What happens if I decline Medicare coverage during the initial enrollment period?
If you decline Medicare during the initial enrollment period, your premiums for Part B can be increased by 10% for every 12 month period that you did not have Part B. The exception is if you are receiving employment-based health coverage, through an employer, association or union. The employer, however, must cover a minimum of 100 employees. In this case, you would be eligible for a special enrollment period.
