About 20824: Complete thumb replantation
Reports surgical reattachment of a completely detached thumb after traumatic amputation, typically performed by a hand surgeon using microsurgical techniques.
Code 20824 represents surgical reattachment of a completely separated thumb after traumatic amputation. In the operating room, a hand, orthopedic, or plastic surgeon restores continuity of the amputated part, typically using microsurgical techniques to reconnect structures needed for viability and function. This is an emergency limb-preservation procedure generally performed in a hospital setting.
Choose this code when the thumb was fully detached, rather than remaining partly attached. The operative report should identify the thumb, document complete separation, and describe the replantation performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session procedures, the highest-valued procedure is paid in full and others at 50%. Modifier 50 identifies a bilateral procedure, paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
