A recent Office of Inspector General study of how much states pay R.Ph.s for Medicaid drugs outrages some industry leaders. "I'm disgusted," said John Coster, VP of the National Association of Chain Drug Stores. "Instead of a real analysis of the program, they restate the obvious, which is that states pay [for Medicaid drugs] differently. With all due respect, it reflects a trend of OIG reports that lack methodological rigor."
