Maryland recently moved to chuck its existing Obamacare technology and use software from Connecticut's own state-run health insurance exchange.
Other states, notably Hawaii and Massachusetts, are under pressure to either adopt new software for their troubled state-run exchanges or throw in the towel and let the federal exchange handle enrollments for residents of those states.
HealthCare,gov was designed to be scalable, meaning that it can adapt to states being added to the platform.
After Friday's vote by the Cover Oregon exchange's board, a spokesman for the federal agency that oversees HealthCare.gov said it "is committed to working closely with states to support their efforts in implementing a Marketplace that works best for their consumers."
"We are working with Oregon to ensure that all Oregonians have access to quality, affordable, health coverage in 2015," said the spokesman, Aaron Albright, of the Centers for Medicare and Medicaid Services.
The decision to move to the federal exchange will cost Oregon between $4 million to $6 million, as opposed to the $78 million that would have been needed to fix the current system, which as of now has been unable to enroll anyone online in one sitting.
Since it was created, Cover Oregon has spent nearly $182 million, and, in return, has gotten what is generally believed to be the worst online Obamacare exchange in the nation. The state is contemplating legal action against Oracle, the exchange's lead vendor.

The vote means that Oregon residents who want to obtain or renew individual Obamacare health insurance plans effective in 2015 will do so, beginning Nov. 15 through the HealthCare.gov portal. HealthCare.gov already handles enrollments for residents of 36 states that are not operating their own exchanges.
People whose low or moderate incomes qualify them for federal subsidies to offset the cost of individual insurance plans can only get those subsidies if they enroll in one of the plans sold on government-run exchanges.
The vote by the Cover Oregon, which was expected, came after the exchange's board heard that officials had considered 10 options for dealing with the problems of the marketplace.
The second preferred option—fixing the website and hiring a new system integrator—still would have left the exchange unable until next year to handle insurance sign-ups from people outside the open-enrollment period if they experience a qualifying life-change event, such as a job loss or marriage. And the cost of that option was too high, officials said.
