About the L87 Code Range
ICD-10 code section L87 covers a group of rare skin conditions known as transepidermal elimination disorders, characterized by the body's process of expelling altered skin components through the epidermis.
This section includes specific codes for distinct disorders such as L87.0, which designates keratosis follicularis et parafollicularis in cutem penetrans—also called hyperkeratosis follicularis or perforating dermatosis. Code L87.1 identifies reactive perforating collagenosis, a condition involving reactive fibrous tissue proliferation sometimes referenced as acquired reactive perforating dermatosis. L87.2 covers elastosis perforans serpiginosa, another type of perforating dermatosis. For less common or unspecified variations, codes L87.8 and L87.9 are used, with synonyms including hyperkeratosis lenticularis perstans and general perforating dermatosis. These ICD-10 codes are essential for accurately documenting these specialized skin disorders in clinical and billing settings.
