Exposure to sofa fire due to unsp burning material, subs

This code indicates a patient presenting for follow-up care or complications stemming from an injury sustained during a sofa fire. The specific material that ignited the sofa is not documented or is unknown. This code is used after the initial treatment for the burn or injury has been rendered.

Apply this code when a patient returns for subsequent treatment of burns, smoke inhalation, or other injuries directly resulting from a sofa fire, and the burning material was not identified in the medical record. This includes wound care, physical therapy, or management of long-term complications.

• Requires a 7th character "D" for subsequent encounter.
• Always sequence this external cause code after the primary injury code(s).
• Ensure the medical record clearly indicates the encounter is for follow-up care related to the initial sofa fire injury.
