Primary focal hyperhidrosis, soles
ICD-10 L74.513 is a billable code used to indicate a diagnosis of primary focal hyperhidrosis, soles.
Primary focal hyperhidrosis of the soles is a condition characterized by excessive sweating localized to the feet, which can significantly impact a patient's quality of life. This condition typically presents in adolescence or early adulthood and is often bilateral, affecting both feet symmetrically. The excessive sweating is not secondary to any underlying medical condition and is thought to be due to overactivity of the sympathetic nervous system. The anatomy involved includes the eccrine sweat glands located in the skin of the soles, which are responsible for thermoregulation. Disease progression can vary; while some individuals may experience mild symptoms, others may have severe sweating that leads to social anxiety, skin irritation, and fungal infections. Diagnostic considerations include a thorough patient history, physical examination, and potentially the use of the starch-iodine test to confirm hyperhidrosis. It is essential to differentiate primary hyperhidrosis from secondary causes, such as endocrine disorders or medication side effects, to ensure appropriate management.

L74.513 specifically covers primary focal hyperhidrosis affecting the soles of the feet, characterized by excessive sweating without an identifiable secondary cause.
L74.513 should be used when the sweating is localized to the soles and is not due to any underlying medical condition, differentiating it from generalized hyperhidrosis or secondary causes.
Documentation should include a detailed patient history, physical examination findings, and any diagnostic tests performed, such as the starch-iodine test, to confirm the diagnosis of primary focal hyperhidrosis.
