Exertional heatstroke, sequela

This code signifies the long-term or residual effects resulting from a past episode of exertional heatstroke. These sequelae can manifest as persistent neurological deficits, organ damage, or other chronic conditions that developed as a direct consequence of the initial heatstroke event. The acute phase of the heatstroke has resolved, but its lasting impact remains.

Use this code when documenting and billing for the treatment or management of a patient's chronic health problems that are directly attributable to a previous exertional heatstroke. This applies to follow-up visits, rehabilitation services, or ongoing care for conditions like cognitive impairment, kidney dysfunction, or muscle weakness that originated from the heatstroke. It should be used after the acute phase of the heatstroke has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., G93.1 for anoxic brain damage).
• Ensure documentation clearly links the current condition to a past exertional heatstroke event.
• The "S" in the 7th character indicates sequela, meaning it's for conditions that are the late effects of the initial injury.
