ICD-10 Code G81.11 – Spastic hemiplegia affecting right dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G81.11 – Spastic hemiplegia affecting right dominant side
What it is
G81.11 identifies spastic hemiplegia, or weakness with increased muscle tone, affecting the right dominant side of the body. Use it when documentation specifies the right side and that it is the dominant side.
Clinical signs
Typical findings include unilateral weakness, stiffness, and reduced voluntary movement on the right side. Clinical features vary; refer to documentation for the documented pattern of spasticity, gait change, or upper-extremity involvement.
When to use this code
Use this code when the provider documents spastic hemiplegia involving the right dominant side, such as after stroke or another neurologic injury. It is appropriate when laterality and dominance are clearly stated in the record. Check documentation if dominance is not specified.
Do not use for
Do not use it for flaccid hemiplegia, unspecified hemiplegia, or weakness without spasticity. If the record does not confirm the right dominant side, choose the documented alternative or check documentation.
Coding tip
Verify both the side and dominance in the provider note before assigning G81.11.
