OMG, don't get me started on this. Could go on and on about all the **** I've dealt with, particularly this year. The PPOs have gone insane in my area with their pre-auth games. We call the insurance to request pre-auth, are told we don't need it for the diagnosis code, then receive denials of payment for not having pre-auth. Of course, the insurance won't give us any feedback until end of treatment, so we don't even get a denial until several weeks after patient is done. We will call two different departments in the insurance company and one operator tells us pre-auth needed, the other says no need. We've even had them on 3 way calls giving us conflicting information. UM dept says no pre-auth, but claims dept on same call says it's needed. I stopped listening to the operators and UM dept and go directly to the websites. If the website says preauth required for IMRT, I refuse to treat patient until I have one. I make patient call as well. If I verify no preauth needed on website I still ask for a pre-determination. I also started just reflexively doing 3D vs. IMRT planning comparisons on all cases.
