PIP Suits in Florida: Demand Letter, Filing, and Attorney Fees

PIP lawsuits in Florida begin with a statutory pre-suit demand letter, followed by a 30-day waiting period, and only then a complaint filed in county or small claims court against the insurer that underpaid, delayed, or denied Personal Injury Protection benefits. The process is governed by Florida Statute § 627.736, and the economics of these cases shifted sharply in 2023 when the Legislature repealed the one-way attorney fee rule that had long made small PIP suits worth filing.¹

When You Can Sue Your PIP Insurer

Most PIP suits trace back to a handful of insurer behaviors. The carrier pays less than the required 80% of reasonable medical expenses or 60% of lost wages. It applies the wrong fee schedule, often using Medicare Part B reimbursement rates to shrink what a provider is owed. Or it simply misses the 30-day payment deadline that runs from the date it received notice of a covered loss and valid proof of the claim.¹

Denials based on an insurer-ordered medical examination are another common trigger. The insurer is entitled to require you to submit to a physical or mental examination at its expense, but it cannot cut off future treatment payments without a valid report from a Florida-licensed physician in the same specialty as your treating provider, stating that the treatment isn’t reasonable, related, or necessary.¹ Denials that skip that step, or that rely on a report from a physician in the wrong specialty, are ripe for challenge. Some of these examinations are only paper reviews of your records rather than in-person evaluations, which matters when you’re testing the denial’s validity.

Medical providers file many of these suits themselves rather than waiting on the patient. To do it, the provider needs a valid Assignment of Benefits signed by the patient, which transfers the right to receive insurance payments and gives the provider standing to sue.

The Pre-Suit Demand Letter

You cannot file a PIP lawsuit in Florida until you have sent the insurer a formal demand letter, and the claim must already be overdue when you send it. The letter has to go out by certified or registered mail, return receipt requested.²

The statute is specific about what has to appear in the letter:

A statement that this is a “demand letter under s. 627.736.”
The full name of the insured, plus a copy of any assignment of benefits if the claimant isn’t the insured.
The claim or policy number the claim was submitted under.
The name of the medical provider and an itemized statement listing each amount owed, each date of service, and the type of benefit claimed.

Delivery matters as much as content. The letter has to reach the specific person and address the insurer has designated for demand notices, and that designation is filed with the Office of Insurance Regulation and published online.² Sending it to the wrong address, or leaving out a required detail, can invalidate the letter and get your eventual lawsuit dismissed.

The 30-Day Response Window

Once the insurer receives the demand, it has 30 days to pay the overdue amount along with applicable interest and a penalty of 10% of the overdue amount, capped at $250. If it pays within that window, no lawsuit can be filed and the insurer owes no attorney fees.² Mailing the letter also tolls the statute of limitations for 30 business days, so the wait doesn’t cost you time.

Filing the Complaint and Serving the Insurer

When the 30 days end without adequate payment, you file the complaint. Because per-person PIP benefits are capped at $10,000, most disputes land in Small Claims Court for amounts up to $8,000 or County Court for amounts between $8,001 and $50,000.³ When accumulated interest and fees push the total above $50,000, the case can end up in Circuit Court, but that’s unusual for a single PIP dispute.

Service of process runs through a designated state official. Every authorized insurer doing business in Florida must designate the Chief Financial Officer of Florida as its statutory registered agent for service.⁴ After service, the insurer generally has 20 days to file its response, and the case then moves into discovery, where both sides exchange medical records, billing documentation, and the insurer’s claim file.

What Changed in 2023 for Attorney Fees

This is the part of the PIP landscape that shifted most. Before March 24, 2023, Florida Statute § 627.428 required an insurer that lost any amount to pay the plaintiff’s attorney fees. That one-way rule made small underpayments worth suing over, because the insurer carried the risk of paying both sides’ lawyers.

House Bill 837, signed into law on March 24, 2023, repealed that provision. For any policy that began or renewed after that date, the automatic one-way fee entitlement in PIP cases is gone. Fees haven’t disappeared entirely, but the remaining paths are narrower:

A proposal for settlement under Florida Statute § 768.79 can produce a fee award if the insurer rejects your offer and the judgment ends up at least 25% better than what you proposed.
When the insurer has denied coverage outright, the named insured (not a provider or assignee) can file a declaratory action to establish coverage, and a win there still carries fee-shifting.
Florida Statute § 57.105 allows fees as a sanction when the insurer’s defense wasn’t supported by the material facts or existing law.
The PIP statute allows the prevailing party to recover fees when insurance fraud tied to PIP coverage is proven.

The practical result: a fight over a few hundred dollars in underpaid benefits, which used to be worth pursuing, may no longer make economic sense unless it fits one of the remaining fee pathways. Plaintiffs and their lawyers are picking their cases more carefully.

What You Can Recover

A successful PIP suit recovers the unpaid benefits owed under the policy. On top of that base, all overdue payments carry simple interest at the rate set by the Office of Financial Regulation under Florida Statute § 55.03, or the rate stated in the policy, whichever is lower, running from the date each payment first became overdue.¹ A claim that sat unpaid for years accumulates meaningful additional recovery through that interest alone.

If the insurer had a chance to resolve things during the demand period and didn’t, the 10% penalty (up to $250) becomes part of the judgment as well.² The real financial pressure on insurers usually comes from the combination of interest, any fees recoverable through the remaining statutory avenues, and their own litigation costs.

Deadlines That Can End Your Case

A PIP policy is a written contract, so the five-year statute of limitations for actions on written instruments applies.⁵ The clock starts when the insurer’s obligation to pay came due, not on the date of the accident. Because PIP claims typically involve multiple treatments over time, individual line items on the same claim can have different limitation dates, and older charges can go stale even while newer ones remain timely. The demand letter’s 30 business day tolling helps at the margin but isn’t a reason to sit on the file.²

One earlier deadline to be aware of before you even reach the lawsuit stage: PIP requires that initial medical treatment be obtained within 14 days of the accident. Miss that window and PIP benefits are forfeited entirely, and no lawsuit can bring them back.¹

After a Recovery: Medicare and Taxes

Medicare beneficiaries have one more step. Medicare operates as a secondary payer, so it can recover conditional payments it made for accident-related treatment that PIP should have covered. You have to notify Medicare and repay conditional payments within 60 days of receiving a settlement or judgment. Medicare reduces its recovery by a proportionate share of your attorney fees and costs, and you can request a compromise or hardship waiver where the recovery is disproportionate. Ignore the lien and Medicare can pursue the overpayment directly, so it needs to be resolved before settlement funds are distributed.

On taxes, PIP benefits reimbursing medical expenses are excluded from gross income under Internal Revenue Code § 104(a)(2) as damages received on account of personal physical injuries.⁶ The interest and penalty portions of a judgment can be treated differently because they compensate for delay rather than injury. If your recovery includes interest, confirm the tax treatment with a tax professional before filing.
