The U.S. health insurance site has been sending faulty details to insurers that may heavily affect the applicants.

The Health Service site has been sending flawed information about applicants to over-burdened insurers. There is duplication, faulty information, missing data and wrong eligibility criteria.

The Patient Protection and Affordable Care Act requires every American to get a medical insurance under the Human Health Service (HHS) by this year. The misinterpreted data is resulting in lesser people being able to take insurance coverage.

The Human Health Service department in charge of the insurance exchange site has refused to address any of the faults or glitches. "We know that people are enrolling in coverage and the system works. As individual problems are raised by insurers, we work aggressively to address them," said Joanne Peters, spokeswoman of HHS, reports Wall Street Journal.

Executives at multiple insurance companies claimed that the HHS department had pressurized them not to publicize the issues. However, HHS has completely denied the claim.

More than 209,000 applicants have tried to register on the healthcare site this week but only one quarter of the people could successfully log in. Sometimes it takes even more than an hour to enroll on the site, reveals a recent post on Daily Mail.

The healthcare plan, launched on Oct.1, despite the shutdown, has been handicapped due to the technical difficulties that Kathleen Sebeliusm, the healthcare secretary, said were being looked into.

The Republicans are outraged at the Human Health Service department and have demanded that the Secretary step down.

"I wish they would explain what the technical problems are and how they intend to fix them," said Timothy Jost, a law professor at Washington and Lee University said in a statement.

The mis-matched information is bound to lead to chaos and will ultimately add to the health plan costs

The HHS blames the excessive traffic to the site this week due to the rush to get medical insurance done to meet the deadline.
