Focal hyperhidrosis
ICD-10 L74.5 is a used to indicate a diagnosis of focal hyperhidrosis.
Focal hyperhidrosis is a condition characterized by excessive sweating localized to specific areas of the body, such as the palms, soles, axillae, or face. This condition is often idiopathic, meaning the exact cause is unknown, but it may be linked to genetic factors, hormonal changes, or autonomic nervous system dysfunction. Clinically, patients present with episodes of excessive sweating that can occur spontaneously or be triggered by stress, heat, or physical activity. The anatomy involved includes eccrine sweat glands, which are densely concentrated in the affected areas. Disease progression can vary; while some individuals may experience symptoms throughout their lives, others may find that symptoms diminish with age. Diagnostic considerations include a thorough patient history, physical examination, and potentially the use of quantitative sudomotor axon reflex test (QSART) to measure sweat production. It is essential to differentiate focal hyperhidrosis from secondary causes of hyperhidrosis, such as endocrine disorders or infections, to ensure appropriate management.

L74.5 specifically covers focal hyperhidrosis, which includes excessive sweating localized to areas such as the palms, soles, axillae, and face. It does not cover generalized hyperhidrosis or secondary hyperhidrosis due to underlying medical conditions.
L74.5 should be used when the sweating is localized and not due to a systemic condition. If the hyperhidrosis is generalized or secondary to another medical issue, other codes should be considered.
Documentation should include a detailed patient history, physical examination findings, and any diagnostic tests performed, such as QSART. Treatment plans and responses to therapy should also be documented to support the diagnosis.
