About 21366: Complex malar fracture repair with graft
Open repair of a complex cheekbone fracture with bone grafting, reported when reconstruction requires graft support or replacement of missing bone.
This service is an open reconstruction of a complex malar, or cheekbone, fracture using a bone graft. It is typically performed by an oral and maxillofacial surgeon, facial plastic surgeon, or other surgeon treating facial trauma, often in an operating room. The fracture may involve the malar bone and its connections to surrounding facial bones; the operative report must support a complex injury and graft-assisted repair, not simply an isolated depressed cheekbone fracture.
Report the code when the surgeon opens the fracture site and uses a graft as part of the complex malar repair. Documentation should identify the fracture pattern, open approach, graft placement, and treated side. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery and co-surgeon payment are permitted; team-surgery payment is not.

21366 billing questions
How does this differ from 21365?
Both describe open treatment of a complex malar fracture, but 21366 is the graft-assisted service. Use 21365 when the documented complex repair does not include a bone graft.
Is the bone graft part of this service?
Yes. The code identifies complex malar fracture repair with grafting; it is not the code for the same repair without a graft.
When is modifier 50 appropriate?
Use modifier 50 for bilateral treatment when both sides are treated. CMS payment for the bilateral procedure is 150%.
What should the operative note establish?
Document the complex malar fracture pattern, open repair, graft placement, and laterality. The record should distinguish this repair from treatment of an isolated depressed malar fracture or zygomatic arch fracture.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%. The code has a 90-day global period for related postoperative care.
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.
