What 20520 covers
This service covers straightforward extraction of a foreign object located in muscle or a tendon sheath. A physician or other qualified practitioner may perform it in an office, emergency department, or outpatient procedure setting. Examples include removing a retained splinter or fragment when the object is in the specified tissue and can be removed without a deep or complicated procedure. The tissue location and degree of difficulty distinguish this service from removal of an object confined to subcutaneous tissue.
Report the service when the operative or procedure note supports both the muscle or tendon-sheath location and a simple removal. Document the object’s location and the work needed to extract it; use the deep or complicated family level when those circumstances are supported instead. The service has a 10-day global period, so related postoperative visits during that period are included. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.

20520 billing questions
How do I distinguish this code from 20525?
Use this code for a simple removal from muscle or a tendon sheath. Use 20525 when the removal is deep or complicated.
What if the foreign object is only in subcutaneous tissue?
Consider 10120 for a simple removal from subcutaneous tissue or 10121 for a complicated removal. The tissue location, not just the object type, guides code selection.
Can the access incision be billed separately?
Do not separately report an incision that is simply the access needed to remove the foreign object. The service is the removal, with the operative note supporting its location and complexity.
Should modifier 50 be appended for removal on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Are postoperative visits separately payable during the global period?
Related postoperative visits during the 10-day global period are included in the procedure payment.
Can an assistant surgeon or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.
