Anhidrosis

This code represents the medical condition of anhidrosis, characterized by the inability to sweat normally. This can affect a small area or the entire body, leading to impaired thermoregulation and potential heat-related illnesses.

Use this code when documentation clearly indicates a diagnosis of anhidrosis, regardless of its underlying cause. This code is appropriate for patients presenting with symptoms such as heat intolerance, dizziness, or absent/reduced sweating, confirmed by clinical examination or sweat tests.

• Always seek documentation specifying the underlying cause of anhidrosis if known, as a more specific code may be available (e.g., neurological disorders, skin conditions).
• Do not confuse this with hyperhidrosis (excessive sweating); these are distinct conditions.
• Consider sequencing this code as a secondary diagnosis if the anhidrosis is a symptom of a primary underlying condition.
