Medicare enrollees, who have watched their out-of-pocket spending on prescription drugs climb in recent years, might be in for a break.

Federal officials are exploring how beneficiaries could get a share of certain behind-the-scenes fees and discounts negotiated by insurers and pharmacy benefit managers, or PBMs, who together administer Medicare’s Part D drug program. Supporters say this could help enrollees by reducing the price tag of their prescription drugs and slow their approach to the coverage gap in the Part D program.

The Centers for Medicare & Medicaid Services (CMS) could disclose the fees to the public and apply them to what enrollees pay for their drugs. However, there’s no guarantee that such an approach would be included in a proposed rule change that could land any day, according to several experts familiar with the discussions.
