Complete lesion of L4 level of lumbar spinal cord, subs

This code signifies a complete transection or severe damage to the L4 segment of the lumbar spinal cord, resulting in a total loss of motor and sensory function below that level. It indicates a permanent and irreversible injury to the spinal cord at the L4 vertebral level.

Apply this code for follow-up visits, rehabilitation encounters, or any subsequent care related to a previously diagnosed complete L4 spinal cord lesion. This includes ongoing management of complications, physical therapy, or medication refills after the initial injury has been addressed.

• Ensure documentation clearly states "complete lesion" and specifies the L4 level.
• Verify the encounter is for subsequent care, not the initial injury (which would use an 'A' or 'D' for initial encounter).
• Distinguish from incomplete lesions, which have different code assignments.
