Suspected "fraudulent" actions by middlemen in the prescription drug supply chain for more than 3 million poor and disabled Ohio residents are being targeted Wednesday by a legislative watchdog panel. The Joint Medicaid Oversight Commission is dedicating an entire meeting to how pharmacy benefits managers are using loopholes to dodge state restrictions on such practices as "clawbacks," as The Dispatch revealed in July. The central issue: Even months after a drug transaction is supposedly finalized, the PBM can "claw back" additional revenue from the pharmacy if the PBM determines it didn't receive enough money initially.
