Here’s something that trips up a lot of people about Medigap: every Plan G is the same Plan G, no matter which company sells it to you. That’s federal law. So when we say “best Medigap providers,” we’re really talking about who charges the least for identical coverage, who treats you well when you call, and who’s going to be around to pay claims in 20 years.
Our team pulled quotes from seven major Medigap carriers across dozens of zip codes to put this list together. We also read through hundreds of customer reviews and checked financial stability ratings, because the cheapest plan from a shaky company isn’t actually a good deal.
One thing we learned while researching: rates for the exact same plan letter can vary by 30% or more between carriers in the same zip code. That’s real money — potentially hundreds of dollars a year — for coverage that is literally identical. So shopping around isn’t optional here. It’s the whole game.
David Chen helped his neighbor compare Plan G quotes last spring, and the spread between the cheapest and most expensive was $47/month. Same coverage, same zip code. That’s $564 a year for nothing.
Just a heads-up: Medigap premiums, Medicare deductibles, and out-of-pocket amounts get updated by CMS every year.

Quick answer: Humana is our top overall pick for broad availability and competitive pricing. Aetna typically offers the lowest premiums. Mutual of Omaha has the best customer service and a 12% couples discount. Since every Plan G is identical regardless of insurer, always compare quotes from at least three carriers.
