Burn of 3rd deg mu sites of right ankle and foot, subs

This code signifies a full-thickness burn affecting multiple areas of the right ankle and foot. A third-degree burn involves destruction of the epidermis and dermis, extending into subcutaneous tissue, and often presents with a dry, leathery appearance and absent sensation.

Apply this code for follow-up care of a patient with a previously diagnosed third-degree burn to multiple sites on their right ankle and foot. This includes subsequent visits for wound care, debridement, skin grafting, or monitoring of healing progress after the initial treatment.

• Ensure documentation specifies "multiple sites" on the right ankle and foot, not just a single area.
• Confirm the encounter is "subsequent" (D) and not initial (A) or sequela (S).
• Always code the extent of the burn (e.g., T31.x) in addition to the specific site code.
