➤ How many people in Pennsylvania have Medicare Advantage?
Roughly 1.6 million Pennsylvanians are enrolled in a Medicare Advantage plan, out of about 2.8 million Medicare beneficiaries statewide. That is close to 58 percent, slightly above the national average, and it makes Pennsylvania the fifth largest Medicare Advantage market in the country by enrollment.
➤ When do 2027 Pennsylvania plan details become available?
October 1, 2026. That is when premiums, provider networks, drug formularies, supplemental benefit amounts and out-of-pocket maximums publish for every plan in every Pennsylvania county. Enrollment opens two weeks later on October 15 and runs through December 7, for coverage beginning January 1, 2027.
➤ Does it matter where in Pennsylvania I live?
A great deal. Medicare Advantage plans are sold county by county, and Pennsylvania has unusually distinct regional markets. Western Pennsylvania is shaped by integrated health systems that own both hospitals and insurance plans. Southeastern Pennsylvania around Philadelphia is a separate, highly competitive market. Central and northeastern counties generally have fewer carriers.
The practical consequence is that plan recommendations you read nationally, or advice from a friend in another part of the state, may not apply to you at all. Compare what is actually offered in your county.
➤ What happens if my plan is discontinued for 2027?
Your carrier must send a non-renewal notice by early October. Losing your plan triggers a Special Enrollment Period, so you are not limited to the standard window, and you have until the end of February 2027 to choose a new Medicare Advantage plan.
If you do nothing, you will generally be returned to Original Medicare on January 1, without drug coverage unless you enroll in a standalone Part D plan. That is the outcome to avoid, because going without creditable drug coverage can create a permanent late enrollment penalty.
➤ Will Pennsylvania plans still offer dental, vision and hearing in 2027?
Many plans may continue to include supplemental benefits like dental, vision, hearing and over-the-counter allowances, though not all plans offer all benefits and the amounts vary considerably by plan and by county. Because plans are being paid more in 2027 than in 2026, there is less pressure to cut these benefits than there was in the previous two years, but nothing is confirmed until plan details publish on October 1, 2026.
➤ Can I switch back to Original Medicare later?
Yes. You can return to Original Medicare during the Annual Enrollment Period each fall, or during Medicare Advantage Open Enrollment between January 1 and March 31 if you are currently in an Advantage plan.
One thing to understand before you do: Pennsylvania does not guarantee your right to buy a Medicare Supplement policy after your initial six month open enrollment window has passed, outside of specific guaranteed issue situations. Leaving Medicare Advantage is straightforward. Getting a supplement to pair with Original Medicare afterwards may require medical underwriting, and you can be declined.
