ICD-10 Code G83.14 – Monoplegia of lower limb affecting left nondominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G83.14 – Monoplegia of lower limb affecting left nondominant side
What it is
G83.14 identifies monoplegia affecting the left lower limb in a patient whose left side is nondominant. Use it when documentation specifies one leg is paralyzed or severely weak, and the laterality and dominance are clearly stated.
Clinical signs
Typical findings include marked weakness or paralysis limited to one lower extremity, with reduced voluntary movement and impaired gait. Clinical features vary; refer to documentation for the exact neurologic deficit and whether the condition is complete or partial.
When to use this code
Use this code when the record states monoplegia of the left leg and confirms the left side is nondominant. It is appropriate for neurologic deficits documented after stroke, injury, or another cause, as long as the provider names the condition as monoplegia.
If the note only describes generalized weakness, hemiplegia, or unspecified paresis, check documentation before assigning G83.14. You should also verify that the affected side and dominance are both recorded.
Do not use for
Do not use this code for weakness affecting both legs, the arm only, or hemiplegia. If the chart does not specify left nondominant involvement, check documentation.
Coding tip
Confirm three elements in the note: monoplegia, left lower limb, and nondominant side.
