Op report reads:

The bile duct was deeply cannulated with the short-nosed traction sphincterotome. Contrast was injected. The upper third of the main bile duct contained a single localized stenosis. Dilation with the 8mm balloon resulted in 70 percent obliteration. Five stents were removed from the common bile duct using a snare. Four stents, one 10F and three 7F were placed since the stricture was still present (about 50%).

Would you bill 43269 or 43268 multiple times? I billed 43268 only X 4. Is this correct?
