1. People are eligible for Medicare for different reasons. Some are eligible when they turn 65. People under 65 are eligible if they have received Social Security Disability Insurance (SSDI) or certain Railroad Retirement Board (RRB) disability benefits for at least 24 months. If they have amyotrophic lateral sclerosis (ALS), there’s no waiting period for Medicare. Some people with End Stage Renal Disease (ESRD) may be eligible for Medicare. It’s important to know the different ways that people qualify for Medicare so you can help current and former employees and their dependents anticipate their eligibility for Medicare so they can make timely and appropriate decisions about their enrollment. 2. Some people get Medicare Part A (Hospital Insurance) and Part B (Medical Insurance) automatically and some people need to sign up for them. People living in the United States and U.S. Territories (except Puerto Rico) who are already collecting Social Security—either disability or retirement—are automatically enrolled into Part A and Part B when they’re first eligible. These people will get a packet of information a few months before they turn 65 or receive their 25th month of Social Security Disability or Railroad Retirement Board (RRB) benefits. At that time, they can choose to keep or decline Part B, but can’t decline Part A unless they withdraw their original application for Social Security and pay back all Social Security cash benefits. People who aren’t yet collecting Social Security, or aren’t eligible for Social Security Retirement, aren’t automatically enrolled into Medicare. They must sign up by contacting Social Security. People living in Puerto Rico or foreign countries who already have Part A need to sign up for Part B by completing an Application for Enrollment in Part B (CMS-40B). This form is also available in Spanish (PDF). 3. Enrolling in Medicare can only happen at certain times. If someone is eligible for free Part A due to age, he or she can enroll in Part A any time after they’re first eligible for Medicare during the Initial Enrollment Period (IEP). An individual may be eligible for premium free Part A if they or their spouse paid Medicare taxes while working. If eligible for free Part A, coverage for Part A begins 6 months back from the date they apply, but no earlier than the first month of being eligible for Medicare. However, the law only allows for enrollment in Medicare Part B (Medical Insurance), and premium-Part A (Hospital Insurance), at limited times:
4. Determining whether a person qualifies for a Special Enrollment Period is the first important factor to consider when making a decision about Part B enrollment. It’s critical that employees and their dependents consider whether Part B is right for them when they’re first eligible for Medicare. Decisions about Part B enrollment for people with employer–based insurance first depend on whether a person has insurance based on current employment. Generally, if an individual (or their spouse) is still working and has employer-sponsored Group Health Plan coverage based on that employment, they can delay enrollment in Part B and can enroll later during a SEP. But, there are special rules that they need to know. For example, employer coverage for retirees or through COBRA doesn’t count as current employment, so these individuals don’t qualify for a SEP to enroll in Medicare later. A different set of rules apply if the person has Medicare based on disability or ESRD. 5. Knowing who pays first is the second important factor to consider when making a decision about Part B enrollment. When Medicare and another health insurance plan are responsible for paying the same medical claim, coordination of benefits rules determine how Medicare works with other health coverage. When someone is considering delaying or declining Part B, it’s important for the beneficiary to know:
Note that most retiree and small employer plans (employers with fewer than 20 employees) require enrollment in Part A and Part B. If the retiree plan you offer requires Medicare enrollment, please advise your employees planning to retire well in advance. If someone doesn’t sign up for Part B when first eligible, they may have to pay late enrollment penalties, in addition to the standard Part B premium amount, for as long as the person has Part B and they may face periods with little or no health coverage. |
