Exposure to excessive heat of man-made origin, sequela

This code describes the long-term or residual effects resulting from a past exposure to dangerously high temperatures generated by artificial sources. These sequelae can manifest as chronic skin conditions, neurological deficits, or other persistent health problems that developed after the initial acute injury from man-made heat.

Use this code when documenting conditions such as chronic scarring from a severe burn caused by a hot appliance, persistent nerve damage following exposure to industrial heat, or long-term respiratory issues from inhaling superheated steam. It is appropriate for follow-up encounters where the primary injury has resolved but its lasting consequences are being treated.

• Always sequence this sequela code after the code for the specific residual condition being treated.
• Ensure the medical record clearly links the current condition to a past exposure to man-made excessive heat.
• Do not use this code for acute heat-related illnesses or injuries; those require codes from the initial encounter or subsequent encounter categories.
