Really, that's basically what Greg Van Pelt told them. He didn't even mention the problems until page four of his prepared remarks.
The bulk of Van Pelt's written testimony focuses on Oregon's reforms to its version of Medicaid, the Oregon Health Plan, and the benefits of the Affordable Care Act: "Everyone from the homeless woman sleeping on the streets of Portland to the rancher in Ontario to the freelance designer with a preexisting condition in Astoria can get comprehensive health care coverage that includes preventive care and health screenings, prescription coverage, and mental health care ... The reality of our former insurance system was that people got underwritten out and were forced into expensive high-risk plans."
Of course, of the 300,000 claimed enrollees, 125,000 were directly migrated into Medicaid using their "fast-track" system that completely bypassed Cover Oregon, while over 120,000 more were added to Medicaid after the Exchange forwarded their enrollment data to the state for processing. In other words, over 245,000 receive taxpayer-funded, "free" health insurance through Medicaid; they don't even pay a monthly premium.
Only 55,000 were actually enrolled into private health insurance plans through Cover Oregon, which in many cases took as long as five months to accomplish. In addition, nobody knows how many of those folks actually followed through and paid a monthly premium.
But it's a smashing success. Really!
