CA probes CVS refill allegations

State pharmacy regulators have opened an investigation into reports that CVS Caremark Corp. refilled prescriptions and billed insurance companies without patients' consent. Virginia Herold, executive officer of the California Board of Pharmacy, said Tuesday that investigators were probing complaints about the refill practices of the country's largest drugstore chain after Walgreen Co. Herold said the complaints concerning "CVS and refills" were similar to allegations raised in four Los Angeles Times reports published in the last three months.
