Independence Blue Cross plans to waive co-pays for 75 generic drugs that treat chronic conditions as a way of encouraging patients to take cheaper medicines. The Rx for Better Health program will be in effect from July 1 through December 31 for IBC and AmeriHealth of Pennsylvania subscribers. The program will not apply to those who have Medicare Part D, Medicare discount cards, or those who are members of the Federal Employees Health Benefits program and AmeriHealth of New Jersey or Delaware. The new initiative follows a broader program offered last year, which prompted a 15% increase in generic drug use.
