In Ancillary Affiliated Health Servs. v. Shalala, 165 F.3d 1069, 1071 (7th Cir.1998), Medicare had overpaid provider Ancillary Affiliated. Ancillary Affiliated wished to repay the overpayment over a period of 18 months, but the HCFA chose to withhold all reimbursement checks until the overpayment had been recouped in full. Id. at 1069-70. Although Ancillary Affiliated was pursuing a Due Process claim, the Seventh Circuit determined that there was no subject matter jurisdiction because " `both the standing and the substantive basis for the ... claims' stemmed from the Medicare Act." Id. at 1070. The Seventh Circuit affirmed the dismissal for lack of jurisdiction.
