It is smart to compare Medicare supplement plans at least once a year to see if you can save money by switching plans or insurance companies. Why? Here are the three things we see happening with Medicare supplement rates: rates change - amount and frequency; household discounts change - some are offering up to a 12% household discount; and, some carriers are pricing Plan G much more favorably than Plan F. While many can see savings of a couple of hundred dollars per year, we recently came across a customer paying almost double what she could pay by switching to another insurance company for her Medicare Supplement Plan N.
