ICD-10 Code I69.054 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting left non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.054 – Hemiplegia and hemiparesis following nontraumatic subarachnoid hemorrhage affecting left non-dominant side
What it is
This code identifies persistent weakness or paralysis on the left side after a nontraumatic subarachnoid hemorrhage. Use it when the left side is documented as the affected non-dominant side.
Clinical signs
Typical findings include unilateral weakness, reduced movement, spasticity, or impaired coordination after the hemorrhage. Clinical features vary; refer to documentation for the exact neurologic deficit and side.
When to use this code
Use I69.054 when the provider documents hemiplegia or hemiparesis as a late effect of a nontraumatic subarachnoid hemorrhage. The record should also specify that the left side is the non-dominant side. If dominance or laterality is unclear, check documentation before coding.
Do not use for
Do not use this code for acute subarachnoid hemorrhage or for weakness unrelated to a prior hemorrhagic stroke. Do not assign it if the affected side or dominance is not documented.
Coding tip
Link the residual weakness to the prior subarachnoid hemorrhage and verify laterality and dominance in the chart before selecting this code.
