What 21085 covers

This service covers taking the impression and preparing an oral surgical splint for a patient undergoing oral or maxillofacial surgery. Oral and maxillofacial surgeons and prosthodontists may provide it in an office or facility setting. A common clinical context is orthognathic surgery, where a custom splint helps transfer or maintain a planned relationship between the jaws during treatment.

Report 21085 when the documented service is for an oral surgical splint, rather than an obturator, speech aid, or other maxillofacial prosthesis. The record should identify the surgical purpose and support the impression and preparation performed. The code has a 10-day global period, which includes related postoperative visits during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

21085 billing questions

How is 21085 different from 21076?

Use 21085 for an oral surgical splint. Code 21076 describes impression and preparation for a surgical obturator, a different type of maxillofacial prosthesis.

Does 21085 cover both the impression and splint preparation?

Yes. The service combines impression-taking and preparation of the oral surgical splint; document the work performed and its surgical purpose.

Can modifier 50 be used for a splint involving both sides?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.

What postoperative care is included?

Related postoperative visits during the 10-day global period are included.

When can an assistant-at-surgery be paid?

Only when medical necessity for the assistant is documented. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
