Around 2017 we started having issues with Medrisk. They told us they'd except the new PT eval codes and they did pay them up until October 2017 - then they started denying them and said they'd only except the old code 97001. We continuously resubmit several corrected claims for 2 years and they give a different explanation each time or say the claim isn't on file - then it takes them another 30-60 days to reprocess. And they keep doing this over and over again....I'm guessing they just hope we'll give up. We also have several treatments that are unpaid - they do the same thing, they say the claim isn't on file, or the provider name and provider number are missing (when they're not), or that we need to submit directly to the carrier (and the carrier has already paid Medrisk for the visit). I'm so fed up with fighting with them because each time I call no one knows what they're talking about. I can't believe they're able to get away with operating this way! I make it a point to contact them every month and we've managed to get some of our claims paid but I still have at least 10 claims I need paid.
