About 21208: Facial Bone Augmentation Surgery
Surgical augmentation of facial bone contour is reported when a surgeon adds structural support or projection to deficient facial skeletal areas.
This operation increases projection or support in an underdeveloped or deficient facial bone area. A surgeon may use an implant or graft material to augment the facial skeleton; the operative record should identify the treated site and the method used. Oral and maxillofacial, plastic, and craniofacial surgeons may perform the procedure in an operating room or another appropriate surgical setting.
Report the code for the facial-bone augmentation itself, not for reduction or a distinct reconstructive service. Document the anatomic site, the deficiency being treated, and the augmentation performed. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

21208 billing questions
How is augmentation distinguished from facial-bone reduction?
Report augmentation when the surgeon adds projection or structural support to facial bone. Code 21209 describes reduction, which removes or decreases facial bone prominence.
When should cheekbone augmentation be considered separately?
Code 21270 is the nearby code specifically associated with cheekbone augmentation. Select the code that matches the documented operative site and service.
Does the 90-day global include related follow-up care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be used for bilateral augmentation?
No. CMS identifies bilateral adjustment as inappropriate for this code's descriptor or anatomy.
When is assistant-at-surgery payment allowed?
Assistant-at-surgery payment is allowed only when medical necessity 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
