ICD-10 Code I69.332 – Monoplegia of upper limb following cerebral infarction affecting left dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.332 – Monoplegia of upper limb following cerebral infarction affecting left dominant side
What it is
I69.332 identifies residual monoplegia of the upper limb after a cerebral infarction, with the left side affected and the patient documented as left dominant. Use it for a stroke-related, persistent single-limb weakness or paralysis.
Clinical signs
Typical findings include marked weakness or paralysis limited to one upper extremity after a prior ischemic stroke. Clinical features vary; refer to documentation for laterality, dominance, and whether the deficit is hemiplegic or monoplegic.
When to use this code
Use this code when the record states a residual left upper-limb monoplegia due to an old cerebral infarction. It is appropriate for follow-up visits, rehabilitation, or ongoing care when the neurologic deficit remains active. Confirm that the dominant side is documented as left.
Do not use for
Do not use it for acute stroke, transient weakness, or limb deficits from noninfarction causes. Check documentation if the chart describes hemiplegia, unspecified laterality, or a different post-stroke neurologic deficit.
Coding tip
Verify both the residual deficit and the affected dominant side in the provider note before assigning I69.332.
