    ICD-10-CM Code For Transepidermal Elimination Disorders: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group L87 includes conditions characterized by transepidermal elimination such as elastosis perforans serpiginosa and related disorders where dermal material is expelled through the epidermis. These ICD-10-CM diagnosis codes are used to document clinical presentations with characteristic skin lesions, document disease severity and distribution, and capture related complications or comorbid skin conditions. Accurate coding within the ICD-10-CM L87 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM L87: Transepidermal Elimination Disorders Overview

    Transepidermal elimination disorders are skin conditions characterized by the extrusion of dermal material through the epidermis, often involving altered connective tissue or inflammatory debris. These disorders affect the integumentary system and can present with papules, plugs, or crateriform lesions. Accurate coding matters for reimbursement because it links clinical documentation to the specific diagnosis and supports appropriate claim adjudication.

    Typical Clinical Scenarios

    • An adult patient presents to dermatology with a several-month history of pruritic, dome-shaped papules with central keratotic plugs on the extensor surfaces; biopsy shows elimination of altered collagen fibers through the epidermis consistent with reactive perforating collagenosis. The lesions are chronic with intermittent flares that prompt outpatient management and documentation of a transepidermal elimination disorder. Typical codes: L87.0.
    • A patient with poorly controlled diabetes mellitus arrives to urgent care with multiple new umbilicated nodules and central crusting that developed over weeks, some of which are painful and secondarily infected. Clinical examination and history of systemic disease suggest acquired perforating dermatosis related to underlying metabolic disease, leading to assignment of a transepidermal elimination disorder diagnosis. Typical codes: L87.1, L87.2.
    • An elderly patient with long-standing chronic kidney disease on hemodialysis reports numerous hyperkeratotic papules and plaques with transepidermal elimination noted on prior biopsy; the skin findings are now contributing to recurrent skin breakdown and localized cellulitis. The presentation is a complication of the chronic dermatosis requiring coordination of wound care and infection management, so a transepidermal elimination disorder code is used alongside codes for the complication. Typical codes: L87.2, L87.8.
