CPT® Code 0561T

1. Indications

The 3D-printed anatomic guide described by CPT® Code 0561T is indicated for use in various surgical procedures where precise anatomical alignment is critical. The following conditions and scenarios may warrant the use of such a guide:

• Osteotomies - Surgical procedures involving the cutting of bone, particularly in cases where cancer resection is necessary, to ensure accurate removal of affected tissue.
• Harvesting Autologous Bone Grafts - Procedures that require the collection of bone from one site in the patient’s body for use in reconstructive surgery, where precise placement is essential for successful outcomes.

2. Procedure

The procedure for creating a 3D-printed anatomic guide involves several detailed steps to ensure accuracy and effectiveness:

• Consultation and Imaging Review - Initially, a consultation is conducted to discuss the surgical needs related to the anatomic guide. Following this, previously acquired imaging data, such as CT or MRI scans, is reviewed to determine if it is sufficient for creating an accurate guide.
• Segmentation and Digital Representation - Dedicated segmentation software is utilized to create a computer design file. This software separates the target anatomy from surrounding structures, converting the targeted anatomy into a segmented digital representation that facilitates virtual surgical planning.
• Planning Cutting Planes - The planned cutting planes are digitally placed in the desired locations on the segmented anatomy. This step is crucial as it defines the exact areas where surgical interventions will occur.
• Guide Design and Export - All the data, including the planned cutting planes, is exported to software that designs the cutting guide. This guide is tailored to match the contours of the patient’s anatomy, ensuring that the cutting openings align with the planned surgical planes.
• Final Design Review - The finished guide design file is digitally overlaid on the segmented anatomy to verify accuracy. The guide is uniquely identified for the patient, ensuring that it is specific to their anatomical needs.
• 3D Printing - The design file is converted into a format compatible with the 3D printer. The guide is printed using biocompatible and sterilizable materials, which are essential for surgical use.
• Post-Printing Review - Once printed, the guide is cleaned and reviewed for any specific design considerations before surgery. Photographs of the final guide are taken for documentation purposes.

3. Post-Procedure

After the creation of the 3D-printed anatomic guide, it is essential to ensure that the guide is thoroughly cleaned and sterilized before use in surgery. The final review of the guide should confirm that it meets all design specifications and is free from defects. The guide is then prepared for surgical use, where it will assist the surgeon in achieving precise anatomical alignment during the procedure. Proper documentation, including photographs of the guide, should be maintained for compliance and future reference.
