What 28107 covers
A foot-and-ankle orthopedic surgeon or podiatric surgeon removes or curettes a bone cyst or benign tumor in a tarsal or metatarsal bone and uses donor bone material to fill the resulting defect. The service is generally performed in an operating room or other surgical facility. The code is specific to these foot bones; a lesion in the talus or calcaneus belongs to a different code group.
Select this code when the operative report identifies the tarsal or metatarsal bone treated, the lesion removal or curettage, and use of an allograft. The grafting work is represented in the service, so do not separately report a graft procedure for that same defect. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during the following 90 days. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

How to choose
- 28106Foot bone lesion
- Use 28107 when an allograft fills the defect; 28106 is the corresponding tarsal or metatarsal lesion service with an autograft.
- 28104Bone lesion excision
- This code identifies allograft use for the tarsal or metatarsal defect. Code 28104 describes lesion removal in those bones without that graft distinction.
- 28103Foot bone lesion
- Both involve grafting a bone lesion, but 28103 is for the talus or calcaneus; 28107 is for another tarsal or metatarsal bone.
28107 billing questions
How is this code distinguished from 28106?
Both apply to a tarsal or metatarsal bone lesion, but 28107 is for use of an allograft. Code 28106 is the corresponding service when an autograft is used.
Can the allograft be billed separately?
The allograft use is included in this service for the treated bone defect. Do not separately report a graft procedure for that same defect.
What documentation supports code selection?
Document the specific tarsal or metatarsal bone, removal or curettage of the cyst or benign tumor, and use of an allograft to fill the defect.
Can modifier 50 be appended when both feet are treated?
No. CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
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.
