Contact with hot engines, machinery and tools, sequela

This code signifies the long-term effects or complications arising from an injury caused by contact with hot engines, machinery, or tools. It is used when the acute injury has healed, but residual problems, such as scarring, chronic pain, or functional limitations, persist.

Apply this code when documenting a patient presenting for treatment of a condition that is a direct consequence of a past burn or thermal injury from hot industrial equipment. This would include follow-up visits for scar revision due to a previous engine burn, or management of nerve damage resulting from contact with a hot tool.

• Always sequence this code after the code(s) describing the specific sequela (e.g., scar, chronic pain).
• Ensure documentation clearly links the current condition to the original injury from hot engines, machinery, or tools.
• Do not use this code for the initial acute injury; instead, use the appropriate acute burn code.
