Donovan Brown, state government relations counsel for the Property Casualty Insurers Association of America, says, "In order to address fraud and abuse within Florida's no-fault insurance system and provide Floridians relief from being the No. 1 state in the nation for questionable auto claims, it is imperative that consumers receive the benefits from the PIP reforms becoming fully effective."

PCI and other trade association filed court briefs in support of lifting the injunction. The industry has alleged PIP fraud costs Florida residents $1 billion.

Donovan says there is no timeframe for a decision from the court.

Some insurers—because the group of medical pros are suing the OIR, not insurers—are using provisions in HB 119, which aims to ban PIP to acupuncturists and massage facilities and requires that claimants seek treatment with 14 days of an accident from a hospital or physician.

Other insurers have yet to enact to measures in HB 119.

Meanwhile, Jeff Atwater, the Sunshine State's CFO, announced the arrests of three people for PIP fraud. 

"PIP fraud schemes drive up auto insurance rates for all Floridians, so we must do everything we can to put a stop to them," said Atwater, in a statement.

One person used fake media credentials to obtain accident reports he used to solicit accident victims. Another couple operated an unlicensed accident clinic.

Add this additional wrinkle to the PIP reform saga: the Legislative Session is just around the corner and some lawmakers are expected to contemplate repealing the PIP system entirely, says Brown.

Last session, legislation floated to end PIP but it did not gain momentum.
