What 28485 covers
This service involves surgically exposing a fractured metatarsal and reducing the bone through an open approach. The surgeon may stabilize the reduction with internal fixation, such as screws or a plate, when needed. Orthopedic and podiatric surgeons commonly perform the procedure in an operating room for fractures requiring open treatment rather than closed reduction or percutaneous fixation.
Select the code when the operative report documents open treatment of a metatarsal fracture. Report each metatarsal treated and document the specific bone, fracture, open approach, reduction, and fixation performed. Medicare assigns a 90-day global period, including 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 others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

28485 billing questions
How is 28485 different from closed treatment of a metatarsal fracture?
Use 28485 when the fracture is treated through an open surgical approach. Closed treatment codes apply when the fracture is managed without surgically exposing the fracture site.
How many units should be reported?
The code is reported for each metatarsal treated. The operative documentation should identify the metatarsal or metatarsals that underwent open treatment.
Should modifier 50 be used for fractures in both feet?
No. CMS identifies bilateral adjustment as inappropriate for this code; report the service according to the each-metatarsal unit.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be paid for this procedure?
Medicare does not pay an assistant at surgery for this code. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.
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%.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
