Retiree Drug Subsidy

The Retiree Drug Subsidy Program is a program offered by the Centers for Medicare & Medicaid Services (CMS) to reimburse health plan sponsors (municipalities, unions and private employers) for a portion of their eligible expenses for retiree prescription drug benefits. This enables Plan Sponsors to continue providing drug coverage to their Medicare-eligible retirees at a lower cost.

Benefits of the RDS Program for participating Plan Sponsors include:[http://rds.cms.hhs.gov/user_guide/userguide/ug_003.htm#t029 RDS User Guide]{{dead link|date=June 2025|bot=medic}}{{cbignore|bot=medic}}, Centers for Medicare and Medicaid Services, Version 17, May 11, 2013

• A Federal subsidy equal to 28-percent Qualifying Covered Retiree's costs for prescription drugs otherwise covered by Medicare Part D that are attributable to such drug costs between the applicable Cost Threshold and Cost Limit
• Incurred costs (including dispensing fees) that the Health Plan Sponsor pays, and that the retiree pays, are eligible for subsidy. Rebates received are subtracted from the amount eligible for subsidy.
• Program flexibility that supports the Health Plan Sponsor's current prescription drug plan structure
• Extensive educational materials and support

To qualify for the subsidy, a Health Plan Sponsor must show that its coverage is "actuarially equivalent" to, or at least as generous as, the defined standard Medicare Part D coverage.
