Cancellation rates are highest among ages 55–64, followed by younger adults in their late 20s and early 30s, which could push up premiums for those who remain enrolled.

Erie County is anticipated to see a substantial but smaller premium increase of about 80% or roughly $129 per month.

As of December 11, several counties, including Monroe, Carbon, Lebanon, York, and Beaver, reported at least 10% of their enrollees canceled.

State estimates indicate premiums could roughly double in 2026 without subsidies, unless Congress acts to extend them, due to the expiration of federal tax credits.

Thousands of Pennie enrollees have canceled during open enrollment, with total cancellations surpassing 45,000 across Pennsylvania.

The largest average premium increases by county are projected in Juniata ($367), Fulton ($336), Schuylkill ($347), Lehigh ($330), and Northampton ($317).

Premium increases will vary by enrollees’ age, income, and location; county-by-county estimates show the biggest percentage hikes in Juniata, Fulton, Northumberland, Mifflin, and Snyder counties.

If federal Obamacare subsidies expire, the average Pennie premium could jump by as much as $367 per month, with county-level variation and up to 485% increases in Juniata County.
