Medicare at 65: The standard may be able to access age

The month you turn 65, you become may be able to access for Medicare Part A (hospital insurance) if you or your spouse has worked and paid Medicare taxes for at least 10 years. You do not have to stop working. You do not have to retire. Your may be able to access depends on your work history, not your current job status.

Your Initial Enrollment Period runs for seven months: three months before the month you turn 65, the month you turn 65, and three months after. During this window, you can sign up for Part A and Part B (medical insurance) without waiting or paying a penalty. If you miss this window and do not have other health coverage, you will pay a higher premium for Part B for as long as you have Medicare.

You can sign up online at Medicare.gov, by phone at 1-800-MEDICARE, or in person at your local Social Security office. You will need your Social Security number and information about any current health coverage.

Early may be able to access through disability: SSDI and the 24-month rule

If you have been receiving SSDI for 24 months, you become may be able to access for Medicare automatically. This applies no matter your age. The 24 months are counted from the month your disability benefits began, not from the month you applied.

Social Security will send you a notice when you are about to reach 24 months on SSDI. Your Medicare coverage will start the first day of the month you reach that milestone. You do not have to do anything — the enrollment happens automatically. Part A is free for most people who may have access to this way because they have already paid Medicare taxes through their work history.

If you are unsure whether you are on SSDI or Supplemental Security Income (SSI), you can check your Social Security account online at ssa.gov or call Social Security at 1-800-772-1213. The two programs have different rules, and only SSDI leads to automatic Medicare enrollment.

Special may be able to access: ESRD and ALS

People with end-stage renal disease (ESRD) who need dialysis or a kidney transplant may be may be able to access for Medicare before age 65. The same is true for people with amyotrophic lateral sclerosis (ALS), also called Lou Gehrig's disease. These conditions have their own enrollment pathways because of the high cost of treatment.

If you have ESRD, your may be able to access date depends on when you start dialysis or receive a transplant. If you have ALS, you become may be able to access for Medicare the month your SSDI benefits begin — you do not have to wait 24 months like other disability beneficiaries.

To find out your exact start date, contact Social Security at 1-800-772-1213 or visit your local Social Security office. Bring documentation of your diagnosis and any medical records related to your treatment. Social Security will confirm your may be able to access and tell you when to expect your Medicare card.

What happens if you miss your Initial Enrollment Period

If you do not sign up for Part B during your seven-month Initial Enrollment Period and you do not have other may have access to health coverage, you will pay a permanent penalty. The penalty is 10 percent of the standard Part B premium for each full year you were may be able to access but not enrolled. This penalty stays with you for life, even if you sign up later.

There are exceptions. If you were covered by an employer health plan while you were still working, you have an eight-month Special Enrollment Period after your coverage ends or you leave your job. During this window, you can sign up for Part B without penalty. You will need to show proof of your employer coverage — usually a letter from your employer's benefits department or your insurance card.

If you missed your important date and did not have employer coverage, you can still sign up for Medicare, but the penalty will explore. You can enroll during the General Enrollment Period (January 1 to March 31 each year), and coverage will start July 1. Talk to a Social Security representative about your specific situation — some people may have access to for exceptions.

Still working at 65: Your enrollment options

You can keep working past 65 and still be may be able to access for Medicare. If your employer has 20 or more employees and offers health insurance, you can delay Part B enrollment without penalty. You must still enroll in Part A, but you can wait on Part B as long as you have employer coverage.

When you leave your job or lose your employer coverage, you have eight months to sign up for Part B without penalty. This is called the Special Enrollment Period. You will need proof that you had employer coverage — your employer's benefits office can provide a letter stating your coverage dates and that you were enrolled in a group health plan.

If your employer has fewer than 20 employees, different rules explore. Medicare becomes your primary payer, and your employer coverage is secondary. In this case, you should enroll in both Part A and Part B when you turn 65 to avoid confusion about which insurance pays first.
