About 26992: Operative drainage of bone lesion
Reports operative drainage of a lesion within bone when the surgeon opens the affected site to evacuate its contents.
This service involves surgically opening a bone lesion to drain its contents. An orthopedic surgeon or another surgeon treating bone disease typically performs it in an operating room or other surgical facility. The operative report should identify the bone and lesion treated, describe the approach and drainage performed, and distinguish the target from a nearby soft-tissue collection or bursa.
Report the code when the operative work is drainage of the bone lesion, rather than diagnostic bone sampling or removal of a tumor. CMS assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple 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. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

26992 billing questions
How is this different from a bone biopsy?
This code describes operative drainage of a bone lesion. A bone biopsy code is used when the service is obtaining tissue for diagnosis rather than draining the lesion.
What documentation supports reporting this code?
Document the bone and lesion treated, the operative approach, and the drainage performed. The note should make clear that the target was within bone, not a bursa or adjacent soft tissue.
Can an assistant surgeon be reported?
Assistant-at-surgery payment is allowed only when the record documents medical necessity. Co-surgeons and team surgery are not permitted for this code.
Does modifier 50 apply when lesions are treated on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
