Medicare is a federally-sponsored program designed to provide individuals age 65 and older, and those with qualifying disabilities, with health care insurance. The entire program is split into several parts. Medicare Part B is medical insurance that helps participants pay for the costs of doctor bills and outpatient medical care. Part B also covers some of the medical services that Medicare Part A (hospital insurance) doesn't cover.
Enrolling in Medicare Part B is not mandatory, but there are three distinct ways of enrolling. Anyone eligible for Social Security or Railroad Retirement benefits are automatically enrolled in Part B starting on the first day of the month in which they turn age 65. The three ways of manually enrolling in Medicare Part B include:
The initial enrollment period for Medicare Part B starts three months before the month in which an individual turns age 65 and ends six months later, which is three months after turning age 65. Please note that although some citizens may not be eligible for full Social Security benefits until after the age of 65, this does not affect Part B eligibility.
If an individual does not sign up for Part B when they first become eligible, they can take advantage of the general enrollment period each year. General enrollment runs from January 1st through March 31st of each calendar year; coverage begins on July 1st.
Anyone delaying enrolling in Medicare Part B may have to pay an additional percentage of the current premium. This is explained in more detail later on, when premiums and deductibles are outlined.
The special enrollment period is for those individuals that were eligible for Medicare, but decided to wait to enroll in Part B because they had health care coverage through their employer or a spouse's employer.
Under these circumstances, it's possible to apply for Part B while still covered by a healthcare insurance plan. Individuals can also apply during the eight months following the month an employer's health plan coverage ends, or when employment ends, whichever comes first.
Anyone signing up for Medicare Part B during their special enrollment period does not have to pay an additional amount towards their premium. However, individuals that sign up during general enrollment may have to pay an additional premium.
Medicare Part B is designed to pick up where Medicare Part A leaves off. That means Part B will cover certain medically necessary services such as non-routine doctor visits, outpatient surgery and supplies, diagnostic tests, and items that are termed durable medical equipment. This includes wheelchairs, walkers, oxygen equipment, and in-home hospital beds.
Under certain conditions, Medicare Part B can also cover second and even third opinions for surgery that isn't considered a medical emergency. Part B will also cover the costs of laboratory services such as blood tests, and some screening tests in addition to urinalysis.
If the patient requires home health care services, the cost of these expenses are also covered by Medicare Part B. This includes reasonable and necessary skilled nursing care, health aid providers, physical therapy, and durable medical equipment such as wheelchairs and walkers.
Starting back on January 1, 2005, the Medicare program expanded the preventative care services offered under Part B insurance to include:
Finally, the preventative services offered under Medicare Part B also includes a "Welcome to Medicare" physical examination.
In 2018, the Medicare Part B monthly premium was $134.00. In 2019, premiums will increase to $135.50. Taxpayers with a status of married, filing jointly will pay higher premiums if their modified adjusted gross income is in excess of $170,000. The higher premium limit is $85,000 for all other taxpayers as demonstrated in the table below. Note there is a two year lag for this premium limit (2017 income applies to 2019 premiums).
|Individual Tax Returns||Married Filing Separately||Joint Tax Returns||Premium|
|$85,000 or less||$85,000 or less||$170,000 or less||$135.50|
|$85,001 to $107,000||$170,001 to $214,000||$189.60|
|$107,001 to $133,500||$214,001 to $267,000||$270.90|
|$133,501 to $160,000||$267,001 to $320,000||$352.20|
|$160,001 to $500,000||$85,001 to $415,000||$320,001 to $750,000||$433.40|
|$500,001 or more||$415,001 or more||$750,001 or more||$460.50|
Note: The above table shows the 2019 premiums, which are based on the participant's 2017 federal income tax return.
Individuals that delayed enrollment in Medicare Part B past the Initial Enrollment Period, will pay premiums that are up to 10% higher for each 12 month period delayed. These increases are applied to the monthly premium for life.
The deductible for Part B is $183.00 per year in 2018, and will be indexed to the average increase in costs associated with Part B services. In 2019, the Medicare Part B deductible increases to $185.00 per year.
After the deductible is satisfied, there is a 20% coinsurance payment due on all Part B covered services. Our article on Medicare Supplemental Insurance provides information that can help patients control deductible and coinsurance payments within the Medicare program.
