About 21453: Closed mandibular fracture treatment with interdental fixation
Closed treatment of a mandibular fracture using interdental fixation, such as arch bars or wiring, when the fracture is managed without surgical exposure.
This service treats a broken lower jaw without surgically exposing the fracture site. The clinician aligns or stabilizes the fracture by securing the teeth or dental arches together with interdental fixation, commonly using arch bars or wiring. Oral and maxillofacial surgeons most often perform the procedure; surgeons in related specialties may also manage mandibular fractures in hospital or surgical settings.
Report 21453 when the documented treatment is closed and uses interdental fixation. Distinguish it from closed care without fixation and from procedures that use external fixation or open exposure. The note should identify the mandibular fracture and describe the closed reduction or stabilization and the interdental fixation used. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

21453 billing questions
How is 21453 different from 21450 or 21451?
21453 includes interdental fixation as the method of stabilizing the mandibular fracture. Codes 21450 and 21451 describe closed treatment without that fixation, with the distinction between them based on whether manipulation is performed.
Can 21453 be reported with open mandibular fracture treatment?
The treatment approach determines the code: 21453 is for closed treatment with interdental fixation. Open treatment codes apply when the fracture is surgically exposed and treated.
Should modifier 50 be used for bilateral mandibular fractures?
No. CMS identifies bilateral adjustment as inappropriate for 21453, so modifier 50 should not be used.
What documentation supports 21453?
Document the mandibular fracture and the closed treatment performed, including the use of interdental fixation. The record should make the treatment method distinguishable from closed care without fixation or open treatment.
How does the 90-day global period affect postoperative visits?
The global period includes the day-before preoperative visit and 90 days of related postoperative care. Those related services are included in the surgical global package.
When can an assistant-at-surgery be paid?
CMS allows assistant-at-surgery payment only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code.
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.
