I60.8 — Other nontraumatic subarachnoid hemorrhage
I60.8 is a billable, specific ICD-10-CM code for other nontraumatic subarachnoid hemorrhage. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Meningeal hemorrhage
- Rupture of cerebral arteriovenous malformation
Other codes that can never be billed with I60.8
These codes carry an Excludes1 note pointing at I60.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I60.8 alone.
- Q28Other congenital malformations of circulatory system
Risk adjustment
I60.8 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 248 Intracranial Hemorrhage0.239 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
Medicare coverage
I60.8 is named in 28 Medicare coverage policies — 28 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

- A52992Billing and Coding: Non-Invasive Cerebrovascular Arterial Studies
