ICD-10 Code I60.8 – Other nontraumatic subarachnoid hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I60.8 – Other nontraumatic subarachnoid hemorrhage
What it is
This code identifies a subarachnoid hemorrhage that is not caused by trauma and does not fit a more specific nontraumatic subarachnoid hemorrhage category. It means bleeding has occurred in the subarachnoid space, but the documented site or cause is classified as other.
Clinical signs
Patients may present with sudden severe headache, neck stiffness, nausea, vomiting, or altered consciousness. Clinical features vary; refer to documentation and imaging findings when available.
When to use this code
Use I60.8 when the record clearly documents a nontraumatic subarachnoid hemorrhage and the provider does not specify a more exact subarachnoid site. It is appropriate when imaging or clinical notes confirm SAH, but the chart does not support a more specific I60 category. Check documentation if the hemorrhage is traumatic, aneurysmal, or otherwise coded more specifically.
Do not use for
Do not use this code for traumatic subarachnoid hemorrhage or for nontraumatic SAH with a more specific documented site. Check documentation if the condition is better classified elsewhere.
Coding tip
Assign the most specific subarachnoid hemorrhage code available; use I60.8 only when the documentation leaves the site or subtype unspecified.
