TranS1 Inc. (Nasdaq:TSON), a medical device company focused on designing, developing and marketing products to treat degenerative conditions of the spine affecting the lumbar region, announced today that the company estimates that the total number of commercial and Federal Government lives covered for pre-sacral interbody fusion now exceeds 50 million, a significant milestone for pre-sacral interbody fusion coverage utilizing its proprietary AxiaLIF® implant. In addition, Medicare represents another 50 million covered lives divided into 15 different jurisdictions that typically cover Category I Codes that have assigned dollar values. CPT Code 22586, utilized for pre-sacral interbody fusion, was assigned a value by Medicare in November 2012.

"We are pleased to see the acceptance of the pre-sacral interbody fusion procedure in the payor community within the first six weeks of this year. This trend is a reflection of the strong clinical evidence and the growing interest for the procedure within the spine surgery community," stated Ken Reali, TranS1's President and CEO. A list of payors currently covering the procedure is available on TranS1's website.
