Heat syncope, sequela

This code signifies the long-term or residual effects resulting from a past episode of heat syncope. These sequelae are persistent conditions directly attributable to the physiological impact of the original heat-induced fainting spell, rather than the acute event itself.

Apply this code when documenting a patient presenting with chronic or lasting symptoms that are a direct consequence of a previously experienced heat syncope. This includes conditions like persistent orthostatic intolerance, chronic fatigue, or neurological deficits that developed after and are attributed to the heat-related fainting. It should be used in conjunction with a code for the specific sequela being treated.

• Always sequence this code after the code describing the specific sequela (e.g., chronic orthostatic hypotension).
• Ensure documentation clearly links the current condition to a past episode of heat syncope.
• Do not use this code for the acute episode of heat syncope; use the acute heat syncope code (T67.1XXA) for that.
