Generalized hyperhidrosis

This code represents a medical condition characterized by excessive, widespread sweating that is not limited to a specific body area. This overactive perspiration occurs without an apparent physiological cause or in response to a generalized underlying medical condition. It significantly impacts a patient's quality of life due to constant dampness and potential skin issues.

Use this code when documentation clearly indicates hyperhidrosis affecting the entire body or large, non-localized areas. This diagnosis is supported by physician notes describing generalized excessive sweating, often detailing its impact on daily activities and ruling out focal causes. It is appropriate when the hyperhidrosis is a primary condition or a generalized manifestation of a systemic disease.

• Ensure documentation specifies "generalized" hyperhidrosis to differentiate from localized forms.
• Review "Excludes1" notes carefully to avoid co-coding with focal or localized hyperhidrosis (L74.5-).
• If an underlying systemic condition is identified as the cause, code that condition first, followed by this code.
