ICD-10 Code I69.951 – Hemiplegia and hemiparesis following unspecified cerebrovascular disease affecting right dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.951 – Hemiplegia and hemiparesis following unspecified cerebrovascular disease affecting right dominant side
What it is
This code identifies lingering weakness or paralysis of the right dominant side after a cerebrovascular disease that is not further specified. It is used for a post-stroke-type neurologic deficit when the affected side and dominance are documented.
Clinical signs
Typical findings include reduced strength, impaired movement, or partial paralysis on the right side. Clinical features vary; refer to documentation for neurologic deficits, functional limitation, and whether the dominant side is affected.
When to use this code
Use this code when the provider documents hemiplegia or hemiparesis as a residual condition after an unspecified cerebrovascular disease. The record should support right-sided involvement and confirm the patient’s right dominant side. If the cause or side is unclear, check documentation before coding.
Do not use for
Do not use it for acute stroke, transient ischemic attack, or weakness without a documented cerebrovascular cause. Do not assign it if the affected side or dominance is not supported in the chart.
Coding tip
Confirm this is a residual deficit, not an acute event, and look for explicit documentation of right dominance before assigning I69.951.
