Less than three weeks before a massive U.S. government health information database is scheduled to go live, some lawmakers have significant concerns about the ability of the system to protect personal health records and other private information.
It's unclear if security measures are in place at the U.S. Department of Health and Human Services' health exchange data hub, a huge IT system that will process uninsured U.S. residents' applications for health insurance, said Representative Patrick Meehan, a Pennsylvania Republican.
"I have grave concerns from a cybersecurity standpoint," Meehan said on Wednesday during a hearing of the cybersecurity subcommittee of the U.S. House of Representatives Homeland Security Committee.
The data hub, scheduled to go live Oct. 1, will process names, dates of birth, Social Security numbers, health conditions and several other pieces of personal information, Meehan said.
Other lawmakers raised similar fears about the hub, a key piece of the Affordable Care Act, often called Obamacare, passed by Congress in 2010. "The issue is not if but when we're going to have a breach of the data hub," said Representative Mike Rogers, an Alabama Republican.
But subcommittee Democrats noted that earlier this month the HHS Centers for Medicare and Medicaid Services (CMS) completed testing of the hub and received security authorization for the system. The security testing was established by the U.S. National Institute of Standards and Technology, according to CMS.
Representative Yvette Clarke, a New York Democrat, praised CMS for focusing on U.S. residents' privacy. State-operated health care exchanges, allowing uninsured people to shop for insurance, "will function only if people are certain that their private information — medical and financial — will be protected," she said.
Meehan questioned how CMS completed its security assessment nearly a month ahead of schedule after the agency had "for three years failed to meet a single deadline."
Critics have long raised concerns that the hub will collect large amounts of health and other personal information, and a breach could cause significant problems for users. Officials with President Barack Obama's administration have said the hub will store little information, instead accessing information in other databases as needed.
Data breaches at the hub would do "irreparable harm" to users, said Stephen Parente, director of the Medical Industry Leadership Institute at University of Minnesota. There hasn't been enough security testing on the hub, which is a "massive IT project with literally no technical precedent," he added.
Meehan on Wednesday repeated his concerns that the hub would make an attractive target for hackers. "We face a time in which we have very sophisticated adversaries ... who may wish to do us harm," he said.
But Matt Salo, executive director of the National Association of Medicaid Directors, said directors of state Medicaid programs have been working to ensure that the hub will be secure as their systems exchange data with it.
