Injury of nerves at wrist and hand level of unsp arm, subs

This code signifies damage to any nerve in the wrist or hand, excluding the median, ulnar, or radial nerves, in an unspecified arm. The injury is not a new occurrence but rather a follow-up or healing phase of a previously sustained trauma.

Apply this code for subsequent encounters when a patient presents for ongoing treatment, evaluation, or management of an injury to a less common nerve (e.g., dorsal cutaneous branch of the ulnar nerve, palmar cutaneous branch of the median nerve) in the wrist or hand. This includes situations like wound care, physical therapy, or monitoring nerve regeneration after the initial injury.

• Ensure documentation clearly indicates a "subsequent encounter" for the injury.
• Confirm that the specific nerve injured is not the median, ulnar, or radial nerve.
• Verify that the affected arm is not specified in the medical record.
