Medicare Open Enrollment is January 1st-March 31st when you can leave your Medicare Advantage plan and return to Original Medicare–Medicare Part A and Part B. You then have the opportunity to purchase a Medicare Part D prescription drug plan and apply for a Medicare Supplement/Medigap policy. It is another opportunity to make sure you have the Medicare plan that best fits your needs. Most people are completely unaware. It is like the whole thing is a secret.
The Medicare & You Official Handbook says “it’s important to compare Medigap policies since the costs can vary between insurance companies for exactly the same coverage.” Don’t overpay for the exact same coverage. Make sure you thoroughly shop the market for the lowest prices from the most trusted sources.
