"We want to make sure people get paid timely and fairly but we can't have people take advantage of the system ," Scott said. "That's what was happening."
In 2010, Florida insurers paid a staggering $2.5 billion in PIP claims as auto insurance premiums , according to Scott, spiked 80% in South Florida.
Under the change, insurers were asked to lower auto insurance premiums by 10% in October and by 25% in 2014 unless they justified to the State of Florida why they couldn't be lowered.
Rice, who opened his practice in 1977, said fewer people would receive care because not everyone felt pain immediately after an auto accident.
"It's going to come out of their regular health insurance or out of their pockets or they're not going to get the care they need because they can't afford it ," he said. "The insurance companies are going to make out like bandits here. You're going to be paying for something you're not going to be able to access."
Critics cited a recent $100,000 donation to Scott's L et's Get To Work political committee as proof the changes were tilted in favor of insurance companies.
Some South Florida attorneys said they intended to challenge the law.
