Medicare Supplement (Medigap) plans in Utah

Medicare Supplement insurance — usually called Medigap — is private coverage that pairs with Original Medicare (Parts A and B). Instead of replacing Medicare, it fills the gaps: the deductibles, copayments and coinsurance you’d otherwise pay yourself. You then add a standalone Part D drug plan for prescriptions. The Utah Insurance Department regulates the policies; the benefits inside each plan letter are set federally.

How Medigap is different from Advantage

The plans Utahns actually buy

Plan G covers everything Original Medicare leaves behind except the Part B deductible ($283 in 2026). Plan N costs less in exchange for small office and emergency copays and no coverage of Part B excess charges. High-deductible Plan G has a much lower premium and a deductible you pay first. Plan F still exists for people who were eligible before 2020 but cannot be sold to anyone newer. Because benefits are standardized, we compare companies on price and on how fast they have raised it.

When you can buy one without health questions

• Your six-month open enrollment. It starts the month you are 65 or older and enrolled in Part B. During it, every plan a company sells is guaranteed available regardless of health. In Utah this is the window: there is no birthday rule, anniversary rule or annual Medigap window afterward.
• Guaranteed-issue events. Losing an Advantage plan or employer coverage through no fault of your own gives you a window (generally 63 days) to buy certain plans without underwriting.
• Under 65 on disability. Utah does not require insurers to offer Medigap before 65. A few companies do, usually at higher premiums; the Utah Insurance Department’s comparison tool lists them. Everyone gets a fresh open enrollment for every plan at 65.
• Outside those windows, Utah insurers can use medical underwriting. Switching later usually means answering health questions.

Compare the rate history, not just the first-year price

Because the benefits are standardized, the only real differences between Utah Medigap companies are what they charge and how steeply they raise it later. That second part is public: every carrier files its rate increases with the Utah Insurance Department, and a policy that looks cheap at 65 can be the expensive one by 75. We publish that filing history on our research site, Utah Medigap rate history, with each figure tied to the filing it came from. If your premium has already gone up and you want to know why, why Medigap premiums increase covers the three causes.

Who Medigap tends to suit

People who want maximum freedom to choose doctors and hospitals — Intermountain and the U in the same year, a specialist in Salt Lake from Vernal or Moab — predictable costs, and coverage that travels. That last point is why so many Utah snowbirds keep a supplement. The cost is a monthly premium that rises with age and with the carrier’s filings.
