Costco Wholesale will pay $11.75 million to settle allegations that its pharmacies violated the Controlled Substances Act when they improperly filled prescriptions for controlled substances.

The settlement resolves allegations that Issaquah-based Costco pharmacies filled prescriptions that were incomplete, lacked valid DEA numbers or were for substances beyond various doctors’ scope of practice, according to a U.S. Attorney’s Office media release. Additionally, the settlement resolves allegations that Costco failed to keep and maintain accurate records for controlled substances at its pharmacies and centralized fill locations.

U.S. Attorneys Annette L. Hayes for the Western District of Washington, Michael C. Ormsby for the Eastern District of Washington, Eileen M. Decker for the Central District of California, Barbara L. McQuade for the Eastern District of Michigan and Phillip A. Talbert for the Eastern District of California announced the settlement on Thursday.

“Pharmacies across this country are on the leading edge of the battle against our prescription drug abuse crisis,” Hayes said. “A company such as Costco that distributes a significant volume of controlled substances has a responsibility to ensure it complies with regulations that help prevent opioids and other dangerous drugs from being misused or otherwise added to the illegal marketplace. I commend the Drug Enforcement Administration investigators for uncovering the violations at issue in this case, and working with Costco to ensure that systems are put in place to prevent controlled substances from ending up in the wrong hands.”

“Last year, over 50,000 Americans died as a result of drug overdoses, many of which were related to the misuse of prescription drugs. This settlement demonstrates the accountability and responsibility that go along with handling controlled prescription drugs,” said DEA Assistant Administrator Louis Milione. “DEA works every day to reinforce good corporate practices through outreach and education efforts and, when appropriate, with administrative and criminal action.”

Under the settlement, Costco acknowledges that between Jan. 1, 2012 and Dec. 31, 2015, certain Costco Pharmacies dispensed controlled substances inconsistent with their compliance obligations under the Controlled Substances Act (CSA) and its implementing regulations. The violations include: filling prescriptions from practitioners who did not have a valid DEA number; incorrectly recording the practitioner’s DEA number; filling prescriptions outside the scope of a practitioner’s DEA registration; filling prescriptions that did not contain all the required information; failing to maintain accurate dispensing records; and failing to maintain records for their central fill locations in Sacramento, Calif., and Everett.

“In light of the prescription pill and opioid overdose epidemic we are seeing across the country, compliance with regulations governing pharmacies is more important than ever,” McQuade said. “We applaud Costco for working with DEA and taking steps to tighten up its compliance to ensure that prescription pills do not end up on the street market.”

“These are not just administrative or paperwork violations – Costco’s failure to have proper controls in place in its pharmacies played a role in prescription drugs reaching the black market,” said Decker said. “Costco pharmacies in Southern California filled numerous prescriptions for drugs that should not have been sold to consumers because of its flawed system for validating DEA registration numbers.”

DEA Diversion Groups in Seattle, Los Angeles, Sacramento and Detroit investigated the case.
