ICD-10 Code G43.83 – Menstrual migraine, intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G43.83 – Menstrual migraine, intractable
What it is
G43.83 identifies a migraine disorder linked to the menstrual cycle that is documented as intractable, meaning it is difficult to control or does not respond well to usual management. Use it only when the record clearly ties the migraine to menstruation.
Clinical signs
Typical migraine features may include unilateral throbbing headache, nausea, vomiting, and light or sound sensitivity. Clinical features vary; refer to documentation for menstrual timing and evidence that the attacks are intractable.
When to use this code
Use this code when the provider documents menstrual migraine and states it is intractable, refractory, or poorly controlled. It is appropriate when the chart links attacks to the menstrual period and supports the diagnosis clearly. Check documentation if the menstrual association is implied rather than stated.
Do not use for
Do not use this code for ordinary migraine without menstrual association or without documentation of intractability. If the note describes headache only, or the type is uncertain, check documentation before coding.
Coding tip
Confirm both elements in the note: menstrual association and intractable status.
