Official ICD-10-CM descriptor (FY2026)
Migraine, unspecified, not intractable, without status migrainosus
G43.909 is valid for submission on a claim — CMS flags it as a billable, specific code.
Plain-language explanation
Migraine where the record does not state the type, and which is recorded as not intractable and without status migrainosus. Those last two attributes are what the final characters of a G43 code carry.
Written by Krasyn as a general orientation to the code. It is not from CMS and is not clinical or coding advice.
