Superficial frostbite of right knee and lower leg, subs

This code signifies a superficial cold-induced injury, specifically frostbite, affecting the right knee and/or the lower leg. It indicates that the patient is receiving follow-up care for this condition after the initial treatment phase.

Apply this code when a patient presents for ongoing management, wound care, or evaluation of complications related to a superficial frostbite injury of the right knee and lower leg. This includes visits for dressing changes, monitoring healing, or addressing persistent symptoms after the initial encounter.

• Ensure documentation specifies "superficial" frostbite and the right lower extremity (knee and/or lower leg).
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Do not use for initial treatment of the frostbite; a different seventh character would be appropriate for the initial encounter.
