We have three AR people in my office that often will change my coding. If the claim denies for any reason (ie: request for med records) if the claim has modifiers listed for pacemakers or defibrillators or TAVRS the AR people first just remove the modifiers and rebill the claim instead of sending the records are calling insurance company to get reason for denial if its not for med records and then when claim denies again I receive it back with a note from them that I billed the claim incorrectly. Does anyone else have this problem and if so how to I handle this situation?
