Hand surgery
About 20827: Complete thumb replantation surgery
Reports microsurgical reattachment of a completely amputated thumb, including operative work to restore circulation and reconstruct injured structures.
This service covers surgery to reattach a thumb that has been completely severed. A hand surgeon or other surgeon with microsurgical expertise typically performs the urgent procedure in an operating room, using techniques to reconnect blood vessels and repair injured structures needed for thumb function. The code is specific to the thumb; a completely amputated nonthumb digit or a larger part of the hand has a different code in the replantation family.
Choose this code when the thumb was fully separated, rather than incompletely amputated with circulation requiring restoration. The operative report should establish the thumb as the replantation site, document complete separation, and describe the reconstruction performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. For bilateral service, modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
