Burn of first degree of right thumb (nail), init encntr

This code signifies a superficial burn affecting only the outermost layer of skin (epidermis) on the right thumb, including the nail region. It is characterized by redness, mild swelling, and pain, without blistering or skin breakage.

Apply this code for initial treatment of a first-degree burn to the right thumb, such as from brief contact with a hot surface (e.g., hot plate, steam). This is appropriate when the patient presents for the first time for this specific injury.

• Ensure the documentation specifies "first degree" and clearly identifies the "right thumb" as the affected area.
• Verify the encounter is "initial" for this burn; subsequent encounters would use a different seventh character.
• Distinguish from second- or third-degree burns, which involve deeper tissue damage and have different codes.
