Superficial frostbite of unspecified finger(s), subs encntr

This code signifies a superficial cold-induced injury to an unspecified finger, where tissue damage is limited to the epidermis and possibly the superficial dermis, without blistering or tissue loss. The affected finger(s) are experiencing ongoing care or healing from this frostbite.

Apply this code when a patient presents for follow-up care, such as wound checks, dressing changes, or medication adjustments, for previously diagnosed superficial frostbite of an unspecified finger. It is appropriate for encounters occurring after the initial treatment of the frostbite.

• Ensure documentation specifies "superficial" frostbite and an unspecified finger.
• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Do not use for initial treatment or for sequelae (late effects) of frostbite.
