ICD-10 Code G83.34 – Monoplegia, unspecified affecting left nondominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G83.34 – Monoplegia, unspecified affecting left nondominant side
What it is
G83.34 identifies paralysis limited to one limb on the left nondominant side when the cause or exact type is not specified. Use it when documentation states monoplegia without further detail.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include marked weakness or paralysis in one left-sided limb, with reduced voluntary movement and functional impairment.
When to use this code
Use this code when the record documents monoplegia affecting the left nondominant side and does not name a specific cause. It may fit post-stroke, neurologic, or injury-related notes only if the provider records monoplegia and laterality clearly. Check documentation for dominance and any more specific diagnosis.
Do not use for
Do not use this code if the note describes hemiplegia, generalized weakness, or paralysis affecting more than one limb. If the affected side, dominance, or cause is specified more precisely, choose the more exact code.
Coding tip
Verify both laterality and hand dominance in the chart before assigning G83.34.
