ICD-10 Code I62.00 – Nontraumatic subdural hemorrhage, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I62.00 – Nontraumatic subdural hemorrhage, unspecified
What it is
I62.00 identifies a subdural hemorrhage that is not caused by trauma, with no further detail on the side or exact type. Use it when documentation confirms a spontaneous or nontraumatic subdural bleed but remains unspecified.
Clinical signs
Clinical features vary; refer to documentation. Patients may present with headache, altered mental status, focal neurologic deficits, or decreased consciousness, but the record should support a nontraumatic subdural hemorrhage diagnosis.
When to use this code
Use I62.00 when the provider documents a nontraumatic subdural hemorrhage and does not specify laterality or more precise subtype. It is appropriate for imaging-confirmed subdural bleeding without a traumatic cause. If the note gives a more specific code, use that instead.
Do not use for
Do not use this code for traumatic subdural hematoma or for subdural hemorrhage with a documented cause that belongs in another category. Check documentation if the record is unclear or if another intracranial bleed is identified.
Coding tip
Code to the highest specificity available, and query for laterality or etiology when the documentation is incomplete.
