Injury of median nerve at upper arm level, left arm, subs

This code signifies a documented injury to the median nerve located in the upper arm of the patient's left limb. This injury is being addressed during a subsequent encounter, meaning the patient is receiving follow-up care for a previously diagnosed and treated median nerve injury.

Apply this code when a patient presents for ongoing management, follow-up, or rehabilitation of a left upper arm median nerve injury. This includes scenarios such as physical therapy sessions, re-evaluation of nerve function, or wound care after initial treatment. It is appropriate for any encounter after the initial treatment phase.

• Ensure documentation clearly specifies the left arm and the upper arm level of the median nerve injury.
• Verify the encounter type is "subsequent" (D) and not initial (A) or sequela (S).
• Confirm the injury is to the median nerve, not another nerve in the same anatomical region.
