The information on payments comes from reports filed by the companies with state regulators and a national association — data that is not released to the public.

Regulators across the country collect troves of data about the performance of companies. It is assembled by the National Association of Insurance Commissioners.

Companies have claimed some of the data is a trade secret, and the association has resisted efforts at more transparency. Weiss says his company posts the information it purchased from the National Association of Insurance Commissioners on its website for Florida-specific insurers.

“A consumer, before buying a policy from a company, should know right up front what percentage of claims are being denied,” Weiss said. “We’ll be glad to make that number public, but we’d much prefer either the authorities or the company do that job.”
