Burn 3rd deg mu sites of left lower limb, ex ank/ft, init

This diagnosis code signifies a severe, full-thickness burn affecting multiple areas of the left leg, excluding the ankle and foot. These burns involve damage to all layers of the skin, often extending into underlying tissues, and typically present with a leathery, charred, or waxy appearance.

Apply this code for initial encounters involving patients presenting with third-degree burns across various sites of their left thigh, knee, or calf. This is appropriate when the burn injury is acute and the patient is receiving active treatment for the burn itself.

• Ensure documentation specifies "third degree" and "multiple sites" within the left lower limb (excluding ankle/foot).
• Verify this is the initial encounter for this specific burn injury. Subsequent care would use a different encounter character.
• Always code the extent of the burn (e.g., total body surface area affected) with an additional code if documented.
