Primary focal hyperhidrosis, soles

This code signifies a chronic condition characterized by excessive, localized sweating on the soles of the feet, without an underlying medical cause. It is a primary (idiopathic) form of hyperhidrosis, meaning it is not secondary to another disease or medication.

Apply this code when documentation clearly indicates primary hyperhidrosis specifically affecting the soles of the feet. This diagnosis is typically made after ruling out secondary causes of hyperhidrosis through patient history and physical examination.

• Ensure documentation specifies "primary" or "idiopathic" hyperhidrosis to differentiate from secondary forms.
• Verify the anatomical site is explicitly stated as "soles" or "plantar" to support this specific code.
• Do not confuse with generalized hyperhidrosis or hyperhidrosis affecting other body sites.
