On April 1, 2015, Wisconsin Physicians Service Insurance Corporation (WPS Medicare) issued a proposed non-coverage Local Coverage Determination (LCD) for minimally invasive sacroiliac joint fusion (MIS SIJ fusion). WPS Medicare is the Medicare Administrative Contractor (MAC) covering Michigan, Indiana, Iowa, Nebraska, Missouri and Kansas. ISASS drafted a comment letter urging WPS Medicare to review the ISASS coverage criteria on the procedure and all relevant literature in order to develop a comprehensive coverage policy. The ISASS comment letter was submitted on June 17 and ISASS subsequently sent an advocacy action alert email to members in the WPS Medicare jurisdiction urging them to send individual letters to WPS voicing their concerns. The comment period ends on June 27 and WPS Medicare should issue a final coverage decision after reviewing all comments.
