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

This code signifies a third-degree burn affecting multiple sites on the left shoulder and upper limb, excluding the wrist and hand. A third-degree burn involves full-thickness tissue destruction, extending through all layers of the skin. The "D" suffix indicates that this is a subsequent encounter for the burn, meaning the patient is receiving active treatment for the injury after the initial encounter.

Use this code for follow-up visits where a patient is receiving ongoing care for a severe, full-thickness burn on their left shoulder and upper arm. This includes scenarios like wound care, debridement, or preparation for skin grafting during the acute phase of treatment following the initial injury.

• Ensure the documentation specifies "multiple sites" within the left shoulder and upper limb, and explicitly excludes the wrist and hand.
• Confirm the burn is indeed third-degree; look for terms like "full-thickness" or descriptions of charring/eschar.
• The "D" suffix is crucial for subsequent encounters; do not use for the initial treatment or for sequelae/healing burns.
