Frostbite with tissue necrosis of right wrist, subs encntr

This diagnosis code indicates a severe cold-related injury to the right wrist where the tissue has died due to freezing. It signifies that the patient is receiving follow-up care for this specific frostbite injury, which has progressed beyond initial presentation to tissue necrosis.

Apply this code when documenting subsequent encounters for a patient whose right wrist previously sustained frostbite, and that injury has resulted in tissue death. This is appropriate for ongoing management, wound care, or evaluation of complications related to the necrotic tissue.

• Ensure documentation clearly specifies "right wrist" and "tissue necrosis" to support this code.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use for initial treatment of the frostbite or for sequelae (late effects) once the acute phase has passed.
