ICD-10 Code G44.22 – Chronic tension-type headache (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G44.22 – Chronic tension-type headache
What it is
G44.22 identifies chronic tension-type headache, a primary headache disorder with frequent, recurring head pain. Use it when the record documents a tension-type pattern that is chronic rather than occasional.
Clinical signs
Typical features include bilateral, pressing or tightening head pain that is mild to moderate and not worsened by routine activity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic tension-type headache or clearly describes a long-standing tension-type headache pattern. It fits recurring headaches that meet the chronic diagnosis in the chart. If the record is vague, check documentation before assigning the code.
Do not use for
Do not use G44.22 for migraine, cluster headache, or headache due to another cause. If the headache is secondary to trauma, infection, or another condition, code the documented underlying diagnosis instead.
Coding tip
Confirm that “chronic” is stated or clearly supported in the note before selecting G44.22.
