Burn of third degree of unspecified toe(s) (nail), sequela

This code signifies a third-degree burn affecting an unspecified toe or toes, including the nail, where the patient is presenting for treatment of the long-term effects or complications of the original burn injury. A third-degree burn involves full-thickness destruction of the skin and underlying tissues. The "sequela" designation indicates that the acute burn has healed, and the current encounter addresses residual problems such as scarring, contractures, chronic pain, or functional impairment.

Use this code when documenting follow-up care for a patient who previously sustained a third-degree burn to an unspecified toe(s) and is now being treated for a chronic condition or complication directly resulting from that burn. Examples include surgical revision of burn scars on the toe, physical therapy for toe contractures, or management of chronic neuropathic pain in the affected digit. This code is appropriate for encounters occurring long after the initial burn event has resolved.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the original burn injury, even for sequela codes.
• Do not use this code for acute burn treatment; use the appropriate acute burn code (T25.33-) with an A, D, or G seventh character.
• Ensure documentation clearly links the current condition to the previous third-degree toe burn and specifies the "sequela" nature of the encounter.
