Heat exhaustion, unspecified, sequela

This code signifies the long-term or residual effects resulting from a past episode of unspecified heat exhaustion. These sequelae can manifest as chronic fatigue, persistent weakness, or other enduring symptoms that are directly attributable to the prior heat-related illness. It indicates that the acute phase of heat exhaustion has resolved, but its impact continues to affect the patient's health.

Apply this code when documenting conditions that are a direct consequence of a previously experienced, but not otherwise specified, heat exhaustion event. This is appropriate for follow-up encounters where the patient presents with ongoing health issues clearly linked to the past heat exposure, rather than an acute or current episode.

• Always sequence this sequela code after the code for the specific residual condition(s) being treated.
• Ensure documentation clearly establishes the causal link between the current symptoms and the prior heat exhaustion.
• Avoid using this code for acute or current heat exhaustion; instead, use the appropriate acute heat exhaustion codes.
