Labor Department finalizes sweeping PBM disclosure rule
The Labor Department finalized a rule requiring pharmacy benefit managers (PBMs) to disclose compensation details to self-insured employers, aiming to lower drug costs by $22 billion over a decade. Effective July 2027, PBMs must share rebates, spread payments, and other data during contract negotiations and every six months. Non-compliance may result in financial penalties. The rule is supported by employers but opposed by PBMs, who argue it's excessive and duplicative.
