Corros 3rd deg mu sites of shldr/up lmb, ex wrs/hnd, subs

This code signifies a severe, full-thickness burn injury affecting multiple areas of the shoulder and/or upper arm, but not the wrist or hand. The damage extends through all layers of skin, often involving underlying tissue, and is documented during a follow-up visit for ongoing care.

Apply this code when a patient presents for subsequent treatment of a third-degree corrosion (chemical burn) that impacted various sites on the shoulder and/or upper limb (excluding the wrist and hand). This would include scenarios like wound care, debridement, or skin grafting procedures performed after the initial encounter.

• Ensure documentation clearly specifies "third degree" and "multiple sites" within the shoulder/upper limb region (excluding wrist/hand).
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Verify the burn is explicitly described as a "corrosion" (chemical burn) rather than a thermal burn.
