D7140: Extraction, Erupted Tooth or Exposed Root
Definition
D7140 is the CDT code for a simple extraction of an erupted tooth or exposed root, removed by elevation or forceps.
Why it matters for the front desk
D7140 is the most common extraction code and is usually a basic service. A tooth that needs a flap, bone removal or sectioning is billed as a surgical extraction instead, so the code must match the clinical notes. Extractions also matter later: a patient who has a tooth removed before joining a plan may face a missing tooth clause when they want an implant or bridge.
