ICD-10 Code I62.02 – Nontraumatic subacute subdural hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I62.02 – Nontraumatic subacute subdural hemorrhage
What it is
I62.02 identifies a subdural hemorrhage that is not caused by trauma and is described as subacute. It means blood has collected between the dura and brain coverings, with timing suggesting an intermediate stage.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include headache, altered mental status, focal neurologic deficits, or decreased responsiveness, but the chart should confirm the hemorrhage type and subacute timing.
When to use this code
Use I62.02 when the provider documents a nontraumatic subdural hemorrhage and specifies that it is subacute. This code fits spontaneous or medically caused bleeding, not an injury-related bleed. If the note only says “subdural hemorrhage” or timing is unclear, check documentation before coding.
Do not use for
Do not use this code for traumatic subdural hemorrhage or for chronic or acute subdural hemorrhage. If the record does not clearly support nontraumatic and subacute, do not assume this code.
Coding tip
Confirm both the cause and the timing in the provider note before assigning I62.02.
