Exception

A type of Medicare prescription drug coverage determination. A formulary exception is a drug plan's decision to cover a drug that's not on its drug list or to waive a coverage rule. A tiering exception is a drug plan's decision to charge a lower amount for a drug that's on its non-preferred drug tier. You or your prescriber must request an exception, and your doctor or other prescriber must provide a supporting statement explaining the medical reason for the exception.

Excess charge

If you have Original Medicare, and the amount a doctor or other health care provider is legally permitted to charge is higher than the Medicare-approved amount, the difference is called the excess charge.

Extra Help

A Medicare program to help people with limited income and resources pay Medicare prescription drug program costs, like premiums, deductibles, and coinsurance.
