ICD-10 Code G81.02 – Flaccid hemiplegia affecting left dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G81.02 – Flaccid hemiplegia affecting left dominant side
What it is
G81.02 identifies flaccid paralysis of the left dominant side of the body. Use it when the left arm and leg show reduced tone and weakness after a neurologic event or other brain lesion.
Clinical signs
Typical findings include limp muscle tone, marked weakness, and poor voluntary movement on the left dominant side. Clinical features vary; refer to documentation for laterality, dominance, and whether the hemiplegia is flaccid.
When to use this code
Use this code when the provider documents flaccid hemiplegia affecting the left dominant side, such as after stroke, brain injury, or another central nervous system disorder. Code only when laterality and dominance are clearly stated. Check documentation if the record describes hemiparesis instead of hemiplegia.
Do not use for
Do not use G81.02 for generalized weakness, spastic hemiplegia, or hemiparesis without complete paralysis. Do not assume dominance or side if the chart does not specify them.
Coding tip
Verify both the affected side and dominant-side status in the provider note before assigning G81.02.
