I have a vendor who submits new claims when the original claim denies. For example….a claim denies for a diagnoses billed with 99213 so the vendor submits a new claim (instead of a corrected claim) for 99213 with a different diagnoses. So basically the insurance company will have two office visits on file with different diagnoses. To me it makes more sense to send a corrected claim so that the incorrect diagnoses comes off of the patients record at the insurance company. What are your opinions on this?
