ICD-10 Code G81.04 – Flaccid hemiplegia affecting left nondominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G81.04 – Flaccid hemiplegia affecting left nondominant side
What it is
G81.04 identifies flaccid hemiplegia affecting the left side in a patient whose left side is not the dominant side. It describes paralysis with decreased muscle tone, not spastic weakness.
Clinical signs
Typical findings include marked weakness or paralysis of the left arm and leg with low tone and reduced voluntary movement. Clinical features vary; refer to documentation for laterality and dominance.
When to use this code
Use this code when the record clearly states flaccid hemiplegia and specifies the left nondominant side. You should also use it when the provider documents left-sided hemiplegia with flaccidity and notes the side is nondominant. Check documentation if dominance or laterality is unclear.
Do not use for
Do not use this code for spastic hemiplegia, generalized weakness, or hemiparesis without paralysis. Do not assign it if the chart does not support left-sided, nondominant involvement.
Coding tip
Confirm both laterality and dominance in the note before assigning G81.04.
