Three Republican U.S. House members said Hawaii’s health insurance exchange didn’t complete required security testing prior to launching on Oct. 15, potentially placing consumers at risk of identity theft and fraud.

A letter sent Tuesday to Gov. Neil Abercrombie by U.S. Reps. Darrell Issa of California, Jim Jordan of Ohio and James Lankford of Oklahoma requested that Abercrombie provide documents related to Hawaii’s exchange as part of an investigation into the rollout of the federal and state exchanges, the cornerstone of President Barack Obama’s Affordable Care Act. Since Oct. 1, Americans have been giving their personal information, such as birth dates, Social Security numbers and income, when signing up for coverage through the exchanges.

The letter was sent to Hawaii and nine other states, which the authors say had inadequate security testing.

"According to information provided by the Centers for Medicare and Medicaid Services, Hawaii’s Obamacare exchange did not have a security assessment prior to its launch," the letter stated.

Sanjeev "Sonny" Bhagowalia, the state of Hawaii’s chief adviser on technology and cybersecurity, said that is not true.

"Hawaii’s Exchange passed all security certifications required by the Centers for Medicare and Medicaid Services prior to launch on Oct. 15 and has had no security breaches since that time," Bhagowalia said in an email.

Tom Matsuda, interim head of Hawaii’s health insurance exchange, known as the Hawaii Health Connector, will go to Washington next week to testify before the House Oversight and Government Reform Committee, chaired by Issa. 

"The Connector takes very seriously any allegations about security of customer information and the integrity of our program," Matsuda said in a statement. "The information the residents of Hawaii have provided through the enrollment process is carefully safeguarded following the highest standards. While we are committed to providing any and all relevant information to adequately respond to this inquiry, it is disappointing to see these attempts to divert attention away from enrollment as we approach March 31 (the deadline for signing up for Obamacare)."

In addition to the security issue, Issa’s letter to Abercrombie, which the House Oversight Committee sent to journalists, said the Hawaii Health Connector has cost taxpayers millions with limited results.

"It is clear that the Hawaii exchange has failed to live up to expectations," the letter said. "Despite receiving over $205 million dollars in federal grants to set up its Obamacare exchange, the exchange has managed to enroll fewer than 5,000 people. Put differently, for every person enrolled by the exchange, federal taxpayers gave the state approximately $44,000 to set up the exchange. To date, Hawaii has signed up the fewest number of enrollees in the nation."
