ICD-10 Code G44.211 – Episodic tension-type headache, intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G44.211 – Episodic tension-type headache, intractable
What it is
Use this code for a recurring tension-type headache that does not respond adequately to usual management. It describes an episodic pattern rather than a constant daily headache.
Clinical signs
Typical features include bilateral, pressing or tightening head pain with mild to moderate intensity. Clinical features vary; refer to documentation for the headache pattern, associated symptoms, and whether the episode is considered intractable.
When to use this code
Assign G44.211 when the record clearly states episodic tension-type headache and documents that it is intractable or refractory. Use it for outpatient, emergency, or follow-up visits when the provider confirms this specific diagnosis.
If the note only says “headache” or does not specify tension-type and intractable status, check documentation before coding. You need both the headache type and the lack of response to treatment.
Do not use for
Do not use this code for migraine, cluster headache, or chronic tension-type headache. If the provider does not document intractable status, check documentation.
Coding tip
Code the most specific headache type documented, and verify that “intractable” is explicitly stated before assigning G44.211.
