Heatstroke and sunstroke, sequela

This code signifies the long-term or residual effects resulting from a past episode of heatstroke or sunstroke. These sequelae can manifest as persistent organ damage, neurological deficits, or other chronic health issues directly attributable to the severe heat-related illness.

Use this code when documenting conditions that are a direct consequence of a resolved heatstroke or sunstroke event, occurring after the acute phase has passed. This applies to patients presenting with ongoing symptoms or complications clearly linked to the prior heat-related injury.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., chronic kidney disease, neurological impairment).
• Ensure documentation clearly establishes a causal link between the current condition and the past heatstroke/sunstroke.
• This "S" seventh character indicates sequela, meaning the patient is no longer experiencing the acute effects of the heatstroke.
