Major health insurers say at least 80 percent of the people enrolled in their ObamaCare plans have paid their first premium.
Aetna, which offers ObamaCare plans in 17 states, told a House committee roughly 500,000 of their 600,000 enrollees had paid a premium by the third week of April.
Paul Wingle, an executive with Aetna, said the company's payment rate has been in the "low- to mid-80 percent range" and suggested it would rise.
Frank Coyne, a vice president of Blue Cross Blue Shield, also confirmed about 80 to 85 percent of their ObamaCare insured have so far paid their first premium.
Health insurance provider Wellpoint, which serves 14 federal and state exchanges, says up to 90 percent of those who have signed up for their plans and have met their premium deadlines have paid up.
However, when looking at total number of applicants who have signed up but have not necessarily hit their payment deadlines, Dennis Matheis a president at Wellpoint, said about 70 percent have made payments.
Darren Rodgers, senior vice president of Health Care Service Corporation, also testified before the committee that 83 to 93 percent of its ObamaCare enrollees have paid their premiums.
Cigna was the only insurance provider present at the meeting who could not provide data on premium payments.
Democrats are touting the administration's report that 8 million people have signed up for health insurance under the health law, but Republicans have argued at least a third of those enrolled have yet to pay for their insurance.
The insurers emphasized their enrollment numbers are not final.
