Susie Tiffany of Beverly Hills suffers from a rare blood disorder and needs monthly infusions of blood components, which her insurance company ultimately declined to cover. She hoped the government\’s new prescription drug benefit would help her out because, despite her ZIP code, she\’s a low-income senior. But the possibilities, were baffling: an array of private insurance plans that covered different things, explanations on the Internet that included terms she never had to know before, additional complexities depending on a person\’s income and a confusing interplay of state and federal agencies. However, Tiffany was able to find assistance in her case from Jewish Family Service. A social worker helped get Tiffany\’s treatment covered by new state funds intended to help seniors with the transition to the new federal system.
