ICD-10 Code I69.959 – Hemiplegia and hemiparesis following unspecified cerebrovascular disease affecting unspecified side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.959 – Hemiplegia and hemiparesis following unspecified cerebrovascular disease affecting unspecified side
What it is
This code identifies lingering weakness or paralysis on one side of the body after a cerebrovascular disease, when the side affected is not documented. Use it for residual deficits, not the acute stroke event.
Clinical signs
Typical findings include unilateral weakness, reduced motor control, or partial paralysis after a prior cerebrovascular event. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record links hemiplegia or hemiparesis to a previous unspecified cerebrovascular disease and does not specify right or left side. It fits follow-up visits, rehabilitation, or chronic problem lists when the residual deficit remains active. Check documentation for the most precise laterality and cause.
Do not use for
Do not use it for acute stroke, transient ischemic attack, or weakness without a documented cerebrovascular cause. If the side is documented, choose a more specific code.
Coding tip
Assign the code only when the provider clearly documents a residual hemiplegia or hemiparesis after cerebrovascular disease.
