Oth exposure to uncontrolled fire, not in bldg, subs

This code signifies an injury or condition resulting from a patient's exposure to an uncontrolled fire that occurred outdoors, not within a building or defined structure, and is being treated after the initial encounter. This could include fires in open fields, forests, or outdoor debris piles. The "subsequent encounter" indicates ongoing care for the effects of this exposure.

Apply this code when documenting follow-up care for burns, smoke inhalation, or other injuries sustained from an outdoor, uncontrolled fire. This is appropriate for patients returning for wound care, physical therapy, or monitoring of respiratory complications related to the initial incident. It should be used after the initial acute treatment has been rendered.

• Ensure the documentation clearly states the fire occurred outdoors and not within a building.
• Verify that the encounter is for follow-up care, not the initial treatment of the injury.
• Always code the specific injury (e.g., burn, smoke inhalation) first, followed by this external cause code.
