Burn of second degree of chest wall, subsequent encounter

This code signifies a partial-thickness burn affecting the chest wall, characterized by blistering, pain, and redness, that is being treated during a follow-up visit after the initial encounter. The burn involves the epidermis and part of the dermis, but not the full thickness of the skin.

Apply this code when a patient presents for ongoing management, wound care, or evaluation of a previously diagnosed second-degree burn to the chest wall. This would include situations like dressing changes, re-evaluation of healing progress, or assessment for complications during the healing phase.

• Ensure the documentation clearly indicates a "subsequent encounter" for the burn.
• Verify the burn degree is specifically documented as second-degree.
• Confirm the anatomical site is precisely the "chest wall."
