ICD-10 Code G83.22 – Monoplegia of upper limb affecting left dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G83.22 – Monoplegia of upper limb affecting left dominant side
What it is
G83.22 identifies paralysis or severe weakness limited to the left upper limb in a dominant patient. Use it when the documentation specifically states monoplegia affecting that arm.
Clinical signs
Typical findings include marked loss of voluntary movement, reduced strength, and impaired use of one upper extremity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents monoplegia of the left arm and notes that the patient is dominant on that side. It may appear in neurologic, rehabilitation, or post-stroke records when the deficit is isolated to one upper limb. Check documentation if laterality or dominance is unclear.
Do not use for
Do not use it for generalized weakness, hemiplegia, or monoplegia of another limb. Do not assume dominance or laterality; check documentation.
Coding tip
Confirm both the affected side and dominant side in the chart before assigning G83.22.
