Medicare Supplement Insurance Plan B provides 100 percent coverage for each of the following four benefit areas:
Medicare Part A coinsurance and hospital costs
If you are admitted to a hospital for inpatient treatment, Medicare Part A helps cover your hospital costs once you reach your Medicare Part A deductible, which is $1,600 per benefit period in 2023.
For the first 60 days of your hospital stay, you aren’t required to pay any Part A coinsurance.
But beginning on day 61 of your stay, you’re required to make a Medicare Part A coinsurance payment of $400 per day through day 90. After your 90th day in the hospital, you must pay $800 per day for up to 60 more days. Beyond that, you are responsible for all costs.
These coinsurance costs can add up quickly. Medigap Plan B covers 100 percent of your Part A coinsurance costs.
Medicare Part B coinsurance or copayment
Medicare Part B helps cover costs for things like doctor’s appointments, medical devices and preventive care.
After you meet your Medicare Part B deductible (which is $226 per year in 2023), you are typically responsible for a coinsurance or copay of 20 percent of the Medicare-approved amount for covered services.
For example, if you suffer a foot injury and need to use a wheelchair, Part B will help cover 80 percent of the cost of your wheelchair (after you meet your Part B deductible). For illustration purposes, if it costs $800 to buy the wheelchair and Medicare Part B covers it as durable medical equipment (DME), your Part B coinsurance cost would be $160.
Medigap Plan B would fully cover your $160 Part B coinsurance.
First three pints of blood
Original Medicare does not cover the cost of the first three pints of blood you might need for a blood transfusion. Medicare Supplement Insurance Plan B covers 100 percent of the cost for your first three pints of blood.
Part A hospice care coinsurance or copayment
Medicare Part A requires a copayment for prescription drugs used during hospice care. You might also be charged a 5 percent coinsurance for inpatient respite care costs.
Medigap Plan B covers 100 percent of your Medicare Part A hospice care coinsurance or copayments.
Medicare Part A deductible
As mentioned above, the Medicare Part A deductible is $1,600 per benefit period in 2023.
The Medicare Part A deductible is not annual — you could potentially need to meet this deductible more than once in a given year.
Medigap Plan B covers 100 percent of the Medicare Part A deductible.
