Heat exhaustion, unspecified

This code represents a general form of heat exhaustion, a heat-related illness characterized by symptoms such as heavy sweating, fatigue, dizziness, and muscle cramps, resulting from prolonged exposure to heat and inadequate fluid and electrolyte replacement. It indicates a systemic response to heat stress without specific details regarding the type of heat exhaustion.

Use this code when the medical record documents heat exhaustion but does not specify whether it is due to salt depletion or volume depletion. This code is appropriate when the provider's documentation simply states "heat exhaustion" without further differentiation. Documentation should support symptoms consistent with heat exhaustion.

• Avoid using this code if the documentation specifies "heat exhaustion due to salt depletion" (276.51) or "heat exhaustion due to volume depletion" (276.52).
• Always review the entire medical record for more specific details regarding the type of heat exhaustion.
• Consider any associated symptoms or complications, such as dehydration, which may require additional coding.
