Heat exposure on board sailboat, sequela

This code indicates a long-term health condition or complication resulting from a past incident of heat exposure experienced while on a sailboat. It signifies that the acute heat-related illness has resolved, but its lingering effects are now being treated or evaluated.

Apply this code when documenting conditions such as chronic fatigue, persistent neurological deficits, or kidney damage that are directly attributed to a previous episode of heatstroke or heat exhaustion sustained on a sailboat. This code is appropriate for follow-up encounters addressing these sequelae, not the initial acute event.

• Requires a seventh character "S" to indicate sequela.
• Always sequence this code after the code for the specific sequela being treated (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a past heat exposure event on a sailboat.
