About ICD-10-CM I60
ICD-10-CM code I60 represents Nontraumatic subarachnoid hemorrhage. This is a non-billable header code in the Circulatory System chapter (block I60). The 2026 edition of ICD-10-CM I60 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Type 1 Excludes
Pure excludes, these codes can never be coded together with I60. The conditions are mutually exclusive (e.g., congenital vs acquired forms).

Type 2 Excludes
Not included here, the excluded code is not part of I60, but a patient may have both conditions at the same time. Both codes may be coded together when applicable.
- sequelae of subarachnoid hemorrhage (I69.0-)
Use Additional Code
When coding I60, also report these additional codes when applicable.
