ICD-10 Code I60.2 – Nontraumatic subarachnoid hemorrhage from anterior communicating artery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I60.2 – Nontraumatic subarachnoid hemorrhage from anterior communicating artery
What it is
This code identifies bleeding into the subarachnoid space that is not caused by trauma and is traced to the anterior communicating artery. Use it when documentation specifies this artery as the source.
Clinical signs
Typical findings include sudden severe headache, neck stiffness, nausea, vomiting, photophobia, or loss of consciousness. Clinical features vary; refer to documentation, imaging, and provider assessment for the confirmed vessel source.
When to use this code
Use I60.2 when the provider documents a nontraumatic subarachnoid hemorrhage from the anterior communicating artery, such as after CT, CTA, or angiographic confirmation. It also fits when the chart clearly links the hemorrhage to this artery. If the source vessel is not specified, check documentation before assigning this code.
Do not use for
Do not use this code for traumatic subarachnoid hemorrhage or for hemorrhage from a different intracranial vessel. If the record only states subarachnoid hemorrhage without an artery, check documentation.
Coding tip
Code the exact artery named in the provider record; if the anterior communicating artery is not stated, do not assume I60.2.
