ICD-10 Code I69.953 – Hemiplegia and hemiparesis following unspecified cerebrovascular disease affecting right non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.953 – Hemiplegia and hemiparesis following unspecified cerebrovascular disease affecting right non-dominant side
What it is
This code identifies persistent weakness or paralysis on the right side after an unspecified cerebrovascular disease event. Use it when the right side is the non-dominant side and the deficit is documented as a sequela.
Clinical signs
Typical findings include reduced strength, impaired movement, or loss of coordination on the right side. Clinical features vary; refer to documentation for whether the deficit is hemiplegia or hemiparesis and for dominant-side status.
When to use this code
Use I69.953 when the record clearly links the current right-sided motor deficit to a prior unspecified cerebrovascular disease. You should see documentation that the weakness is residual, not acute, and that the right side is non-dominant. Check documentation if laterality or dominance is unclear.
Do not use for
Do not use this code for an acute stroke, transient neurologic symptoms, or weakness without a documented cerebrovascular cause. Do not assign it if the affected side or dominant side is not specified.
Coding tip
Confirm the sequela relationship and laterality in the note before coding.
