Writing in The Street Melissa David says that a 6 year-long investigation of Caremark receiving overpayments for Texas Medicaid is about to result in indictments.  Caremark stock reacted poorly to the rumors.

Of course indictments and charges are nothing new in the PBM industry, and will only become more common when Medicare Part D is introduced next year.  Why?  Well the whole industry runs on secrets, and no-one really understands what’s going on, despite the attempt to develop "transparent PBMs".
