Heat exposure on board fishing boat, sequela

This code signifies a long-term health condition or complication arising from a past incident of heat exposure experienced while on a fishing boat. It indicates that the patient is currently presenting with a health issue directly attributable to that historical event, rather than an acute heat-related illness.

Apply this code when documenting a patient's current medical problem that is a direct consequence of a previous heat exposure incident that occurred on a fishing vessel. This is appropriate for conditions like chronic kidney disease exacerbated by prior severe dehydration from heatstroke at sea, or persistent neurological deficits following a past heat injury sustained while fishing.

• Always use a secondary code to identify the specific sequela (e.g., chronic kidney disease, neurological disorder).
• Ensure documentation clearly links the current condition to the past heat exposure on the fishing boat.
• Do not use for acute heat-related illnesses; this code is exclusively for residual effects.
