2026 ICD-10-CM Diagnosis Code I60.32 – Nontraumatic subarachnoid hemorrhage from left posterior communicating artery
What it is
This code identifies a nontraumatic subarachnoid hemorrhage arising from the left posterior communicating artery. It indicates bleeding into the subarachnoid space that is not caused by injury.
Clinical signs
Typical findings include sudden severe headache, neck stiffness, nausea, vomiting, photophobia, or altered consciousness. Clinical features vary; refer to documentation and imaging or specialist assessment.
When to use this code
Use this code when the provider documents a nontraumatic subarachnoid hemorrhage specifically linked to the left posterior communicating artery. It is appropriate when imaging, operative findings, or discharge documentation identifies that exact source. If the artery side or source is not documented, check documentation before assigning this code.
Do not use for
Do not use this code for traumatic subarachnoid hemorrhage or for bleeds from another artery or an unspecified site. Check documentation if the record only states subarachnoid hemorrhage without laterality or vessel detail.
Coding tip
Code the documented vessel and laterality exactly as stated; if the source is unclear, query before assigning I60.32.
