New York’s largest hospital network is quitting the insurance market — another victim of ObamaCare.

Northwell Health, formerly North Shore-LIJ Health System, is closing its CareConnect Insurance unit because it looks like a permanent money-loser, says CEO Michael J. Dowling. He blames ObamaCare “regulatory flaws that have destabilized insurance markets” and the feds’ “refusal to honor promises of additional funding.”

The “flaws” include rules that forced the company to pay more than 40 percent of its insurance revenues into a “risk adjustment pool” to bail out other insurers. The broken “promises” point to a law that cut back federal subsidies for insurers who set low premiums.

Half of CareConnect’s 126,000 customers are covered via employers in the small-group (100 employees or less) market; the rest are split between the large-group and individual markets. They’ll have a year to get new insurance, though many won’t find policies as good.

The company opened CareConnect in 2013 to cut out the insurance-company middlemen so it could “offer consumers affordable access to excellent care,” as Dowling put it. But the risk-adjustment rules had it sending more than $100 million a year to the major insurers it had tried to end-run.

You can blame Republicans in Congress for cutting the taxpayer subsidies that Democrats had promised, but that amount was smaller than what the Democrats were forcing it to pay to other insurers with their ObamaCare rule.

Partisan war in Washington is further destabilizing the health-insurance markets — but it’s the ObamaCare law that put those markets at Washington’s mercy, even as it greatly added to the polarization.

Plus: ObamaCare only works with massive taxpayer subsidies not just for people buying exchange policies, but also to insurers — and that’s just to maintain pre-Obama enrollment levels. (The net gains in coverage under the law come from Medicaid expansion.)

The whole house of cards is barely holding together, but the left, led by Sens. Bernie Sanders and Elizabeth Warren, wants to “fix” it by imposing single-payer healthcare — which would require vastly more federal spending.

Worse, it would plant the entire health-care system in the middle of the Washington crossfire. How is that a solution?
