Oral & Maxillofacial Surgery in the ASC: CPT Code Reference

Oral and maxillofacial surgeons treat conditions of the jaws, face, mouth, and related structures, much of it on an outpatient basis. The most relevant CPT codes cluster in two ranges: the head and facial bone range, 21000-21499, which covers procedures on the bones of the face and jaw such as 21248 (reconstruction of the jaw), and the 41800-41899 range for dentoalveolar structures. We have mapped 179 ASC-relevant CPT codes to this specialty.

Coverage in an ASC depends on where a code sits in the CMS addenda. Codes on Addendum AA are on the ASC Covered Procedures List, meaning Medicare pays them when performed in an ASC, while Addendum EE codes are excluded. Confirming a code's addendum status before scheduling is the most reliable way to avoid billing surprises.

Are oral and maxillofacial surgery procedures performed in an ASC?

Yes. Many oral and maxillofacial procedures are outpatient and can be performed in an Ambulatory Surgery Center. Whether Medicare pays for a specific procedure in an ASC depends on the code's CMS addendum status: codes on Addendum AA are on the ASC Covered Procedures List, while Addendum EE codes are excluded from ASC payment. Confirm a code's status before scheduling.

What CPT codes does oral and maxillofacial surgery use?

The specialty's ASC-relevant codes fall mainly in two ranges. The 21000-21499 range covers head and facial bone procedures such as 21248 (reconstruction of the jaw) and 21210 (face bone graft), and the 41800-41899 range covers dentoalveolar procedures, including the unlisted code 41899. Our dataset maps 179 ASC-relevant codes to this specialty.

How do I bill an unlisted oral surgery code like 41899?

Unlisted codes such as 41899 (unlisted procedure, dentoalveolar structures) have no assigned descriptor detail, so payers typically require an operative report and a written description of the work performed. These claims often go to manual review. DataLily's procedure library tracks CPT-specific prior-authorization and documentation requirements to help teams prepare the right support before submission.
