ICD-10 Code G82.52 – Quadriplegia, C1-C4 incomplete (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G82.52 – Quadriplegia, C1-C4 incomplete
What it is
G82.52 identifies incomplete quadriplegia affecting the C1-C4 spinal cord level. Use it when injury or disease causes partial loss of motor and/or sensory function in all four limbs below the cervical level.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include weakness or paralysis in both arms and legs, reduced sensation below the injury level, and possible impaired breathing if the high cervical cord is involved.
When to use this code
Use this code when the record clearly states incomplete quadriplegia at C1-C4. It fits traumatic and nontraumatic causes if the provider documents the diagnosis. If the note only says tetraparesis, quadriparesis, or spinal cord injury, check documentation before assigning G82.52.
Do not use for
Do not use this code for complete quadriplegia or for paralysis limited to one limb or one side of the body. If the level is different or the term is uncertain, check documentation.
Coding tip
Confirm both the completeness and the cervical level in the provider note before coding G82.52.
