2025 ICD-10-CM code L74
Eccrine sweat disorders.
Medical necessity for L74 codes relies on demonstrating that the condition significantly impacts the patient's quality of life or is caused by an underlying medical condition that needs to be addressed. For example, excessive sweating can interfere with daily activities and lead to social and emotional distress, while reduced sweating can pose a risk of heatstroke. Documentation should support the severity of symptoms and justify the need for treatment or further investigation.
Diagnosis and treatment of eccrine sweat disorders fall under the purview of dermatologists, primary care physicians, and sometimes other specialists depending on the underlying cause of the disorder.They are responsible for accurate diagnosis, determining the underlying cause if any, and creating a treatment plan to manage symptoms and any related complications.
In simple words: A condition affecting the sweat glands in your skin, causing them to not function correctly.This could mean sweating too much, too little, or other issues related to how your body sweats.
Condition in which there is a deviation from or interruption of the normal structure or function of the sweat glands, which are sweat-producing structures that are embedded in the dermis.
Example 1: A patient presents with excessive sweating of the palms and soles (hyperhidrosis) without an apparent underlying medical condition. This would be coded as L74.512 (Primary Focal Hyperhidrosis, Palms) or L74.513 (Primary Focal Hyperhidrosis, Soles)., A patient experiences heat rash (miliaria), which is a blockage of the sweat ducts. This can manifest as small, clear blisters (miliaria crystallina) and would be coded as L74.1., A patient with diabetes develops abnormal sweating patterns due to autonomic neuropathy (damage to the nerves that control involuntary bodily functions). This is considered a secondary eccrine sweat disorder and could be coded with L74.52 (Secondary focal hyperhidrosis) along with the code for diabetic neuropathy.
Documentation for L74 should include detailed descriptions of the symptoms (location, duration, frequency, severity of sweating, associated symptoms), relevant medical history, family history, results of any diagnostic tests performed, and the physician's clinical assessment.
** For accurate coding, always refer to the most recent version of the ICD-10-CM coding manual and follow official coding guidelines. If you are unsure which code to use, consult with an experienced medical coder or billing specialist.
