As far as I know, Medicare does not require you to sign up. However, your group health insurance will almost certainly require you to do so.
Your job insurance is the primary. Usually medicare/disability comes first then others supplement.
Where you covered under an Employer Group or Individual Plan? If Employer Group - they would be eligible for COBRA - If Individual - then just tell the Insurance Company to take you off.
The best way to tell is to call your work-based health plan and ask them directly.
As long as the only reason you are covered by Medicare is because of a disability and you haven't reached the minimum age Medicare requires to become eligible naturally, then the number of members in the group health plan will determine who is primary or secondary. Group plans with fewer than 100 members are considered to be "small" businesses and Medicare would be primary. Conversely, "large" businesses (more than 100 members) will be primary over Medicare. It doesn't matter whether the group plan is provided by you or your spouse. At the time you reach Medicare's required age to naturally become eligible with them, your case will be reviewed. At that point, the group size doesn't matter. If you have other coverage provided by you or your spouse, it will always be primary over Medicare. Medicare won't become primary until both you and your spouse have retired and are no longer covered by a group health plan. Medicare supplement plans are always secondary to Medicare, but then those aren't group health plans.
In general, yes. Medicare can be secondary insurance for a person otherwise entitled to it who continues to work beyond the age of 65 and participates in a health insurance plan offered by or sponsored by the employer. Additionally Medicare can be a secondary payer for disabled people who have their own coverage through their own employer's large group health plan (usually 100 or more employees), or large group health coverage that they have through a family member.
You have a choice to stay in your employer's plan or join Medicare. When you do stop working and lose your group health plan, make sure you enroll in Medicare within 8 months. You could also enroll in Medicare Part A (hospital coverage), and postpone enrolling in Part B (physician coverage) until you are done with your group health plan. Part A does not cost you a monthly premium. You would be over-insured, but the Part A benefit is available to you at age 65, whether you have other coverage or not.
The answer to this question depends on what kind of secondary insurance you have - is it a group health plan? Is it a supplement? If Medicare is primary, there are still deductibles, copays, coinsurance that would need to be satisfied by your secondary insurance. Based on your question, I'm assuming that you have a group health plan with a copayment as your secondary insurance. If so, then yes, you would pay your copayment but it would not exceed the part B deductible.
Private health insurance companies generally avoid the elderly. If an elderly person currently does not have medical insurance, their best bet is to find a job that will grant group insurance regardless of their age, or to apply for Medicare.
Indiana has several different health insurance options to suit many different needs. There are family and individual, dental, group, student, short-term, and medicare plan options available.
Medicare is primary if your group is under 20 lives. 20 lives or more and medicare is secondary to your employer paid group plan.
In 1965, Congress created Medicare under Title XVIII of the Social Security Act to provide health insurance to people age 65 and older. However, for those individuals 65 and over who are still working and covered under an employer sponsored group health plan, the group plan generally pays first *if* the employer has more than 20 employees.
