Do I Need Medicare If I Have Health Insurance? 
If you have current health insurance provided by your employer , and it is a comprehensive plan covering office visits , prescriptions and major medical , you should continue on that plan , assuming that rates are low or the employer is paying the premium . If you are age 65 or older , and are covered under a group plan at work , you will still be eligible for an Open Enrollment for a Medicare Supplement plan when you lose your existing coverage . It will be best to utilize an experienced broker and/or a reputable national website when you are in that situation . There will be many plan options available .
