ICD-10 Code G81.93 – Hemiplegia, unspecified affecting right nondominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G81.93 – Hemiplegia, unspecified affecting right nondominant side
What it is
Use this code for hemiplegia affecting the right side when the record does not specify the cause or type. The patient’s right side is described as nondominant, so document that laterality clearly.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include paralysis or near-paralysis on the right side, with reduced voluntary movement, weakness, and impaired function of the arm, leg, or both.
When to use this code
Use G81.93 when the provider documents right-sided hemiplegia and identifies the right side as nondominant, but does not specify a more detailed subtype. It may appear in stroke, neurologic injury, or other conditions causing unilateral paralysis. Check documentation if dominance is not stated.
Do not use for
Do not use this code for generalized weakness, monoplegia, or hemiparesis without paralysis. If the record identifies a different side, dominance, or a more specific hemiplegia code, choose the documented diagnosis instead.
Coding tip
Confirm both laterality and dominance in the note before assigning G81.93.
