L05.0 — Pilonidal cyst and sinus with abscess
Is L05.0 billable?
No — L05.0 is a non-billable header code. L05.0 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 2 billable codes beneath L05.0.
