The sticker shock of double-digit Obamacare rate hikes has left many New Yorkers reeling, worried whether increased health-care bills will put them in the poor house.

“With me being on a fixed income and my wife working part time, I’m not sure how we’re going to afford this increase,” said John Scaturro of Washington Heights, whose wife Lorette is a breast cancer survivor.

Lorette, 59, is already sacrificing — paying $656 a month on a joint annual income of $58,000 — to get the best coverage available from Oxford Health Plans.

But Oxford has notified her that it’s canceling her policy for 2017 — and a replacement could cost as much as $839 a month.

United Health Plans, the parent of Oxford, will continue to offer individual coverage in New York, just not under the Oxford brand, said spokeswoman Maria Gordon Shydlo.

The state has approved rate increases of up to 28 percent for United Health individual policies next year, part of a rate hike averaging 16.6 percent for the 17 companies offering Obamacare coverage in New York.

Under that scenario, if Lorette signs up for comparable coverage from United, her premiums could go up by $183 a month.

That’s got her worried about paying the bills while keeping her roster of doctors.

Lorette had worked as a full-time travel agent. Two years ago she booked Mayor de Blasio’s family vacation to Italy.

But she was laid off in March and is fearful of what’s ahead.

“I’m between a rock and a hard place for insurance. The reasonable rates go out the window,” she said.

Also fretting is Janice Proud, 63, of Peekskill, who was floored by the letter she received from her insurer, Affinity, boosting her premiums by 21 percent, from $544 to $658 a month.

“I was flabbergasted. I expected an increase — maybe 5%, not 21%,” said the self-employed graphic designer.

She earns $66,000 a year and is not eligible for a government subsidy. “I’m your average middle-class person. This is a lot of money, for sure,” she said.

Proud said she has little choice but to pay up to maintain coverage until she qualifies for Medicare at 65.

Some younger workers are forgoing coverage altogether.

“We have a lot of young people. They can’t afford it. They take a chance. They go without insurance,” said Elena Solitario, owner of Pilot Arts Beauty Shop in Brooklyn.

Regulators cited rising medical and drug costs to justify the hikes.

The state approved the increases after a health-insurance co-op, Health Republic, abruptly went bankrupt last year, forcing tens of thousands of its customers to scramble for coverage.

Regulators even approved higher rate increases than some insurers initially requested. Metro Plus, the health insurance arm of the city’s municipal hospital system, asked for 20.3 percent and was granted 29.2.

During the debate over health-care reform, President Obama vowed that the Affordable Care Act would increase medical access to the uninsured and under-insured. Health care experts credit Obama with boosting the insurance rolls, but claim the ACA has failed to control escalating costs.
