ICD-10 Code G82.50 – Quadriplegia, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G82.50 – Quadriplegia, unspecified
What it is
G82.50 identifies quadriplegia, meaning paralysis affecting all four limbs. Use this code when the record does not specify whether the condition is complete, incomplete, or due to a particular cause.
Clinical signs
Typical findings include severe weakness or loss of movement in both arms and both legs. Clinical features vary; refer to documentation for level of impairment, sensory findings, and whether the paralysis is complete or incomplete.
When to use this code
Use G82.50 when the provider documents quadriplegia but gives no further detail. It is appropriate for problem lists, discharge summaries, or encounters where the paralysis is confirmed but not otherwise characterized. Check documentation if another neurologic condition or injury explains the paralysis.
Do not use for
Do not use this code for hemiplegia, paraplegia, or generalized weakness without documented quadriplegia. If the cause or completeness is specified, choose the more specific code instead.
Coding tip
Look for terms like “complete,” “incomplete,” or an underlying injury, because those details may change the code selection.
