Corrosion of second degree of chest wall, initial encounter

This code signifies a second-degree chemical burn affecting the chest wall. It indicates damage to the epidermis and dermis, characterized by blistering, pain, and redness, resulting from exposure to a corrosive substance. This specific code is used for the initial treatment of such an injury.

Apply this code when documenting the first encounter for a patient presenting with a second-degree chemical burn to the chest. This includes situations where the patient is initially evaluated and treated in an emergency department, urgent care, or physician's office for this specific injury.

• Ensure documentation clearly specifies the chest wall as the affected body part and confirms a second-degree injury.
• Verify that the encounter is indeed the initial treatment for this specific corrosion. Subsequent encounters would require a different seventh character.
• Always code the external cause of the corrosion (e.g., chemical, acid) using an appropriate external cause code in addition to this diagnosis.
