Heat exhaustion due to salt depletion, subsequent encounter

This code signifies a patient presenting with symptoms of heat exhaustion primarily caused by inadequate salt intake, rather than just water loss, during a follow-up visit or subsequent phase of care. It indicates a less severe form of heat-related illness compared to heat stroke, characterized by symptoms like muscle cramps, fatigue, dizziness, and nausea.

Use this code when a patient is seen for ongoing management, evaluation of recovery, or complications related to a previously diagnosed episode of salt depletion heat exhaustion. This applies to scenarios such as a follow-up appointment after initial treatment in an emergency department, or a return visit to a primary care physician for persistent symptoms.

• Ensure documentation clearly specifies "salt depletion" as the primary cause of heat exhaustion, distinguishing it from other forms.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving care after the initial treatment of the condition.
• Do not use this code for the initial diagnosis and treatment of heat exhaustion due to salt depletion; refer to the appropriate "A" (initial encounter) code.
