Wiki ASC GI Use of Modifier 51

[Coleene]

We are an ASC and have been using modifier 51 to the second procedure when we file a claim for a 43239 and 43450-51. Recently we received an EOB from Medicare that reversed the 51 to the 43239. They did not make any corrections to the EOB. They also moved the 51 to the 43235 when it was billed with the 43450. Can anyone tell me if Medicare does not except the 51 modifier for multiple procedures and if any one else is having this happen?

Medicare does not really want you to add the 51 modifier. They already understand it is multiple procedures. They will add the 51 themselves when they process the claim. We never add a 51 modifier to a Medicare claim.
