Rescission was largely hidden until three years ago, when The Times launched a series of stories disclosing that insurers routinely canceled the medical coverage of individual policyholders who required expensive medical care.
Sassi said rescissions are necessary to prevent people who lie about preexisting conditions from obtaining coverage and driving up costs for others.
"I want to emphasize that rescission is about stopping fraud and material misrepresentations that contribute to spiraling healthcare costs," Sassi told the committee.
But rescission victims testified that their policies were canceled for inadvertent omissions or honest mistakes about medical history on their applications. Rescission, they said, was about improving corporate profits rather than rooting out fraud.
"It's about the money," said Jennifer Wittney Horton, a Los Angeles woman whose policy was rescinded after failure to report a weight-loss medication she was no longer taking and irregular menstruation.
"Insurers ignore the law, and when they find a discrepancy or omission, they rescind the policy and refuse to pay any of your medical bills -- even for routine treatment or treatment they previously authorized," Horton said.
She and others from around the country accused insurers in testimony of gaming anti-fraud laws to take policyholders' premiums, only to drop people who developed serious illnesses. They testified that they or a deceased loved one had had policies canceled over innocent mistakes and inadvertent omissions on their applications.
A Texas nurse said she lost her coverage, after she was diagnosed with aggressive breast cancer, for failing to disclose a visit to a dermatologist for acne.
The sister of an Illinois man who died of lymphoma said his policy was rescinded for the failure to report a possible aneurysm and gallstones that his physician noted in his chart but did not discuss with him.
The committee's investigation found that WellPoint's Blue Cross targeted individuals with more than 1,400 conditions, including breast cancer, lymphoma, pregnancy and high blood pressure. And the committee obtained documents that showed Blue Cross supervisors praised employees in performance reviews for rescinding policies.
One employee, for instance, received a perfect 5 for "exceptional performance" on an evaluation that noted the employee's role in dropping thousands of policyholders and avoiding nearly $10 million worth of medical care.
