Each year, the Centers for Medicare & Medicaid Services (CMS) set the following year’s Part B premium. In 2017, the Part B base premium will be $134. But you will not necessarily pay this increased amount.

If you collect Social Security benefits and your Medicare Part B premium is deducted from those benefits each month (this is the case for the majority of people with Medicare), you may be protected under the hold harmless provision. The hold harmless provision protects Social Security recipients from paying higher Part B premium costs so long as:

  1. You were entitled to Social Security benefits for November and December of the previous year (2016);
  2. The Medicare Part B premium will be or was deducted from your Social Security benefits in November 2016 through January 2017;
  3. You don’t already pay higher Part B premiums because of Income-Related Monthly Adjustment Amount (IRMAA) eligibility; and
  4. You do not receive a Cost of Living Adjustment (COLA) large enough to cover the increased premium. COLA is additional income given to Social Security recipients to protect against inflation decreasing the benefit’s purchasing power. The COLA in 2017 will be 0.3% of your Social Security benefit.

Because the COLA for 2017 is not large enough to cover the full amount of the increased premium, if you are held harmless, your premium will not increase up to $134. Instead, your premium increase will be the same as the increase in your Social Security benefit. The average Part B premium for individuals protected by the hold harmless provision is $109.

The hold harmless provision does NOT protect you if:

  1. You are new to Medicare. Hold harmless does not apply to you because you have not been enrolled in Medicare Part B long enough to qualify.
  2. You are subject to IRMAA.
  3. You are enrolled in a Medicare Savings Program (MSP). However, the MSP should continue paying for your full Part B premium.
  4. You were enrolled in a Medicare Savings Program in 2016 but lost the program because your income increased or you failed to recertify.

Note: If you qualify for the hold harmless provision but pay a Part B late enrollment penalty, the penalty will not be waived, and it may increase. This is because the penalty will be calculated based on the new, higher premium—even if you are not paying that higher amount.
