Burn of second degree of left knee, initial encounter

This code signifies a partial-thickness burn affecting the left knee. It involves damage to the epidermis and dermis, typically presenting with blistering, significant pain, and redness, but without full destruction of the skin layers.

Apply this code for a patient presenting with a newly diagnosed second-degree burn to the left knee, during the period when active treatment for the burn is being provided. This includes initial evaluation, debridement, dressing changes, and pain management.

• Ensure the documentation clearly specifies "second degree" and "left knee" to support this code.
• The "A" seventh character indicates an initial encounter for active treatment; use subsequent characters for later encounters.
• Do not use this code for superficial (first-degree) or full-thickness (third-degree) burns, or for burns to other body sites.
