Injury of unsp nerve at wrs/hnd lv of right arm, sequela

This code signifies a lasting effect or complication resulting from an unspecified nerve injury located in the wrist or hand region of the patient's right arm. The original injury has resolved, but the patient continues to experience symptoms or deficits directly attributable to the nerve damage.

Apply this code when documentation clearly indicates a sequela (e.g., chronic pain, numbness, weakness, or functional impairment) stemming from a past, unspecified nerve injury to the right wrist or hand. This is appropriate when the acute phase of the injury has passed, and the patient is being treated for the long-term consequences.

• Ensure documentation explicitly states "sequela" or describes a chronic condition resulting from a previous injury.
• Confirm the injury site is the right wrist or hand, and the affected structure is a nerve, even if the specific nerve is not identified.
• Always sequence this sequela code after the primary diagnosis for the current encounter, if applicable, or as the primary diagnosis if the sequela is the reason for the encounter.
