Superficial frostbite of right hand, subsequent encounter

This code signifies a superficial frostbite injury to the patient's right hand that is currently undergoing active treatment or follow-up care. Superficial frostbite involves damage to the outer layers of the skin, often presenting with numbness, tingling, and a waxy appearance, without deep tissue involvement.

Use this code for any encounter after the initial treatment of superficial frostbite to the right hand, such as follow-up appointments, wound care, or medication adjustments. It is appropriate when the patient is still receiving care for the acute effects of the frostbite.

• Ensure documentation specifies "superficial" frostbite and the "right hand" to support this code.
• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use for initial treatment (use "A" for initial encounter) or for sequelae/late effects (use "S" for sequela).
