Catastrophic Health Reimbursement Account (CatHRA)

Retirees with an extremely high usage of prescription drugs may reach the Medicare Part D catastrophic coverage limit. To help these retirees, USG has created a special program called the Catastrophic Health Reimbursement Account (HRA).

How does the Catastrophic HRA work?

In 2016 and 2017, USG will reimburse retirees for the full amount of any Medicare Part D copayment and coinsurance expenses incurred in the catastrophic phase of coverage for prescription drugs covered under Medicare Part D.

What should I do if I reach the catastrophic coverage limit?

If you or your covered spouse reaches the catastrophic coverage limit, your Medicare Part D insurance company will send you a Medicare Part D Monthly Prescription Drug Summary statement showing you have reached the catastrophic coverage limit.


  • Save the Medicare Part D Monthly Prescription Drug Summary statement
  • Contact your Aon Retiree Health Exchange Benefits Advisor immediately to access Catastrophic HRA support
