Preferred Medical Plan, the last of four insurers in Florida criticized by AIDS advocacy groups for the high cost of their HIV drugs, voluntarily agreed to cap the prices of the medication last week, according to the Miami Herald and Kaiser Health News. The company agreed to set the out-of-pocket cost limitation to $200 a month for four types of medication. According to the Herald, the Florida Department of Health and Human Services is still investigating federal civil rights complaints filed against Preferred and the other three companies, accusing the companies of discriminating against people with HIV by making their medication too expensive.
