ICD-10 Code L74.513 – Primary focal hyperhidrosis, soles (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L74.513 – Primary focal hyperhidrosis, soles
What it is
L74.513 identifies primary focal hyperhidrosis limited to the soles. It means excessive sweating of the feet without an underlying systemic cause.
Clinical signs
Patients typically report persistent, excessive plantar sweating that interferes with daily activities. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents primary focal hyperhidrosis affecting the soles only. It fits cases described as idiopathic or localized sweating of the feet. Check documentation if the record also suggests a secondary cause, generalized sweating, or involvement of other sites.
Do not use for
Do not use L74.513 for generalized hyperhidrosis or sweating caused by another condition. Do not use it when the feet are mentioned only as part of a broader disorder. Check documentation.
Coding tip
Confirm that the provider specifies primary focal hyperhidrosis and the soles, not just “excess sweating” or “foot sweating.”
