ICD-10 Code G44.229 – Chronic tension-type headache, not intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G44.229 – Chronic tension-type headache, not intractable
What it is
Use this code for a long-lasting tension-type headache that is not described as intractable. It usually refers to recurrent, bilateral head pain without features of migraine or another secondary cause.
Clinical signs
Typical findings include a pressing or tightening headache, often mild to moderate, with no significant nausea or vomiting. Clinical features vary; refer to documentation.
When to use this code
Assign G44.229 when the provider documents chronic tension-type headache and does not state that it is intractable. Use it for ongoing headache complaints that fit a tension-type pattern and are not better explained by another diagnosis. If the record is unclear, check documentation.
Do not use for
Do not use this code for intractable tension-type headache or for migraine, cluster headache, or headache due to another condition. Check documentation when the cause or type of headache is not clearly stated.
Coding tip
Code only when the note clearly identifies chronic tension-type headache and confirms it is not intractable.
