Official Description

Replantation, digit, excluding thumb (includes distal tip to sublimis tendon insertion), complete amputation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The replantation procedure described by CPT® Code 20822 is indicated for patients who have experienced a complete amputation of a digit, excluding the thumb. This procedure is typically performed in cases where the amputation occurs between the fingertip and the attachment of the finger to the palm. The indications for this procedure may include:

  • Complete Amputation of a Digit The primary indication for this procedure is the complete severance of a finger, necessitating surgical intervention to restore functionality and appearance.
  • Traumatic Injury Patients who have suffered traumatic injuries, such as those resulting from accidents or severe lacerations, may require replantation to salvage the digit.
  • Reattachment Feasibility The procedure is indicated when the amputated digit is suitable for reattachment, meaning that the tissue is viable and the amputation occurred within a specific time frame.

2. Procedure

The replantation procedure involves several critical steps to ensure successful attachment and healing of the digit. The procedural steps include:

  • Preparation and Anesthesia The patient is placed under general anesthesia to ensure comfort and pain management throughout the procedure. This is essential for allowing the surgeon to perform intricate tasks without causing distress to the patient.
  • Tissue Removal The surgeon begins by carefully removing any damaged or necrotic tissue surrounding the amputation site. This step is crucial as it prepares the area for the reattachment of the digit and helps to minimize the risk of infection.
  • Bone Trimming The ends of the amputated bones are then trimmed to create a clean surface for rejoining. This step is vital as it facilitates the alignment of the soft tissues and ensures a more straightforward suturing process.
  • Suturing of Structures Once the bones are aligned, the surgeon proceeds to suture together the essential structures, including arteries, veins, nerves, muscles, and tendons. This meticulous process is critical for restoring blood flow, sensation, and movement to the digit.
  • Skin Grafting In cases where there is insufficient skin coverage over the reattached digit, a graft may be applied to cover the exposed areas. This helps to protect the underlying structures and promotes healing.
  • Free-Tissue Transfer If there are uncovered nerves, tendons, or joints, the surgeon may perform a free-tissue transfer, which involves using tissue from another part of the body along with its blood supply to cover these areas.
  • Layered Closure Finally, the amputation site is closed in layers, ensuring that all tissues are properly aligned and secured. This layered closure technique is important for optimal healing and reducing the risk of complications.

3. Post-Procedure

After the replantation procedure, patients typically require careful monitoring and follow-up care to ensure proper healing and function of the reattached digit. Post-procedure care may include pain management, wound care, and physical therapy to restore movement and strength. Patients are advised to keep the surgical site clean and dry, and to follow any specific instructions provided by the healthcare team regarding activity restrictions and signs of potential complications, such as infection or impaired blood flow. Regular follow-up appointments are essential to assess the healing process and to make any necessary adjustments to the treatment plan.
