Cervicogenic headache

This code identifies a headache disorder originating from musculoskeletal structures or neural elements of the cervical spine. Patients typically experience referred pain from the neck to the head, often unilateral, and exacerbated by neck movements or sustained postures. The headache is a secondary symptom, directly attributable to a disorder of the cervical spine.

Apply this code when documentation clearly links headache symptoms to a cervical spine pathology, such as facet joint dysfunction, discogenic pain, or muscle spasm. Supporting documentation should include physical exam findings demonstrating cervical tenderness, restricted range of motion, and/or positive provocative tests that reproduce the headache.

• Ensure physician documentation explicitly states "cervicogenic headache" or clearly describes the cervical origin of the headache.
• Do not use this code for tension-type headaches or migraines, even if neck pain is a co-occurring symptom, unless the headache is specifically attributed to the cervical spine.
• Sequence this code as the primary diagnosis when the cervicogenic headache is the reason for the encounter, followed by codes for the underlying cervical spine condition.
