Heat exhaustion, anhydrotic, sequela

This code signifies the long-term or residual effects stemming from a past episode of anhydrotic heat exhaustion. Anhydrotic heat exhaustion is a severe form of heat-related illness characterized by the body's inability to sweat, leading to overheating. The sequela may include chronic neurological deficits, persistent organ damage, or ongoing functional limitations.

Apply this code when documenting conditions that are a direct consequence of a resolved anhydrotic heat exhaustion event, and these conditions are still present after the acute phase has passed. This is appropriate for follow-up encounters addressing the lasting impact of the previous heat-related illness.

• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., chronic kidney disease due to heat exhaustion).
• Ensure documentation clearly links the current condition to a past episode of anhydrotic heat exhaustion.
• The "S" in the 7th character indicates sequela and should be used for conditions that are the late effects of the initial injury.
