Generalized hyperhidrosis

This code represents a medical condition characterized by excessive, widespread sweating that is not localized to a specific body area. It indicates a systemic overproduction of sweat, often without an identifiable underlying cause (idiopathic) or as a manifestation of another systemic condition.

Use this code when documentation clearly indicates generalized, non-focal hyperhidrosis affecting the entire body or large, diffuse areas. This diagnosis is supported by physician notes describing excessive sweating that is not attributable to environmental factors or localized conditions.

• Differentiate from focal hyperhidrosis (e.g., palmar, plantar, axillary), which would be coded differently.
• Always look for an underlying secondary cause; if identified, code the underlying condition first, followed by this code.
• Ensure the documentation specifies "generalized" or "diffuse" to support the use of this code.
