ICD-10 Code G44.201 – Tension-type headache, unspecified, intractable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G44.201 – Tension-type headache, unspecified, intractable
What it is
This code identifies a tension-type headache that is not otherwise specified and is described as intractable, meaning it is difficult to control or does not respond as expected. Use it when the record supports a tension-type pattern but does not name a more specific subtype.
Clinical signs
Typical features include a bilateral, pressing or tightening headache with mild to moderate intensity and no prominent migraine symptoms. Clinical features vary; refer to documentation.
When to use this code
Use G44.201 when the provider documents tension-type headache, unspecified, and also states it is intractable or refractory. It may fit follow-up visits where the headache persists despite prior management. You should code from the documented diagnosis, not from suspected headache type alone.
Do not use for
Do not use this code for migraine, cluster headache, or other clearly specified headache disorders. If the record does not support intractability or the type is better defined, check documentation.
Coding tip
Confirm both elements: unspecified tension-type headache and intractable status, because missing either detail can change the code.
