Medicare Part B

Medicare has four parts, or programs, that provide coverage for different health-related services. Understanding how Medicare works may help you choose the Medicare options that best fit your needs.

Medicare Part B, also known as the Medical Insurance program, helps pay for medically necessary services, such as:

  • Doctors’ services
  • Outpatient care
  • Some home health services, such as physical and occupational therapy
  • Some preventive services

Who Is Eligible for Medicare Part B?

If you are 65 or older (and get benefits from Social Security or the Railroad Retirement Board), you are automatically eligible for Medicare Part B. Your Medicare Part B coverage starts on the first day of the month you turn 65. You also should receive your Medicare card in the mail three months before your 65th birthday.

If you are under 65, you are eligible to receive Part B benefits under the following circumstances:

  • You have been diagnosed with amyotrophic lateral sclerosis (Lou Gehrig’s disease). If you have ALS, you get Part A the month your disability benefits begin.

Do I Have to Pay a Premium for Medicare Part B?

You will need to pay a monthly premium for Part B that can be deducted from your monthly social security check.

Most people pay a standard monthly premium for Part B, which is $96.40. For 2010, if you had a high income in 2008 (over $85,000 per individual; $170,000 per couple), you will have to pay a higher monthly premium for Part B, ranging from $154.70 to $353.60.

Medicare Part B is a voluntary program and you can opt out of it and not pay the monthly premium. If you do not want Medicare Part B, follow the instructions that come with your Medicare card. You will need to send the card back. If you want to stay in Medicare Part B, just keep the card and you will have Part B premiums deducted from your social security check.

If your income is limited and you cannot afford the monthly premium Part B, your state may have a program to help.

What does Medicare Part B Cover and What Do I Have to Pay?

Medicare Part B has an annual deductible, which in 2010 is $155.00.

You must pay all costs until you meet this yearly deductible before Medicare starts to pay its share. After you meet your deductible, you may be responsible for a coinsurance of 20% of the Medicare-approved amount for the service.

In general, Medicare Part B covers two types of services:

  • Medical services – healthcare services (and related supplies) that you may need to diagnose and treat a medical condition. Medicare will only pay for services that they define as being medically necessary.
  • Preventive services – healthcare services to prevent illness (such as a flu shot) or help detect an illness in an early stage so it can be managed before getting worse (such as screening for colon cancer).

Medical Services
Some examples of covered medical services include:

  • Ambulance Services – only if necessary and only to the nearest appropriate medical facility
  • Clinical Laboratory Services – certain blood tests, urine tests, and some screening tests

  • Doctor Services – care and prevention services that you get from your doctors in their office and some services provided in the hospital

  • Prescription Drugs – generally limited to injections you get in your doctor’s office, certain oral cancer drugs, and some drugs used with equipment such as a nebulizer or infusion pump

Should I Enroll in a Medigap Plan?

While Medicare Part B will most likely pay for most of your outpatient medical expenses, you still may have some out-of-pocket costs. So, you may want to consider a Medigap plan to help pay these out-of-pocket costs such as the annual Part B deductible, coinsurance charges and copayments. If you enroll in a Medicare Advantage plan, some of these costs may also be covered.
