Corrosion of second degree of buttock, subsequent encounter

This code signifies a second-degree burn, specifically caused by corrosive chemicals, affecting the buttock region. A second-degree burn involves damage to the epidermis and dermis, characterized by blistering, pain, and redness. The "subsequent encounter" indicates that this code is used for follow-up care after the initial treatment of the injury.

Use this code for ongoing management, wound care, or evaluation of a chemical burn to the buttock that was initially treated in a previous encounter. This applies to situations where the patient is returning for dressing changes, infection checks, or assessment of healing progress for a second-degree corrosive burn.

• Ensure the documentation clearly specifies a corrosive agent as the cause of the burn.
• Verify the burn degree is explicitly documented as second-degree.
• Confirm this is not the initial encounter for this specific injury; use an initial encounter code for the first visit.
