ICD-10 Code I69.932 – Monoplegia of upper limb following unspecified cerebrovascular disease affecting left dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.932 – Monoplegia of upper limb following unspecified cerebrovascular disease affecting left dominant side
What it is
This code identifies weakness or paralysis limited to one upper limb after a prior cerebrovascular disease of unspecified type. It applies when the left dominant arm is affected and the condition is a late effect, not an acute stroke.
Clinical signs
Typical findings include reduced voluntary movement, abnormal tone, and impaired arm function on the left dominant side. Clinical features vary; refer to documentation for the specific neurologic deficit and whether it is residual from a previous cerebrovascular event.
When to use this code
Use I69.932 when the record clearly links the monoplegia to a past cerebrovascular disease and specifies the left dominant upper limb. You should code it for ongoing residual deficits documented after the acute event has resolved. Check documentation if laterality, dominance, or the cerebrovascular cause is unclear.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or generalized weakness without a documented cerebrovascular residual. It is also wrong if the affected side, dominance, or specific post-stroke deficit is not confirmed.
Coding tip
Verify that the provider documents both the residual monoplegia and the left dominant side before assigning this code.
