ICD-10 Code I62.03 – Nontraumatic chronic subdural hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I62.03 – Nontraumatic chronic subdural hemorrhage
What it is
I62.03 identifies a chronic subdural bleed that is not caused by trauma. It usually refers to an older collection of blood between the dura and brain that persists over time.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include headache, confusion, gait changes, weakness, or other neurologic deficits, especially when imaging confirms a chronic subdural collection.
When to use this code
Use I62.03 when the provider documents a chronic subdural hemorrhage and states it is nontraumatic. This code fits cases confirmed by CT or MRI and described as chronic, old, or persistent. If the record does not clearly exclude trauma, check documentation.
Do not use for
Do not use this code for acute subdural hemorrhage, traumatic head injury, or unspecified intracranial bleeding. If the chart only says “subdural hematoma” without chronic or nontraumatic detail, check documentation.
Coding tip
Confirm both chronicity and nontraumatic cause in the provider note before assigning I62.03.
