Ask Dr. Z

I looked back into the archives and want to make sure this is the correct/current information. Physician is doing a tunnel catheter replacement. He says the balloon was inflated and gently advanced and retracted to disrupt the fibrin sheath at the level of the SVC and cavoatrial junction. Should I use unlisted for fibrin sheathoplasty? Medicare will not cover that code even when we send documentation to support. I have gotten commercial payers to cover it. My radiologist asked me to check with you again on how to code these.
