Burn third degree of unsp single finger except thumb, subs

This code signifies a full-thickness burn affecting an unspecified single finger, excluding the thumb, where the injury has progressed beyond the initial active treatment phase. The burn has destroyed the epidermis and dermis, potentially extending into subcutaneous tissue, requiring ongoing care such as wound checks, dressing changes, or physical therapy.

Apply this code for follow-up encounters involving a third-degree burn to a single finger (not the thumb) after the initial treatment has been rendered. This includes visits for wound management, infection monitoring, debridement of necrotic tissue, or preparation for skin grafting during the healing process. It is appropriate for any encounter where the patient is receiving active treatment for the burn's sequelae.

• Ensure the documentation specifies a third-degree burn and identifies a single finger other than the thumb.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for initial treatment of the burn; instead, use the "A" seventh character for the initial encounter.
