ICD-10 Code G44.2 – Tension-type headache (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G44.2 – Tension-type headache
What it is
G44.2 identifies tension-type headache, a primary headache disorder usually described as a pressing or tightening pain. It is generally not associated with the features typical of migraine.
Clinical signs
Clinical features commonly include bilateral, mild to moderate head pain with a nonpulsating quality. Nausea, vomiting, and marked neurologic findings are typically absent; if uncertain, check documentation.
When to use this code
Use G44.2 when the provider documents tension-type headache, tension headache, or a similar diagnosis. Apply it when the record supports a primary headache without evidence of another specific headache type. If the note is vague, verify whether the headache is acute, chronic, or secondary.
Do not use for
Do not use this code for migraine, cluster headache, post-traumatic headache, or headache due to another underlying condition. If the cause is secondary or the diagnosis is not specified, check documentation.
Coding tip
Code the documented headache type exactly; do not default to G44.2 when the record names a different or secondary headache disorder.
