ICD-10 Code G44.86 – Cervicogenic headache (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G44.86 – Cervicogenic headache
What it is
Cervicogenic headache is a headache that starts in the neck and is felt in the head. Use this code when documentation identifies a cervical source for the pain.
Clinical signs
Common findings include unilateral head pain, neck pain, and reduced neck motion. Clinical features vary; refer to documentation.
When to use this code
Use G44.86 when the provider documents a headache attributed to a cervical disorder or neck pathology. It may be supported by exam findings, imaging, or a clear clinical assessment linking the headache to the neck. If the note only says “headache,” check documentation.
Do not use for
Do not use this code for migraine, tension-type headache, or headache without a cervical cause. If the source is unclear, check documentation.
Coding tip
Code the cervicogenic headache only when the record clearly connects the headache to the cervical spine or neck.
