Superficial frostbite of right wrist, subsequent encounter

This code signifies a superficial cold-induced injury to the right wrist, specifically frostbite affecting only the skin and subcutaneous tissue, without deeper tissue involvement. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed condition, such as wound care, monitoring, or evaluation of healing.

Apply this code when documenting follow-up visits for a patient with superficial frostbite of the right wrist. This includes scenarios where the patient is returning for dressing changes, re-evaluation of the affected area, or assessment of recovery after initial treatment. It is appropriate for any encounter after the initial diagnosis and treatment of the frostbite.

• Ensure documentation clearly specifies "superficial" frostbite and the "right wrist."
• Verify the encounter type is subsequent, not initial, for appropriate code selection.
• Distinguish from deeper frostbite (T34.-) or other cold-related injuries.
