Acne tropica

This code represents a severe form of acne, characterized by deep inflammatory nodules, abscesses, and sinus tracts, primarily affecting individuals in tropical or subtropical climates. It is often exacerbated by heat, humidity, and occlusive clothing, leading to extensive scarring.

Assign this code when documentation explicitly states "acne tropica" or describes a severe, inflammatory acne presentation consistent with this condition, particularly in patients with a history of exposure to tropical environments. Supporting documentation should detail the characteristic lesions and their distribution.

• Differentiate from other severe acne forms like acne conglobata (L70.1) or acne fulminans (L70.2) if the tropical context is not specified.
• Ensure the provider's documentation clearly links the acne to tropical factors or uses the specific term "acne tropica."
• Consider additional codes for associated complications such as scarring (e.g., L90.5 for scar conditions and fibrosis of skin) if documented.
