Heat exhaustion due to salt depletion

This code signifies a form of heat exhaustion primarily caused by inadequate sodium intake or excessive sodium loss, leading to symptoms such as fatigue, nausea, headache, and muscle cramps. It represents a milder heat-related illness compared to heatstroke, characterized by the absence of central nervous system dysfunction or significantly elevated core body temperature.

Assign this code when documentation clearly indicates heat exhaustion where the primary contributing factor is identified as salt depletion, often seen in individuals performing strenuous activity in hot environments without adequate electrolyte replacement. Supporting documentation should detail symptoms consistent with heat exhaustion and explicitly mention salt or sodium depletion as the cause.

• Differentiate from other forms of heat exhaustion (e.g., due to anhidrosis) and heatstroke, which involve more severe systemic effects.
• Ensure the medical record specifies "salt depletion" or "sodium depletion" as the etiology; otherwise, a more general heat exhaustion code may be appropriate.
• Consider any associated dehydration or electrolyte imbalances, but prioritize the salt depletion as the primary cause for this specific code.
