A health care organization proposed in the (fall 1995) Republican House Medicare reform proposal. A PSN is operated by providers and is funded in part by the capital contributions of its members. It requires all members to provide health care to Medicare beneficiaries, and it receives the compensation on behalf of the members and distributes it among them. A PSN is given some antitrust protection under the bill with regard to establishment of fee schedules and the conduct of the network. A PSN is designed to operate like an HMO, offering HMO services and assuming risk, but is to be exempt from being regulated as an insurance company.
