ICD-10 Code I69.00 – Unspecified sequelae of nontraumatic subarachnoid hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.00 – Unspecified sequelae of nontraumatic subarachnoid hemorrhage
What it is
This code identifies late effects of a prior nontraumatic subarachnoid hemorrhage when the specific residual problem is not documented. Use it for conditions that persist after the acute bleed has resolved.
Clinical signs
Clinical features vary; refer to documentation. Residual findings may include neurologic deficits, cognitive changes, or other ongoing effects attributed to the earlier hemorrhage.
When to use this code
Use this code when the record clearly links a current condition to a past nontraumatic subarachnoid hemorrhage, but the sequela is not otherwise specified. It fits follow-up encounters for persistent aftereffects, not the acute event. If the residual deficit is documented elsewhere, code that specific sequela instead.
Do not use for
Do not use it for the initial acute subarachnoid hemorrhage or for traumatic intracranial bleeding. If the residual condition is identified, choose the more specific sequela code instead.
Coding tip
Verify that the provider documents a causal link to the prior hemorrhage and that the sequela is unspecified before assigning I69.00.
