Oregon's health insurance marketplace enrollment dropped 16.5% for 2026 — approximately 6,000 fewer people signed up compared to last year — as the expiration of enhanced ACA subsidies delivers sticker shock across the state. Premiums are climbing roughly 10% statewide, with some families seeing their costs effectively double. The driver: enhanced subsidies enacted during COVID in 2021 expired at the end of 2025, and Congress did not renew them.

The financial assistance cliff is steep. In 2025, approximately 80% of Oregon marketplace enrollees received premium subsidies. For 2026, that figure dropped to under 60%. Of the roughly 140,000 Oregonians who typically use the marketplace, thousands are now priced out. Marketplace director Chiqui Flowers put it bluntly: "Many current and potential Marketplace enrollees have experienced sticker shock."

This isn't just about enrollment numbers — it's about the composition of the risk pool. When healthier, younger enrollees leave the marketplace because premiums are unaffordable, the remaining pool skews sicker and more expensive, which drives premiums even higher the following year. Oregon is potentially entering that adverse selection spiral.

What this means for your practice: Embedded dental riders in marketplace plans are directly affected by this enrollment decline. Fewer insured marketplace patients means more uninsured or underinsured patients showing up for dental care. Practices should monitor their payer mix data for shifts — specifically, watch for increases in self-pay patients and decreases in marketplace-plan patients over the next two quarters. Budget for potentially higher uncompensated care and consider whether your financial policies (payment plans, sliding scales) are equipped for a less-insured patient population.
