Wife was sent for bloodwork that does not take medicare assignment. We are new to medicare and shame on them because we probably should have done it there. We were shocked when the facility told us we had to pay the cost of 400 dollars for the tests because they didn't do medicare. I believe the test were routine and have found out they probably wouldn't pay anyway. But we have a medigap plan also from mutual of omaha and thinking shouldn't they paying for what medicare is not?
