Secondary focal hyperhidrosis
ICD-10 L74.52 is a billable code used to indicate a diagnosis of secondary focal hyperhidrosis.
Secondary focal hyperhidrosis is characterized by excessive sweating localized to specific areas of the body, such as the palms, soles, axillae, or face, which is secondary to an underlying medical condition. This condition can arise from various etiologies, including endocrine disorders (like hyperthyroidism), neurological conditions (such as Parkinson's disease), or certain medications. The clinical presentation typically involves episodes of profuse sweating that can be triggered by heat, stress, or exertion. Anatomically, the sweat glands in the affected areas become overactive, leading to increased perspiration. Disease progression may vary; while some patients experience intermittent episodes, others may have persistent symptoms that significantly impact their quality of life. Diagnostic considerations include a thorough patient history, physical examination, and possibly laboratory tests to identify any underlying conditions contributing to the hyperhidrosis. It is crucial to differentiate secondary focal hyperhidrosis from primary hyperhidrosis, which is idiopathic and not linked to other medical issues.

L74.52 covers cases of secondary focal hyperhidrosis that are linked to conditions such as hyperthyroidism, diabetes, certain cancers, and neurological disorders. It is essential to document the underlying condition to justify the use of this code.
L74.52 should be used when excessive sweating is a symptom of an underlying medical condition. If hyperhidrosis is idiopathic and not linked to any other health issue, L74.51 (primary focal hyperhidrosis) would be more appropriate.
Documentation should include a detailed patient history, identification of the underlying condition, clinical findings, and any diagnostic tests performed. Clear notes on the impact of hyperhidrosis on the patient's daily life can also support the use of this code.
