If you’re 65 or older and haven’t signed up for Medicare Part B yet, now is your chance. The General Enrollment Period (GEP) runs from January 1 to March 31 each year. During this time, you can enroll in Medicare Part B if you missed your initial or special enrollment periods. However, there may be late penalties, so it’s important to understand your options.
Understanding Medicare Part A and Part B
Medicare has two main parts:
- Part A (Hospital Insurance): Usually free if you or your spouse paid Medicare taxes while working.
- Part B (Medical Insurance): Covers doctor visits, outpatient care, and preventive services. Most people pay a monthly premium for this coverage.
Who Needs to Enroll During the General Enrollment Period?
You should consider signing up during the General Enrollment Period (GEP) if:
- You were automatically enrolled in Medicare at 65 but declined Part B.
- You missed your Initial Enrollment Period (IEP) when you first became eligible.
- You didn’t qualify for a Special Enrollment Period (SEP) after losing employer health coverage.
- Your Part B coverage ended due to non-payment or voluntary withdrawal.
- You must pay a premium for Part A and didn’t sign up when first eligible.
How to Sign Up for Medicare Part B During GEP
The Centers for Medicare & Medicaid Services (CMS) manages Medicare, but the Social Security Administration (SSA) handles enrollment. Here’s how to apply:
- Complete Form CMS 40B – This is the official Medicare Part B enrollment form.
- Submit the form by fax, mail, or in person at your local Social Security office.
- Schedule an appointment for video, phone, or in-person assistance by calling 1-800-772-1213 (Monday-Friday, 8 AM – 7 PM).
Medicare Part D (Prescription Drug Coverage)
After enrolling in Part B, you may also want to sign up for Part D to get prescription drug coverage. This is done through a private insurance company, not Social Security.
When Does Part B Coverage Start?
Your Medicare Part B coverage begins the first day of the month after you enroll.
- Example: If you sign up in February, your Part B starts on March 1.
- You’ll receive a new Medicare card in the mail once your enrollment is processed.
How Much Does Medicare Part B Cost?
- Standard Monthly Premium: $185 in 2025
- Higher-Income Individuals: May pay more based on income
- If you’re receiving Social Security benefits, the premium is deducted automatically. Otherwise, you’ll get a bill.
Late Enrollment Penalty for Part B
If you delay signing up for Part B, you might have to pay a penalty:
- 10% increase in your premium for every 12 months you were eligible but didn’t enroll.
- This penalty lasts as long as you have Medicare.
Exceptions to the Late Enrollment Penalty
You won’t have to pay the penalty if:
- You qualify for a Medicare Savings Program due to limited income.
- You receive Social Security disability benefits and have turned 65.
Additionally, Part D (prescription drug coverage) also has a late enrollment penalty if you delay signing up.
If you missed enrolling in Medicare Part B during your initial eligibility period, the General Enrollment Period (GEP) from January 1 to March 31 is your opportunity to sign up. However, delaying can lead to penalties, so it’s best to enroll as soon as possible. If you need help, contact Social Security or visit Medicare.gov for more information.
