Complete lesion at C8 level of cervical spinal cord, init

This diagnosis code signifies a total transection or severe damage to the spinal cord at the C8 vertebral level, resulting in a complete loss of motor and sensory function below that point. It indicates the initial phase of treatment for this specific type of cervical spinal cord injury.

Apply this code for patients presenting with a newly diagnosed, complete spinal cord injury affecting the C8 dermatome and myotome. Documentation must clearly state "complete lesion" and specify the C8 level, often confirmed by neurological examination findings such as absent sensation and motor function below C8.

• Ensure documentation explicitly states "complete lesion" and the specific C8 level; "incomplete" lesions require different codes.
• The 7th character 'A' indicates an initial encounter for active treatment of the injury, not subsequent care.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
