Anhidrosis

This code represents the medical condition of anhidrosis, characterized by the inability to sweat normally. This can affect the entire body (generalized anhidrosis) or be localized to specific areas, leading to impaired thermoreoregulation and potential heat-related illnesses.

Use this code when documentation explicitly states a diagnosis of anhidrosis, regardless of its underlying cause. This code is appropriate for both generalized and localized forms of the condition. Supporting documentation should include physician notes detailing the absence or significant reduction of sweating.

• Do not confuse with hyperhidrosis (excessive sweating), which is coded elsewhere.
• Always look for and code any underlying conditions causing the anhidrosis, such as neuropathy or skin disorders, as primary diagnoses if applicable.
• Ensure the documentation clearly distinguishes anhidrosis from hypohidrosis (reduced sweating), as this code specifically refers to the complete absence of sweating.
