CPT 0347T: Tantalum Marker Placement for Implant Motion and Wear Assessment

CPT code 0347T covers placement of multiple tantalum beads in bone and acquisition of a two-dimensional image to measure motion, quality, and wear of an implant or prosthesis. This code supports advanced implant surveillance and research-quality assessments of prosthetic performance, with implications for postoperative management, device surveillance, and outcomes measurement nationwide. It matters both clinically—by providing objective data on implant behavior—and administratively, as payers consider coverage for specialized imaging and marker placement linked to device evaluation.

Key payers in the scope of typical coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for marker-assisted implant assessment, typical settings where the service is performed, and what to expect in payer review. The publication outlines benchmarking topics and policy considerations relevant to coverage decisions, coding nuances for operations involving implants, and patterns in utilization when available. Data not available in the input for detailed payer-specific rates, associated taxonomies, and ICD-10 diagnosis mappings is noted for transparency.

This piece provides clinicians, billing professionals, and policy analysts a concise reference to the clinical purpose of CPT code 0347T, the service setting, and the payer landscape to inform coding, billing, and coverage conversations at the national level.

Billing Code Overview

CPT code 0347T describes the placement of multiple tantalum beads in the interstitial spaces of bones with acquisition of a two-dimensional image to measure the motion, quality, and wear of an implant or prosthesis. This procedure is a marker placement and imaging service intended to enable precise assessment of prosthetic or implant kinematics and wear characteristics.

Service type: Implant marker placement with associated imaging to evaluate implant motion, quality, and wear
Typical site of service: Ambulatory surgical center or hospital operating/procedure room where sterile marker placement and intraoperative or perioperative imaging can be performed

Clinical Context

A typical patient is a 62-year-old individual with a painful, loosening total hip or knee arthroplasty who presents for evaluation of implant micromotion and wear. The orthopedic surgeon elects to perform tantalum bead implantation (marker placement) in the periprosthetic bone during a brief operative procedure under regional or general anesthesia. Multiple small tantalum beads are placed in the interstitial bone surrounding the implant to serve as radiographic fiduciary markers. After bead placement, a two-dimensional radiographic image series (often standing AP and lateral views) is obtained to document the beads and prosthesis position. These images are used to perform radiostereometric analysis (RSA) or similar image-based methods to measure micro-motion, migration, and wear of the implant over time.

The clinical workflow: preoperative evaluation and consent; intraoperative sterile placement of tantalum beads around the implant; immediate postoperative radiographs to verify bead positions and implant alignment; documentation of bead count and locations in the operative note; scheduling of follow-up radiographs or RSA studies at defined intervals (typically 6 weeks, 3 months, 6 months, 1 year, then yearly) to quantify implant migration and wear; interpretation and reporting by the orthopedic surgeon or radiologist with measurements compared to baseline images.
