The United States Court of Appeals for the Seventh Circuit recently reversed the conviction of Mark Sorensen, the owner of SyMed Inc., a Medicare-registered distributor of durable medical equipment (DME), for alleged violations of the federal Anti-Kickback Statute (“AKS”).  This case, described by the court as one that “tests some of the outer boundaries” of the AKS, highlights the distinction between illegal kickbacks and lawful advertising payments under the AKS.
