Medical necessity is established by the presence of significant symptoms impacting the patient's quality of life or posing health risks (e.g., heat intolerance in hypohidrosis).
A dermatologist or primary care physician is typically responsible for diagnosing and managing eccrine sweat disorders.The clinical responsibility involves a thorough history taking, physical examination, and possibly further investigations to identify the underlying cause and implement appropriate treatment.

L74.9, Eccrine sweat disorder, unspecified, is an ICD-10-CM code that classifies a non-specific disorder affecting the eccrine sweat glands.Eccrine glands are the most common type of sweat gland in humans, responsible for thermoregulation. Disorders can manifest as hypohidrosis (reduced sweating), hyperhidrosis (excessive sweating), or other variations in sweat production or function.This code is used when a more specific type of eccrine sweat disorder cannot be identified.It is crucial to document the specific symptoms and findings to support the use of this code.
Example 1: A patient presents with generalized decreased sweating, making them susceptible to overheating.No specific cause for the hypohidrosis can be found after evaluation., A patient experiences excessive sweating of the hands, but the cause is unclear despite a thorough investigation., A patient presents with a combination of symptoms related to sweat gland dysfunction but further testing is needed to pinpoint the specific disorder.
Detailed patient history including onset, duration, and character of sweating abnormalities; physical examination findings; results of any diagnostic tests performed (e.g., sweat test, biopsy); and treatment plan.
** This code is often used as a placeholder when a more precise diagnosis is pending or unavailable. It’s essential to review the clinical documentation carefully to determine if a more specific code is appropriate.
