ICD-10 Code G83.11 – Monoplegia of lower limb affecting right dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G83.11 – Monoplegia of lower limb affecting right dominant side
What it is
G83.11 identifies paralysis or severe weakness limited to the right lower limb in a patient whose right side is dominant. Use it when the documentation clearly states monoplegia affecting that limb and side.
Clinical signs
Typical findings include marked loss of voluntary movement in one leg, with preserved function in the other limbs. Clinical features vary; refer to documentation for laterality, dominance, and whether the condition is complete or partial.
When to use this code
Use this code when the provider documents monoplegia of the right lower extremity and specifies that the right side is dominant. It may appear in records for stroke, neurologic injury, or other causes of one-limb paralysis. If dominance or laterality is unclear, check documentation before coding.
Do not use for
Do not use it for generalized weakness, hemiplegia, or monoplegia of a different limb or side. Do not assume dominance; if the record does not specify right dominant side, check documentation.
Coding tip
Confirm both the affected limb and dominance from the provider’s note before assigning G83.11.
