Corrosion of third degree of buttock, sequela

This code signifies a third-degree burn, specifically a corrosion, affecting the buttock region, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication directly resulting from that past injury. Third-degree burns involve full-thickness skin destruction, often extending into subcutaneous tissue. The "corrosion" aspect indicates the burn was caused by a chemical agent.

Use this code when documenting the long-term effects or complications of a previously sustained third-degree chemical burn to the buttock. This includes scenarios such as scar contractures, chronic pain, non-healing ulcers, or functional limitations directly attributable to the original injury. This code is appropriate when the initial burn has resolved and the focus of care is on the sequela.

• Always ensure documentation clearly links the current condition to the past third-degree chemical burn of the buttock.
• Do not use this code for the initial or acute treatment of the burn; it is exclusively for sequelae.
• Consider additional codes for specific sequelae, such as scar contracture (e.g., L90.5) or chronic pain (e.g., G89.29), to provide a comprehensive clinical picture.
