About 21497: Interdental wiring for nonfracture stabilization
Interdental wiring stabilizes the jaws through dental fixation for a documented nonfracture indication, rather than as part of coded fracture treatment.
This service involves placing wire between teeth to hold the jaws in a stable position for a nonfracture indication. It is generally performed by an oral and maxillofacial surgeon, often in a facility setting. The clinical record should identify why interdental stabilization is needed and describe the wiring performed; the indication should not be a fracture treated under a fracture-specific code.
Report the service when the documented work is interdental wiring for a nonfracture condition, not merely because wires are present as part of another procedure. The 90-day global period includes the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed 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 not appropriate for this code. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

21497 billing questions
How is this distinguished from mandibular fracture treatment?
This code is for interdental wiring with a nonfracture indication. When the wiring is part of treatment for a mandibular fracture, select the fracture-specific code that matches the treatment approach.
What documentation supports reporting this code?
Document the nonfracture indication, the need for interdental stabilization, and the wiring work performed. The record should make clear that the service is not being reported as fracture treatment.
Can the wiring be separately reported with another operation?
The code represents the interdental wiring service itself. Report another procedure only when its distinct work is documented and separate reporting is supported by the applicable coding rules.
Can modifier 50 be used when both sides are treated?
No. CMS identifies bilateral adjustment as inappropriate for this code; report the service without modifier 50.
When is an assistant-at-surgery payment allowed?
CMS permits assistant-at-surgery payment only when medical necessity is documented. Co-surgeon and team-surgery payment are not permitted.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
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.
