Exhaustion due to exposure, sequela

This code signifies the long-term or residual effects stemming from a previous episode of exhaustion caused by environmental exposure. It indicates that the acute phase of exhaustion has passed, but the patient continues to experience lasting symptoms or complications directly attributable to that past event.

Apply this code when documenting conditions like chronic fatigue, persistent weakness, or other enduring health issues that are a direct consequence of a prior, resolved episode of exhaustion due to factors such as extreme heat, cold, or overexertion. This is appropriate when the initial acute exhaustion is no longer present, but its sequelae are being treated.

• Always sequence this code after the code for the specific sequela being treated (e.g., chronic fatigue, muscle weakness).
• Ensure documentation clearly links the current condition to a past episode of exhaustion due to exposure.
• This code is for the sequela of exhaustion, not the acute exhaustion itself.
