ICD-10 Code G44.209 – Tension-type headache, unspecified, not intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G44.209 – Tension-type headache, unspecified, not intractable
What it is
This code identifies a tension-type headache when the type is not further specified and the headache is not documented as intractable. Use it for a primary headache disorder described as tension-type, with no more precise subtype recorded.
Clinical signs
Typical features include a bilateral, pressing or tightening head pain that is usually mild to moderate and not worsened by routine activity. Nausea, vomiting, or focal neurologic findings are not expected; clinical features vary, so refer to documentation.
When to use this code
Use G44.209 when the provider documents tension-type headache but does not specify episodic or chronic type, and does not state that it is intractable. It also fits when the note simply says “tension headache” without more detail. If the record is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for migraine, cluster headache, or headache due to another diagnosed condition. Do not assign it when the provider documents a more specific tension-type headache code or states the headache is intractable.
Coding tip
Confirm both specificity and intractability in the note; if either is missing, G44.209 is usually the safest choice.
