Burn of second degree of left knee, subsequent encounter

This code signifies a partial-thickness burn affecting the left knee, characterized by blistering, pain, and redness, that is being treated after the initial encounter for the injury. The burn involves the epidermis and part of the dermis, but not the full thickness of the skin.

Apply this code when a patient presents for follow-up care, wound checks, dressing changes, or further management of a second-degree burn on their left knee after the initial treatment has already been provided. This includes situations where the burn is healing but still requires ongoing medical attention.

• Ensure the documentation clearly specifies "left knee" and "second degree" for accurate assignment.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Do not use for initial treatment of the burn or for sequelae (late effects) of the burn.
