In simple words: This code describes excessive sweating only on the soles of the feet, not due to another medical condition.

L74.513, Primary focal hyperhidrosis, soles, is an ICD-10-CM code that specifies primary focal hyperhidrosis localized to the soles of the feet.This indicates excessive sweating in this specific area, originating from a primary cause rather than a secondary condition.It is distinct from generalized hyperhidrosis affecting the entire body.

Example 1: A patient presents with complaints of excessive sweating limited to the soles of their feet, impacting their daily activities.After a physical examination and excluding other causes, the physician diagnoses primary focal hyperhidrosis, soles (L74.513)., A patient with a history of plantar hyperhidrosis undergoes iontophoresis treatment.The physician documents the diagnosis of primary focal hyperhidrosis of the soles and records code L74.513 for billing and medical record accuracy., A patient visits a podiatrist reporting excessive foot sweating that interferes with wearing certain types of shoes and performing their job.The podiatrist confirms primary focal hyperhidrosis of the soles through a physical exam and uses L74.513 for the diagnosis.

Thorough documentation should include the patient's history of excessive sweating in the soles of the feet, the duration of the condition, any triggers, and the impact it has on the patient's daily life.Physical examination findings should also be recorded, along with any differential diagnoses considered and why they were excluded.The physician should specify that the hyperhidrosis is primary (not due to another condition).

** This code should only be used for primary focal hyperhidrosis; if the excessive sweating is secondary to another medical condition, a different code should be used.Consider using additional codes to document the severity of hyperhidrosis or any comorbidities.
