Other transepidermal elimination disorders

This code represents rare skin conditions characterized by the elimination of various substances, such as collagen, elastic fibers, or other cellular debris, through the epidermis. These disorders often manifest as papules, nodules, or plaques with central umbilication or ulceration, reflecting the transepidermal extrusion process.

Use this code for documented cases of transepidermal elimination disorders that are not specifically classified elsewhere in the L87 category. This includes conditions like reactive perforating collagenosis, elastosis perforans serpiginosa, or acquired perforating dermatosis when a more specific code is unavailable or the documentation indicates "other specified transepidermal elimination disorder." Documentation should clearly describe the pathological process of transepidermal elimination.

• Ensure the documentation specifies a transepidermal elimination disorder that doesn't fit a more specific L87 subcategory.
• Avoid using this code for general skin lesions or inflammatory dermatoses without evidence of transepidermal elimination.
• Consider sequencing this code after any underlying systemic disease that may be associated with the transepidermal elimination disorder, if applicable.
