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

This code signifies a full-thickness burn affecting multiple areas of the right shoulder and upper arm, excluding the wrist and hand. The injury has progressed beyond the initial treatment phase, and the patient is receiving active treatment for complications, healing, or sequelae.

Apply this code when a patient presents for follow-up care of a third-degree burn to the right shoulder and upper limb (excluding wrist/hand), such as wound care, debridement, skin grafting, or management of infection. It is appropriate for any encounter after the initial treatment of the acute injury.

• Ensure the burn is explicitly documented as third-degree and involves multiple sites within the specified anatomical region.
• Confirm the encounter is for subsequent care, not the initial treatment of the burn.
• Always code additional external cause codes (e.g., X00-X99) to describe the circumstances of the burn.
