ICD-10 Code G81.92 – Hemiplegia, unspecified affecting left dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G81.92 – Hemiplegia, unspecified affecting left dominant side
What it is
This code identifies hemiplegia, or paralysis affecting one side of the body, specifically the left dominant side. Use it when the record states the side and dominance but does not specify the cause or type.
Clinical signs
Typical findings include marked weakness or paralysis of the left arm and leg, reduced voluntary movement, and impaired function on the dominant side. Clinical features vary; refer to documentation.
When to use this code
Use G81.92 when the provider documents hemiplegia on the left dominant side and does not identify a more specific hemiplegia code. It may appear in stroke, neurologic injury, or other neurologic disorder notes. Code only what is documented; check documentation if dominance or laterality is unclear.
Do not use for
Do not use this code for generalized weakness, hemiparesis, or paralysis without documentation of hemiplegia. Do not assign it if the record does not confirm the left dominant side.
Coding tip
Verify both laterality and dominance in the provider note before assigning G81.92.
