Primary focal hyperhidrosis, axilla
ICD-10 L74.510 is a billable code used to indicate a diagnosis of primary focal hyperhidrosis, axilla.
Primary focal hyperhidrosis of the axilla is a condition characterized by excessive sweating localized to the underarm area, which can significantly impact the quality of life for affected individuals. The condition typically presents in adolescence or early adulthood and is thought to be due to overactivity of the sympathetic nervous system. Patients may experience episodes of sweating that are disproportionate to the heat or exertion, often leading to social embarrassment and anxiety. The axillary region is anatomically rich in sweat glands, and the hyperhidrosis can lead to skin irritation, maceration, and secondary infections if left untreated. Disease progression can vary; while some patients may experience persistent symptoms, others may find that the severity diminishes over time. Diagnosis is primarily clinical, based on patient history and physical examination, with the use of diagnostic tests such as the starch-iodine test to confirm excessive sweating. Treatment options include topical antiperspirants, iontophoresis, botulinum toxin injections, and in severe cases, surgical intervention. Accurate diagnosis and management are crucial to alleviate symptoms and improve patients' quality of life.

L74.510 specifically covers primary focal hyperhidrosis localized to the axillary region. It does not include secondary causes of hyperhidrosis, which may be due to underlying medical conditions or medications.
L74.510 should be used when the patient presents with excessive sweating specifically in the axillary area without any identifiable secondary cause. If hyperhidrosis is generalized or due to another condition, other codes should be considered.
Documentation should include a detailed patient history, physical examination findings, and any diagnostic tests performed. Evidence of the impact of hyperhidrosis on the patient's daily life and any previous treatments attempted should also be included.
