Exposure to flames in uncontrolled fire in bldg, sequela

This code signifies a long-term health condition or complication resulting from a previous exposure to flames within an uncontrolled fire inside a building or structure. It indicates that the initial injury has healed, but its lasting effects are still present and require ongoing medical attention.

Apply this code when documenting conditions such as chronic respiratory issues (e.g., asthma, COPD exacerbation) or persistent scarring that are directly attributable to a past fire exposure in a building. This code is appropriate for follow-up encounters addressing these residual effects, not the initial acute injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., T95.0- for sequela of burn).
• Ensure documentation clearly links the current condition to the past fire exposure in a building.
• This "S" seventh character indicates sequela and should only be used for complications or conditions arising after the acute phase of the injury has passed.
