L87.9 — Transepidermal elimination disorder, unspecified
Is L87.9 billable?
Yes, but L87.9 is an unspecified code. L87.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, L87.9 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting L87.9 — the more specific alternatives are listed below.

How is L87.9 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to L87.9. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Disorder › elimination, transepidermal (of)
Excludes1 — never code together — inherited from L87
The conditions below can never be reported together with L87.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- granuloma annulare (perforating) (L92.0)
Excludes2 — not included here — inherited from Chapter 12
The conditions below are not part of L87.9, but a patient may have both at the same time. When documentation supports it, L87.9 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
