I just started billing for a Rural Health Clinic and we sent our claims to Medicare for processing and they were rejected because we filled the ub-04 form out incorrectly. We fixed the form and resent the claim and Medicare is saying that it is a duplicate claim and we need to void the claim. I am not quite sure how to go about doing that. Does anyone have any suggestions for me
Since IOP is outpatient you could try 833. The middle 3 is to indicate "Outpatient".
