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

This code signifies a full-thickness burn affecting the right thumb, including the nailbed, where all layers of skin are destroyed. The injury presents with charring, eschar formation, and often a waxy or leathery appearance, with nerve endings destroyed resulting in a lack of sensation.

Apply this code for the initial treatment of a patient presenting with a third-degree burn specifically located on their right thumb. This includes emergency department visits, initial hospital admissions, or the first encounter with a healthcare provider for this specific burn injury.

• Confirm the burn depth is documented as "third degree" or "full thickness."
• Verify the anatomical site is explicitly the "right thumb" and not another digit or part of the hand.
• Ensure this is the patient's first encounter for this specific burn to use the "A" seventh character.
