Medicare has multiple components: Part A (hospital insurance), Part B (medical insurance), and Part D (prescription drugs), or a person can sign up for Medicare Part C, which integrate Parts A, B, and in certain scenarios D.
A person is eligible for premium-free Part A if he is at the age of 65 or older, and the person itself or his spouse worked and paid Medicare taxes for at least 10 years.
The person who has crossed his 60 years of age, is facing suddenly retirement in current days, and now requires health insurance for this adverse condition.
Generally, a person in this situation, who is looking for a new job, will decide to get enrollment into the Cobra insurance coverage without understanding the effects that this decision will buy when they are over age 65.
Medicare alarms people in these crises to not fluctuate between Medicare health insurance coverage and employer health insurance.
