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

This code signifies a full-thickness burn affecting the right thumb, including the nailbed, where the injury has progressed beyond the initial treatment phase. This type of burn involves destruction of all skin layers, often extending into subcutaneous tissue, bone, or muscle, and typically presents with a leathery, waxy, or charred appearance.

Apply this code when documenting a patient's visit for ongoing care, follow-up, or complications related to a third-degree burn of the right thumb after the initial encounter for the injury. This includes scenarios such as wound care, debridement, skin grafting procedures, or management of infection during the healing process.

• Ensure the documentation clearly specifies "subsequent encounter" for the burn.
• Verify the burn is indeed third-degree and specifically involves the right thumb.
• Do not use for initial treatment of the burn; a code with an "A" seventh character would be appropriate for the initial encounter.
