Headache Diagnosis Coding (ICD-10) - Veterans Affairs

VA/DoD Clinical Practice Guideline for Primary Care Management of Headache (2020)

Headache Diagnosis Coding (ICD-10)

The medical classification list for headache seen in the International Classification of Diseases, 10th Revision is used by healthcare providers to code the most specific headache diagnosis for patients. Patients may have more than one headache disorder (e.g., migraine headache and medication overuse headache). For more information about headache criteria, please see .

Intractable refers to headaches documented by the provider to be treatment resistant, treatment refractory, medically refractory, pharmacoresistant, and/or poorly controlled.

Status migrainosus refers to migraine headaches lasting more than 72 hours.
