As I have said before, there appears to be an exception to this for some hospital part b provider billings. I have not been able to learn the reason for this.The patient can only present the Medicare card and be done with it. The provider is not allowed to submit claims direct to the Medigap carrier .
One other possible exception to this could occur if the first claim a Part B provider submits for a service is denied and the provider then submits a second claim which is approved. I think I have read or heard that CMS will not crosswalk anything but the first claim for a service.
(I have had one instance where a provider submitted a claim 3 times to CMS before he got it approved but I doubt I still have MEOB's available see how the crosswalking might have worked in that situation.)
