Exposure to flames in uncontrolled fire, not in bldg, subs

This code signifies a patient's follow-up visit for injuries or complications resulting from direct contact with flames in an outdoor, non-structural fire. This includes fires occurring in open fields, forests, or other outdoor environments not enclosed by a building.

Apply this code for subsequent encounters when a patient presents for ongoing treatment, wound care, or evaluation of sequelae related to burns or other injuries sustained from an uncontrolled outdoor flame exposure. Examples include follow-up for burn wound infections, scar management, or physical therapy after the initial injury.

• Ensure the encounter is for follow-up care, not the initial injury.
• Confirm the fire occurred outdoors and not within a building or structure.
• Always code the specific burn injury (e.g., T20-T25) as the primary diagnosis, with this code as an external cause.
