ICD-10 Code I62.01 – Nontraumatic acute subdural hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I62.01 – Nontraumatic acute subdural hemorrhage
What it is
I62.01 identifies an acute subdural hemorrhage that is not caused by trauma. It means there is recent bleeding between the dura and the brain, documented as nontraumatic.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe sudden neurologic change, headache, confusion, decreased level of consciousness, or focal deficits, with imaging confirming an acute subdural bleed.
When to use this code
Use I62.01 when the provider documents an acute subdural hemorrhage and specifically states it is nontraumatic. The diagnosis should be supported by imaging or clear clinical documentation. If the cause is unclear, check documentation before coding.
Do not use for
Do not use this code for traumatic subdural hemorrhage or for chronic subdural collections. If the chart does not clearly state nontraumatic acute bleeding, verify the diagnosis first.
Coding tip
Code the documented etiology and acuity carefully; if either is missing, check documentation before assigning I62.01.
