ICD-10 Code I62.0 – Nontraumatic subdural hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I62.0 – Nontraumatic subdural hemorrhage
What it is
I62.0 identifies bleeding into the subdural space that is not caused by trauma. It usually reflects an intracranial hemorrhage documented as spontaneous, nontraumatic, or due to an underlying medical condition.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include headache, altered mental status, focal neurologic deficits, or decreased consciousness, depending on the bleed’s size and location.
When to use this code
Use I62.0 when the provider documents a subdural hemorrhage and specifically states it is nontraumatic or spontaneous. It also fits when the record clearly excludes injury as the cause.
Code this only when the diagnosis is confirmed or treated as the active condition. If the note suggests trauma, use the appropriate traumatic head injury code instead.
Do not use for
Do not use I62.0 for traumatic subdural hemorrhage or for other intracranial bleeds such as subarachnoid or intracerebral hemorrhage. Check documentation if the cause is unclear.
Coding tip
Look for explicit provider wording like “nontraumatic” or “spontaneous” before assigning I62.0.
