ICD-10 Code L87.9 – Transepidermal Elimination Disorder, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L87.9 – Transepidermal elimination disorder, unspecified
What it is
L87.9 identifies a transepidermal elimination disorder when the record does not specify the exact type. These conditions involve skin material being expelled through the epidermis, but the documentation is nonspecific.
Clinical signs
Clinical features vary; refer to documentation. You may see papules, nodules, or crusted lesions with a history or biopsy description suggesting transepidermal elimination.
When to use this code
Use L87.9 when the clinician documents a transepidermal elimination disorder but does not name a more specific diagnosis. It also fits when pathology or dermatology notes confirm the process, yet the exact subtype is not stated. Check documentation if the record is unclear.
Do not use for
Do not use L87.9 if the chart identifies a specific perforating disorder or another defined skin condition. Do not assign it for nonspecific rash or lesion descriptions without documentation of transepidermal elimination.
Coding tip
Query for the exact subtype whenever possible; unspecified coding should be your last choice.
