ICD-10 Code G81.13 – Spastic hemiplegia affecting right nondominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G81.13 – Spastic hemiplegia affecting right nondominant side
What it is
G81.13 identifies spastic hemiplegia on the right side in a patient whose right side is nondominant. It describes a persistent one-sided paralysis or severe weakness with increased muscle tone.
Clinical signs
Typical findings include stiffness, increased reflexes, and limited voluntary movement on the right side. Clinical features vary; refer to documentation for the exact neurologic deficits and dominance status.
When to use this code
Use this code when the provider documents spastic hemiplegia affecting the right nondominant side and the record supports laterality and dominance. It is appropriate for chronic neurologic deficits after stroke or other brain injury when the right side is specifically described. Check documentation if dominance is not stated.
Do not use for
Do not use it for generalized weakness, flaccid hemiplegia, or hemiparesis without spasticity. Avoid this code if the affected side, dominance, or diagnosis is documented differently.
Coding tip
Verify both laterality and dominance in the note before assigning G81.13.
