Medigap or Medicare Advantage in Indiana?

The right choice depends on your doctors, where you spend the year, and how you want to pay for care. Here is how the trade-off plays out in Indiana.

Medicare Supplement (Medigap)

Works with Original Medicare

  • See any doctor or hospital that accepts Medicare, anywhere in the country
  • Higher monthly premium, very predictable costs after that
  • No referrals or network rules
  • Every birthday you can move the same plan to a lower-priced company

Compare Medigap plans G, N, K and L

Medicare Advantage

A private plan that replaces Original Medicare

  • Lower or $0 premium in many Indiana counties, often with dental and vision
  • Networks, prior approvals and a yearly out-of-pocket limit
  • Northwest Indiana residents should check Chicago-area doctors are in network
  • Change plans each fall, October 15 to December 7

Medicare Advantage vs Medigap, in depth

How the Indiana birthday rule works

Indiana’s rule is about shopping companies for the same plan. It protects you when your current company raises rates.

  • Your windowFrom 31 days before your birthday to 31 days after, every year.
  • What you can buyThe same plan letter you have now, including its variations (for example Plan G to Plan G), from any company selling that plan in Indiana.
  • Who qualifiesPeople 65 and older who already have a Medigap plan in force.
  • Timing tipThe new policy starts the first of the month after you apply. Keep your old policy until the new one is in effect.
  • Other doorsYour 6-month window at 65 and the federal guaranteed-issue rights still apply. If your Advantage plan is leaving.

On Medicare before 65 in Indiana

  • Which plansAny company that sells a Medigap plan to people 65 and older must make the same plan available to you.
  • Your windowA 6-month guaranteed-issue window starting the first day of the month your Medicare begins.
  • PricePrices before 65 can be higher, so we compare which companies price this group fairly.
  • At 65You get a new 6-month open enrollment at 65 with every plan and company open to you.

Price is today. Rate history is the next ten years.

Every Plan G pays the same benefits, so companies compete on price. But many Medigap policies are priced by your current age, so the premium rises as you get older, on top of any rate increases the company files with Indiana regulators. Two companies can quote nearly the same price today and be far apart in five years.

We show past rate increasesWhen we quote, you see how each company has raised rates, not just who is cheapest this month.

Ask Indiana’s regulatorsThe Indiana Department of Insurance oversees Medigap companies and handles complaints about a company.

Discounts that lastAsk about household discounts and how long they apply. Some shrink after the first years.

Questions Indiana clients ask

How does the Indiana Medigap birthday rule work?

Each year, from 31 days before your birthday to 31 days after, you can switch to the same Medigap plan letter with any company selling it in Indiana, with no health questions. The rule began January 1, 2026, and the window was widened on March 15, 2026.

Can I switch from Plan G to Plan N on my birthday in Indiana?

Not under the birthday rule. It lets you keep the same plan letter and change companies. Moving to a different plan still usually means health questions unless another guaranteed-issue right applies.

Can I get a Medigap plan in Indiana if I am under 65?

Yes. Since 2025, companies must make the plans they sell to people 65 and older available to people on Medicare because of a disability or ESRD, during a 6-month window when Medicare begins.

When does my new Indiana Medigap policy start?

The first day of the month after you apply. Keep your current policy until the new one is in effect so you are never without coverage.

Does it cost anything to work with you?

No. Insurance carriers pay agents a commission, and your premium is the same whether you enroll through us or directly with the company.
