About 28005: Foot bone cortex incision
Report this operation when a surgeon incises the cortex of a foot bone to treat a process such as osteomyelitis or bone abscess.
CPT 28005 describes an operative incision through the cortex of a foot bone to treat a bone process such as osteomyelitis or a bone abscess. An orthopedic or foot-and-ankle surgeon, including a podiatric surgeon, typically performs it in an operating room, exposing the involved bone for treatment. The target is bone itself, rather than an overlying bursa, fascia, joint lining, or soft-tissue mass.
Document the bone and site involved, the diagnosis and operative findings, and the bone-directed work performed. Medicare assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

28005 billing questions
How is 28005 distinguished from foot infection drainage codes?
Use 28005 when the operative target is the bone cortex, such as for osteomyelitis or a bone abscess. Codes 28002 and 28003 concern treatment of foot infection rather than incision of bone cortex.
Is modifier 50 appropriate for this code?
No. CMS identifies bilateral adjustment as inapplicable because the descriptor or anatomy makes modifier 50 inappropriate.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is 28005 paid when another procedure is done in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for 28005. Co-surgeons and team surgery are not permitted.
