CPT® Code 20822

The procedure described by CPT® Code 20822 involves the replantation of a digit, specifically excluding the thumb, that has been completely amputated. This procedure is performed when a finger has been severed from the hand, typically occurring between the fingertip and the point where the finger connects to the palm. The replantation process is intricate and requires the physician to work under general anesthesia to ensure the patient is comfortable and pain-free during the operation. Initially, any damaged or necrotic tissue surrounding the amputation site is meticulously excised to prepare for the reattachment. Following this, the ends of the amputated bones are carefully trimmed to facilitate a more straightforward alignment and connection of the soft tissues surrounding the wound. This preparation is crucial as it aids in the subsequent suturing of vital structures, including arteries, veins, nerves, muscles, and tendons, which are essential for restoring function and sensation to the digit. In cases where there is a lack of skin coverage, a graft may be utilized to cover the exposed areas. Additionally, any uncovered nerves, tendons, and joints may require a free-tissue transfer, which includes the necessary blood supply through its accompanying artery and veins. Finally, the amputation site is closed in layers to promote optimal healing and recovery.
