Superficial frostbite of right toe(s), subsequent encounter

This code signifies a superficial cold-induced injury to the right foot's digits, specifically frostbite, that is being treated during a follow-up visit. Superficial frostbite involves damage to the skin and subcutaneous tissue, but not deeper structures. The "subsequent encounter" indicates ongoing care for the initial injury.

Apply this code when a patient presents for a follow-up appointment related to previously diagnosed superficial frostbite of the right toes. This includes visits for wound care, monitoring healing progress, or assessing complications arising from the initial frostbite. It is appropriate for any encounter after the initial treatment of the injury.

• Ensure documentation clearly specifies "superficial" frostbite and the "right toe(s)."
• The "D" seventh character is crucial for subsequent encounters; do not use "A" for initial treatment or "S" for sequela.
• Verify laterality (right) is explicitly stated in the medical record.
