Pennsylvania runs its ACA marketplace through HealthCare.gov rather than a state exchange, which means all plan shopping and subsidy applications happen at the federal level. The state expanded Medicaid under the ACA, so residents with incomes below 138% of the federal poverty level may qualify for Medicaid before marketplace plans are relevant.
For those shopping the marketplace, the insurer mix is more regional than in most states. Jefferson Health Plans covers the Philadelphia area only and Geisinger Health System's network follows its integrated hospital footprint in central and northeastern Pennsylvania. Where you live determines which plans you can buy and that answer comes before any premium comparison matters.
When we analyzed all 2026 plans available to a 40-year-old in Pennsylvania, the gap between the cheapest and most expensive Silver-tier HMO was $382 per month: $483 at Jefferson Health Plans and $865 at Geisinger Health System. That spread makes the rankings table below useful only after you've confirmed which insurers write policies in your ZIP code.
