip
Confirm both the aura and the nonintractable, non-status wording in the provider note before assigning G43.109.
