CPT® Code 0349T

Radiologic examination, radiostereometric analysis (RSA); upper extremity(ies), (includes shoulder, elbow, and wrist, when performed)

Radiostereometric analysis (RSA) is a specialized radiologic examination technique that utilizes two X-ray images taken from different angles simultaneously. This method employs previously implanted tantalum beads as reference points, which are crucial for creating a precise three-dimensional image. The primary purpose of RSA is to detect any skeletal movement or changes in the position of an implant, providing valuable insights into the stability and integrity of orthopedic devices. The tantalum beads can be inserted directly into the bone surrounding an implant or can be mounted in a fixed position, such as within a spinal cage that is placed in front of the patient. RSA is particularly useful for assessing and monitoring various conditions, including the integrity of growth plates, the stability of total joint replacement implants, and the effectiveness of spinal fusions. Additionally, RSA can be employed for kinematic studies of the knee, spine, and shoulder, allowing for a comprehensive evaluation of joint function and movement. The CPT® code 0349T specifically pertains to the radiostereometric analysis of the upper extremities, which includes the shoulder, elbow, and wrist, distinguishing it from other codes that cover different anatomical regions.
