ICD-10 Code G80.1 – Spastic diplegic cerebral palsy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G80.1 – Spastic diplegic cerebral palsy
What it is
G80.1 identifies spastic diplegic cerebral palsy, a nonprogressive neurologic disorder that mainly affects muscle tone and movement. It usually involves the legs more than the arms.
Clinical signs
Common findings include increased muscle tone, stiffness, and impaired gait, often with scissoring or toe-walking. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents spastic diplegic cerebral palsy as the diagnosis. It fits encounters for ongoing management, functional assessment, or evaluation of mobility problems linked to this specific CP subtype.
Do not use for
Do not use G80.1 for other cerebral palsy types, such as hemiplegic or quadriplegic forms. Also avoid it when the chart only says “cerebral palsy” without the diplegic spastic subtype; check documentation.
Coding tip
Code the documented subtype exactly; if the subtype is not specified, you should not assume G80.1.
