ICD-10 Code I69.833 – Monoplegia of upper limb following other cerebrovascular disease affecting right non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.833 – Monoplegia of upper limb following other cerebrovascular disease affecting right non-dominant side
What it is
This code identifies paralysis or severe weakness limited to one upper limb that results from a prior cerebrovascular disease other than stroke. It specifies the right side and that the affected side is non-dominant.
Clinical signs
Patients typically have marked loss of voluntary movement or strength in the right arm, with preserved function in the other limbs. Clinical features vary; refer to documentation for the neurologic deficit and dominance status.
When to use this code
Use I69.833 when the record clearly links current right upper-limb monoplegia to a previous cerebrovascular condition. You should also confirm that the right side is documented as non-dominant. If the cause, laterality, or dominance is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for acute stroke, transient weakness, or paralysis from another cause. It is also inappropriate if the deficit is not specifically documented as affecting the right non-dominant upper limb.
Coding tip
Verify both laterality and dominance in the chart, because this code is highly specific and depends on both details.
