Radiostereometric analysis (RSA) is a specialized imaging 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 representation of skeletal structures. The primary purpose of RSA is to detect any movement of bones or changes in the positioning of implants over time. The tantalum beads can be inserted directly into the bone surrounding an implant or can be affixed in a stable position to a spinal cage that is placed in front of the patient during the imaging process. This advanced imaging technique is particularly valuable in assessing and monitoring the integrity of growth plates, evaluating the stability of total joint replacement implants, and examining spinal fusions. Additionally, RSA is utilized for kinematic studies of various joints, including the knee, spine, and shoulder. The specific CPT® code 0348T is designated for radiostereometric analysis of the spine, which encompasses the cervical, thoracic, and lumbosacral regions when performed. This code is distinct from 0349T, which pertains to RSA of the upper extremities, and 0350T, which is used for RSA of the lower extremities.

Radiostereometric analysis (RSA) is indicated for various clinical scenarios where precise measurement of skeletal movement or implant positioning is necessary. The following conditions may warrant the use of this imaging technique:
The procedure for radiostereometric analysis (RSA) involves several critical steps to ensure accurate imaging and assessment. The following outlines the procedural steps:
After the radiostereometric analysis (RSA) procedure, patients may be monitored for any immediate post-procedural effects, although RSA is generally non-invasive and well-tolerated. The results of the analysis will be compiled and interpreted by a qualified healthcare professional, who will discuss the findings with the patient. Follow-up appointments may be scheduled to monitor the condition being assessed, particularly in cases involving joint replacements or spinal fusions, to ensure ongoing stability and integrity. Additional imaging or interventions may be recommended based on the results of the RSA.

| 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. |
