Central cord syndrome at C4, subs

This code signifies a diagnosis of central cord syndrome affecting the C4 level of the cervical spinal cord. This condition typically results from hyperextension injuries, causing damage to the central gray matter and often leading to greater motor impairment in the upper extremities than the lower extremities.

Apply this code for follow-up encounters where a patient is receiving active treatment for central cord syndrome at the C4 level, such as physical therapy, occupational therapy, or medication management. Documentation should clearly indicate the C4 level involvement and the "subsequent encounter" status, meaning the patient is still undergoing care for the acute effects of the injury.

• Ensure the documentation specifies the C4 level of the cervical spinal cord; otherwise, an unspecified level code may be more appropriate.
• Distinguish between "initial encounter" (A), "subsequent encounter" (D), and "sequela" (S) based on the patient's treatment phase.
• Always sequence this code after the primary injury code if the central cord syndrome is a direct result of a traumatic event.
