About 28304: Midfoot tarsal bone osteotomy
A surgeon cuts and reshapes a midfoot tarsal bone, other than the heel or talus, to correct alignment or structural deformity.
This service involves a planned cut in a midfoot tarsal bone, such as a cuneiform, navicular, or cuboid, to change its alignment or shape. Orthopedic foot-and-ankle surgeons and podiatrists perform these procedures to address structural deformity or abnormal foot mechanics, commonly in an operating room. The operated bone distinguishes this service from osteotomy of the calcaneus, talus, or a metatarsal. A tarsal osteotomy with autograft is reported with a different code.
Select this code when the operative work is a midfoot tarsal osteotomy without the autograft service represented by 28305. The operative report should identify the bone and side, the condition being corrected, the osteotomy and correction performed, and whether graft was used. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session multiple procedures, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 bilateral procedures are paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

28304 billing questions
How does 28304 differ from 28305?
Both describe osteotomy of a midfoot tarsal bone other than the calcaneus or talus. Use 28305 when the tarsal osteotomy includes autograft; 28304 is the option without that graft service.
Which bone determines whether this code applies?
The osteotomy must involve a midfoot tarsal bone, such as a cuneiform, navicular, or cuboid. A calcaneal, talar, or metatarsal osteotomy belongs to a different code.
What should the operative report document?
Document the specific bone and side, the deformity or alignment problem, the osteotomy and correction performed, and whether autograft was used.
How is a bilateral procedure handled under the CMS facts?
A bilateral procedure reported with modifier 50 is paid at 150%.
What postoperative care is included in the global period?
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?
Assistant-at-surgery payment may be made. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
