Transepidermal elimination disorder, unspecified

This code signifies a group of rare skin conditions characterized by the elimination of various substances (e.g., collagen, elastic fibers, lipids) through the epidermis. These disorders often present with papules, nodules, or plaques, and can be primary or associated with systemic diseases.

Use this code when the medical record documents a transepidermal elimination disorder, but the specific type (e.g., reactive perforating collagenosis, elastosis perforans serpiginosa) is not specified by the provider. This code is appropriate when the diagnostic workup is incomplete or the provider has not yet reached a more definitive diagnosis.

• Avoid using this code if a more specific transepidermal elimination disorder is documented.
• Query the provider for further specificity if possible to achieve a more precise diagnosis.
• Consider co-reporting underlying systemic conditions if they are documented as associated with the transepidermal elimination disorder.
