California Medicare Supplement - Medicare Resource Center

A Medicare supplement is a type of insurance - also known as Medigap insurance - that covers some of the healthcare costs that the original Medicare leaves behind. It can help people fill their coverage gaps. Unlike regular Medicare, it does not require them to pay a huge amount of out-of-pocket expenses.

Since the federal government has standardized the benefits of Medicare supplement plans, they are now uniform across all insurance companies in the country. Before people start looking for a new plan, it is important to familiarize themselves with the pricing methods of the carriers.

Your carrier's pricing method can affect the monthly premium rates of your Medicare supplement plan. It is also important to note that if you have a spouse who needs coverage, then they must purchase a separate policy.
