ICD-10 Code I69.09 – Other sequelae of nontraumatic subarachnoid hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.09 – Other sequelae of nontraumatic subarachnoid hemorrhage
What it is
This code identifies late effects that remain after a nontraumatic subarachnoid hemorrhage. Use it when the acute bleed is no longer active, but residual problems are still being documented.
Clinical signs
Clinical features vary; refer to documentation. Common sequelae may include persistent neurologic deficits, cognitive changes, or other lasting impairment attributed to the prior hemorrhage.
When to use this code
Use I69.09 when the record clearly states a residual condition from a previous nontraumatic subarachnoid hemorrhage. The acute event should be past, and the current encounter should focus on the sequela, not active bleeding.
Assign it when the provider links the ongoing deficit to the prior hemorrhage. If the documentation only mentions a history of hemorrhage without a residual effect, check documentation before coding.
Do not use for
Do not use this code for an acute subarachnoid hemorrhage or for sequelae of traumatic brain injury. Do not use it if the chart does not identify a residual condition.
Coding tip
Code the sequela and any associated current deficit together only when the provider documents the causal relationship.
