ICD-10 Code I69.834 – Monoplegia of upper limb following other cerebrovascular disease affecting left non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.834 – Monoplegia of upper limb following other cerebrovascular disease affecting left non-dominant side
What it is
This code identifies one-sided paralysis or severe weakness of the left upper limb that results from a prior cerebrovascular disease other than stroke. It indicates a residual neurologic deficit, not an active event.
Clinical signs
You may see marked loss of voluntary movement, abnormal tone, or limited functional use of the left arm and hand. Clinical features vary; refer to documentation for the specific neurologic deficit and dominance status.
When to use this code
Use I69.834 when the record links left upper-limb monoplegia to a previous cerebrovascular disease, and the affected side is documented as non-dominant. This is appropriate for residual weakness, paralysis, or poor arm control after the cerebrovascular condition has stabilized. Check documentation if the laterality or dominance is unclear.
Do not use for
Do not use this code for acute stroke or for weakness without a documented cerebrovascular cause. If the deficit is from another neurologic, traumatic, or musculoskeletal condition, choose the code supported by documentation.
Coding tip
Confirm both laterality and dominance in the chart before assigning this code.
