In this situation, if you aren't given an ABN before you get the item or service, and Medicare denies payment, then you may not have to pay for it. If you are given an ABN, and you sign it, you'll probably have to pay for the item or service if Medicare denies payment.

Benefit Period
The way that Original Medicare measures your use of hospital and skilled nursing facility (SNF) services. A benefit period begins the day you're admitted as an inpatient in a hospital or SNF. The benefit period ends when you haven't gotten any inpatient hospital care (or skilled care in a SNF) for 60 days in a row.

  • Whether a particular drug is covered

  • Whether you have met all the requirements for getting a requested drug

  • How much you’re required to pay for a drug

  • Whether to make an exception to a plan rule when you request it

The drug plan must give you a prompt decision (72 hours for standard requests, 24 hours for expedited requests).  If you disagree with the plan’s coverage determination, the next step is an appeal.

Coverage gap

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.

Medicare Medical Savings Account (MSA) Plan
MSA Plans combine a high deductible Medicare Advantage Plan and a bank account. The plan deposits money from Medicare into the account. You can use the money in this account to pay for your health care costs, but only Medicare-covered expenses count toward your deductible.
