Medigap and Medicare Advantage in Indiana, Pennsylvania

INDIANA, Pa. — Every fall, people turning 65 in western Pennsylvania face the same fork in the road. Do you stick with Original Medicare and add a Medigap policy? Or do you go with Medicare Advantage? Both paths are legal, both are common, and both are explained on medicare.gov. But they work very differently — and once you understand the structure, the choice gets a lot clearer.

Here is a plain-language look at how the two paths are built, and what that means for people living in and around Indiana, Pennsylvania.

The Two Paths, Side by Side

Path 1: Original Medicare + Medigap (+ usually a Part D drug plan). Original Medicare is the federal program itself — Part A (hospital) and Part B (doctor and outpatient). You can see any doctor or hospital in the country that accepts Medicare, and most do. Original Medicare pays its share, and you're responsible for the rest. That "rest" can add up, which is why many people buy a Medigap policy (also called Medicare Supplement) from a private insurer. Medigap fills in deductibles and coinsurance. Because Original Medicare does not cover most prescriptions, people on this path usually add a stand-alone Part D drug plan too.

Path 2: Medicare Advantage (Part C). Medicare Advantage is offered by private insurance companies that contract with Medicare to provide your Part A and Part B benefits in one bundled plan. Most Advantage plans also include Part D drug coverage and extras like dental, vision, or hearing. In return, you generally use the plan's network of doctors and hospitals, and you follow the plan's rules for referrals and prior authorization.

You cannot combine the two. If you enroll in Medicare Advantage, you cannot also use a Medigap policy.

How the Money Flows

On the Original Medicare path, Medicare pays providers directly, and your Medigap plan picks up much of what's left. You'll have a monthly Part B premium, a Medigap premium, and usually a Part D premium.

On the Advantage path, Medicare pays the private plan a set amount each month to manage your care. You may still owe the Part B premium, plus whatever the plan charges. Your out-of-pocket costs come as copays and coinsurance as you use services, up to the plan's annual maximum.

Neither path is automatically cheaper. It depends on your health, your prescriptions, how often you travel, and which doctors you want to keep.

What's the Same on Both Paths in 2027

Some rules apply no matter which path you choose. These come straight from CMS:

• Part D out-of-pocket cap: Once your covered drug spending hits $2,100 in 2026, you pay $0 for the rest of the year on covered drugs.
• Part D deductible: No plan can charge more than $615 as a drug deductible in 2026.
• No more donut hole. As of 2025, Part D moved to three simpler phases.
• Medicare Prescription Payment Plan. You can ask to spread your yearly drug costs into monthly payments at no extra charge.
• IRMAA. Higher-income beneficiaries pay surcharges on Part B and Part D premiums. In 2026, IRMAA starts above $109,000 for a single filer.

Plan Availability in Indiana County

Indiana, Pennsylvania is in Indiana County, and — like everywhere in the U.S. — Medicare Advantage and Part D plan availability is set at the county level. That means two neighbors who live one county apart can see different lists of plans on medicare.gov. When you use the Plan Finder tool, be sure to enter your actual ZIP code so the results match where you live.

The number of Advantage and drug plans available in Indiana County changes each year as insurers enter, leave, or adjust their offerings. CMS publishes the full list every fall before the Annual Enrollment Period.

When You Can Switch Paths

• Annual Enrollment Period: October 15 – December 7. Anyone with Medicare can join, switch, or drop an Advantage or Part D plan. Changes take effect January 1.
• Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in an Advantage plan, you get one chance to switch to another Advantage plan or return to Original Medicare.

One important note about switching back: if you leave Advantage and try to buy Medigap later, insurers in most states can use medical underwriting. That means your health history can affect whether you qualify or what you pay. Your best protection from underwriting is usually during your one-time Medigap Open Enrollment Period when you first sign up for Part B at 65.
