ICD-10 Code G43.819 – Other migraine, intractable, without status migrainosus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.819 – Other migraine, intractable, without status migrainosus
What it is
This code identifies a migraine that does not fit a more specific migraine subtype and is documented as intractable, meaning it is difficult to control. It is also documented without status migrainosus.
Clinical signs
Typical migraine features may include recurrent headache with nausea, vomiting, photophobia, or phonophobia. Clinical features vary; refer to documentation, especially when the chart states the migraine is intractable.
When to use this code
Use G43.819 when the record specifically documents other migraine and states it is intractable, but does not describe status migrainosus. This is appropriate when the provider does not identify a more specific migraine type.
Review the note for the exact migraine subtype, since more specific codes may apply if the documentation supports them. If the record is unclear, check documentation before assigning this code.
Do not use for
Do not use this code for migraine with status migrainosus or for a more specific migraine diagnosis that is documented elsewhere. Check documentation if the provider does not clearly state intractable migraine.
Coding tip
Confirm both elements in the note: “other migraine” and “intractable,” then verify that status migrainosus is not documented.
