About 21390: Orbital floor fracture repair with implant
Reports operative reconstruction of an orbital floor blowout fracture through a periorbital approach when the surgeon places an implant to support the repaired floor.
Code 21390 covers operative repair of an orbital floor blowout fracture through an incision around the orbit, with an implant used to support the reconstructed floor. The surgeon exposes the fracture, addresses displaced orbital tissue as needed, and places the implant across the defect. This repair is typically performed by an oculoplastic, oral and maxillofacial, plastic, or facial trauma surgeon in an operating room after facial trauma has caused a floor defect or orbital tissue displacement.
Choose this code when the documented repair uses the periorbital approach and includes an implant. The operative report should identify the fracture and side, describe the approach and repair, and document implant placement. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. 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. For bilateral repair, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

21390 billing questions
How does 21390 differ from 21386?
Both involve a periorbital approach to orbital floor fracture repair. Report 21390 when an implant is placed; 21386 describes the periorbital repair without that implant distinction.
When would 21395 be considered instead?
21395 is the related periorbital repair code when bone graft is used. The operative report should support whether the reconstruction used an implant or bone graft.
Can the implant placement be reported as a separate fracture repair?
The implant is part of the repair represented by 21390. Do not report another orbital floor fracture repair code for the same repair.
How is bilateral repair reported?
When the service is performed on both sides, report modifier 50. CMS pays bilateral procedures at 150% under the stated rule.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
What documentation supports co-surgeon payment?
Co-surgeon payment requires supporting documentation. The operative record should substantiate the surgeons' distinct roles in the repair.
