Court of Appeals for the Seventh Circuit December 1, 1995, 18-1321 (Central States, Southeast and Southwest Areas Health and Welfare Fund v. Pathology Laboratories of Arkansas, P.A.)

EASTERBROOK, Circuit Judge.

The Baptist Medical Systems Hospitals of Little Rock, Arkansas, provide pathology services to their patients by contract with a group of eight pathologists, incorporated as Pathology Laboratories of Arkansas. A test of a blood or tissue specimen at one of the Hospitals leads to two charges: one from the Hospitals and one from Pathology Laboratories.
