Corrosion of third degree of chest wall, initial encounter

This code signifies a full-thickness chemical burn affecting the chest wall, extending through all layers of skin and potentially into subcutaneous tissue, muscle, or bone. The injury is severe, characterized by a leathery, charred, or waxy appearance, and often results in nerve damage, leading to a painless presentation.

Apply this code for patients presenting with a third-degree chemical burn to the chest wall during their initial treatment for the injury. This includes emergency department visits, initial hospital admissions, or the first encounter with a healthcare provider for this specific corrosion.

• Ensure documentation specifies "third degree" and "corrosion" (chemical burn) to the chest wall.
• Confirm this is the initial encounter for the burn; subsequent care will require a different encounter character.
• Code any associated complications, such as infection or respiratory compromise, separately.
