Burn of 3rd deg mu sites of left wrist and hand, sequela

This code signifies a third-degree burn affecting multiple distinct areas of the left wrist and hand, indicating full-thickness tissue destruction. This type of burn involves damage through all layers of the skin, often extending into subcutaneous tissue, muscle, or bone, and is being addressed as a long-term complication or residual effect of the original injury.

Use this code when documenting the sequelae of a third-degree burn to multiple sites on the left wrist and hand. This applies to encounters for treatment of scarring, contractures, chronic pain, or other lasting complications directly resulting from the initial burn. It should be used after the acute phase of the burn has passed and the patient is being treated for the permanent effects.

• Ensure documentation clearly specifies "third-degree" and "multiple sites" on the left wrist and hand.
• Confirm the encounter is for a sequela (late effect) and not an acute burn injury.
• Always code the specific sequela (e.g., scar, contracture) first, followed by this external cause code.
