Some of our patients come in for their 6month office visit and have their pacemaker or ICD checked on the same day. It is 2 different appts, that have obviously their own claim. I put a modifier 25 on the E/M. Both visits have always been paid, but now with ICD-10 I got a rejection on the office visit stateing DX codes Z95.0 (presence of pacemaker) and Z45.018 (encounter for adjustment) is not passing iCES edits and was rejected. This was billed to Medicare plus Blue advantage. Has anyone else experienced this and if so how do i fix it? My solution was to send back the E/M claim without Z95.0.
