Thoracic surgery
About 21620: Partial sternum bone excision
Reports limited removal of sternal bone, including xiphoidectomy, for a focal problem such as persistent pain at the xiphoid process.
A surgeon removes a limited portion of the sternum. A familiar use is xiphoidectomy for persistent, localized pain arising from the xiphoid process; the procedure may also address another focal sternal bony problem when partial bone removal is performed. It is generally performed in an operating room by a thoracic or general surgeon, rather than as an office procedure.
Report the code when the operative report supports partial removal of sternal bone, not simply soft-tissue work or cleaning infected tissue. Documentation should identify the sternal site, the reason for surgery, and the extent of bone removed. Distinguish limited removal from sternal debridement and from a more extensive radical resection. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care for 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. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

21620 billing questions
When is this code appropriate for xiphoidectomy?
Use it when the surgeon removes part of the sternum at the xiphoid for a focal problem such as persistent localized xiphoid pain. The operative report should establish that sternal bone was removed.
How does this differ from sternal debridement?
This code represents partial sternal bone removal. When the documented service is debridement of the sternum, compare it with 21627 rather than selecting this code based only on the fact that bone was treated.
When should a more extensive sternum resection be considered?
Compare with 21630 when the operation involves radical resection of the sternum rather than limited removal. The operative report should support the extent of resection.
Can modifier 50 be reported for bilateral work?
No. CMS identifies bilateral adjustment as inappropriate for this code because of its descriptor or anatomy.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures performed in the same session are subject to the standard multiple-procedure reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation.
