Medicare Part B Explained

Medicare Part B generally covers Medical Expenses

Explaining Medicare Part B starts with knowing what it covers. Medicare Part B covers things like: doctors visits, tests, diagnostic procedures, and x-rays. Part B medications area also covered (prescription medication administered in a doctors office).  Additionally, durable medical equipment  falls under Medicare Part B.  Note: this is not an exhaustive list of items covered.

It’s also important to know what Medicare Part A and B doesn’t cover.

The following are not covered: most dental work, prescriptions picked up at your local pharmacy, Vision services (except Cataract removal and treatment of Glaucoma), Long-Term Care services, vitamins, over the counter items, and elective or non-medical services.  Note: this is not an exhaustive list of items not-covered.

When do you enroll? 

You will generally want to enroll in Medicare Part B during your initial enrollment period.  The initial enrollment period is a 7 month window that begins 3 months before you’re first eligible for Medicare (Either the month you turn 65 or the 25th month of disability).

Example:  Mary turns 65 on July 15th, 2014 she is eligible to enroll in Medicare Parts A,B,C, and D from April 2014 till October 2014.


It’s critical to understand when your coverage will start!  If you sign up for Medicare Part A (Hospital Insurance) and/or Medicare Part B (Medical Insurance) during the first 3 months of your Initial Enrollment Period, your coverage starts the first day of your birthday month, unless your birthday is on the first day of the month.

Example 1:

If Mary’s birthday was September 2nd and she signed up in June her Coverage would start on September 1st.

Example 2:

If Mary’s birthday was September 1st and she signed up in June her Coverage would start on August 1st.

How much does Part B cost?

The cost for Medicare Part B depends on your income level.

For individuals NOT on public assistance (Medi-Cal or Medicaid)  and earning less than $103,000 the standard premiums for 2024 is  $174.70 a month.

Low income individual may qualify for Medicaid, and Medicaid would pay for your monthly Medicare Part B premiums.

If your income exceeds $103,000 individually or $206,000 jointly you’ll have to pay an additional  amount called the income-related monthly adjustment amount.  The amount is determined by your MAGI or Modified Adjusted Gross income from 2 years ago.

How do I enroll in Medicare PART A and/or PART B?

If you are currently receiving Social Security Income or Railroad Retirement Income you will likely not need to do anything and will be automatically enrolled when you turn 65 or are in your 25th month of disability.  However, if you are not receiving either of the previously mentioned funds you will need to contact Social Security via phone, in-person, or online.  To enroll online visit the Social Security website


Not enrolling in Medicare when you are first eligible will likely result in a permanent penalty and a serious lapse in coverage.  If you have already missed your initial enrollment period we can help you minimize the penalty and get temporary health coverage.
