Florida PIP Demand Letter Template: What § 627.736(10) Requires Before You Sue

By Jacob Greenberg

: added the demand letter template builder and checked every element against the 2026 Florida Statutes text of § 627.736(10). First published September 22, 2026.

Short answer: a Florida PIP demand letter is the written notice of intent to sue that Fla. Stat. § 627.736(10) requires before any action for PIP benefits. It must call itself a "demand letter under s. 627.736," name the insured, give the claim or policy number and the provider, itemize each exact amount with its date of service and type of benefit, and go by certified or registered mail, return receipt requested, to the insurer's designated address. The insurer then has 30 days after receipt to pay with interest and a penalty of up to $250. The free template builder below puts all of it on one printable page.

Florida is unusual among no-fault states in building a mandatory pre-suit step directly into the PIP statute. Before a provider (or attorney) can file an action for overdue or underpaid PIP benefits, Fla. Stat. § 627.736(10) requires a written demand letter — specific in form, sent to a specific place, with a defined cure window the insurer gets before litigation can proceed. A letter that misses a required element is a procedural defense handed to the insurer, regardless of whether the underlying underpayment is real.

This post is the deep, practical version of the demand-letter section in our broader PIP underpayments article — what the statute actually requires, what a demand-ready documentation package looks like, and where practices most often trip on form. (Educational content about billing mechanics and statutory requirements — not legal advice; a demand letter is a legal document and should be reviewed by counsel before it goes out.)

Why the Demand Letter Exists

§ 627.736(10)(a) makes written notice of an intent to initiate litigation a condition precedent to filing any action for PIP benefits, and bars sending it until the claim is overdue. The letter has to identify the insured, the claim or policy number, the provider and the itemized amounts claimed due, and the insurer then has 30 days after receipt to pay — with interest and a penalty — before suit can be brought.

The policy logic is straightforward: give the insurer one clean, documented chance to fix a legitimate error before both sides incur litigation costs. For providers, the practical upside is that a correctly itemized shortfall gives the insurer's claims desk an easy, low-risk decision: pay it now, or defend an arithmetic error later. The statute adds weight on the insurer's side too — under § 627.736(11)(a)2., an insurer that, as a general business practice, pays valid claims only after receiving a demand letter is engaging in an unfair or deceptive practice.

What the Letter Must Contain

The statute is specific about form, and each element is independently checkable. Under § 627.736(10)(b) and (c), a PIP demand letter needs:

  • The words "demand letter under s. 627.736." The notice must state that it is one.
  • The name of the insured — and, if the claimant is not the insured (a provider under an assignment of benefits), a copy of the assignment.
  • The claim number or policy number the claim was originally submitted under.
  • The specific amount claimed to be due, itemized: each exact amount, the date of treatment or service, and the type of benefit claimed. A vague assertion that "the claim was underpaid" without a dollar figure does not satisfy the requirement. A completed claim form under § 627.736(5)(d) may serve as the itemized statement.
  • The medical provider who rendered the treatment, to the extent applicable.
  • Sent to the correct person and address. Each insurer files a designated person and address for these notices with the Florida Office of Insurance Regulation; sending the demand to a generic claims department instead is a common, avoidable defect.

None of this is exotic, but a demand letter missing one element hands the insurer's defense counsel a procedural argument that has nothing to do with whether the underlying claim was actually underpaid. The builder below will not call a letter complete until every one of these elements is filled in.

Build your demand letter

Type the details and the builder writes the letter, totals the itemized lines, and works out the dates the statute sets: the earliest day you may send it, the end of the insurer's 30-day window, and the end of the 30-business-day tolling period. It lists any required element that is still missing, with the subsection that requires it.

Building the Itemization: The Part That Actually Wins the Dispute

The statute requires an itemized demand; it doesn't specify the format, which means the quality of the itemization is where disputes are actually settled inside the 30-day window. A demand package that gives the insurer's adjuster everything needed to verify the shortfall in five minutes is easier to pay than one that makes them do the work themselves.

A strong itemization, line by line per date of service, includes:

  • CPT code billed and the amount charged
  • The correct-year, correct-locality Medicare Part B participating allowable used in the fee-schedule calculation (see our fee schedule calculator guide for the exact formula and how to source this figure)
  • The computed payable amount: allowable × 200% × 80%
  • What the insurer actually paid on that line
  • The resulting shortfall, and a running total across all disputed lines
  • Supporting documentation: the original EOB, proof of timely submission, and any medical necessity documentation the insurer's remark codes call into question

This is exactly the re-pricing discipline covered in our underpayments article — the demand letter is where that re-pricing work gets packaged into something the insurer has to respond to on the record.

The 30-Day Cure Window: What Happens During It

Once the demand is received, the insurer has 30 days to pay the overdue claim together with applicable interest and a penalty of 10 percent of the overdue amount paid, capped at $250 (§ 627.736(10)(d)). A few practical realities of that window:

  • The mail method is not optional. The statute requires United States certified or registered mail, return receipt requested (§ 627.736(10)(c)). The signed return receipt dates the insurer's receipt, which is when the 30 days start. You may also ask, in the letter, for the postage to be reimbursed when the insurer pays.
  • Partial payment during the window is common. An insurer that agrees some lines were underpaid but disputes others may pay the undisputed portion and respond on the rest — track this per line, not as a single yes/no outcome. If the insurer decides not to pay an amount, the penalty is not payable in a later action.
  • Interest runs from the original notice. Overdue payments bear simple interest at the s. 55.03 rate or the contract rate, whichever is greater, calculated from the date the insurer had written notice of the loss (§ 627.736(4)(d)).
  • The limitation period is tolled for 30 business days by the mailing of the notice (§ 627.736(10)(e)).
  • Silence is not resolution. If the window closes with no payment, the letter has done its job: it created the documented pre-suit record § 627.736(10) requires, and the path to litigation is open if the practice or its attorney chooses to pursue it.

Building a Demand-Ready Practice, Not a One-Off Letter

The practices that get demand letters out fast aren't building the itemization from scratch every time. They're demand-ready by default: EOBs re-priced against the fee schedule as a matter of routine (not just when a dispute is already brewing), a per-patient benefit ledger that makes exhaustion and payment history a lookup rather than a reconstruction project, and documentation filed contemporaneously rather than assembled under deadline pressure months later.

That posture is the same billing discipline covered across this whole cluster — fee-schedule accuracy from the calculator guide, exhaustion tracking from the underpayments article, and clean documentation habits from our piece on Letters of Protection billing. A demand letter is just the moment all of that documentation gets tested.

If your practice is sitting on a stack of "resolved" PIP EOBs you've never actually re-priced, that's the starting point — not a demand letter yet, just an honest look at whether one is warranted. ClaimCarePro builds demand-ready documentation into our standard PIP billing workflow for Tampa Bay and Pinellas County practices, on a 10% contingency for underpayment recovery — no recovery, no fee — as part of our Clearwater denial management service.

Frequently asked questions

What must a Florida PIP demand letter include?

Under Fla. Stat. 627.736(10)(b), it must say it is a "demand letter under s. 627.736" and state with specificity: the name of the insured (with a copy of the assignment if the claimant is not the insured), the claim number or policy number, the name of the medical provider, and an itemized statement of each exact amount, the date of treatment or service, and the type of benefit claimed to be due.

How must a PIP demand letter be sent?

By United States certified or registered mail, return receipt requested, to the person and address the insurer designated for these notices (627.736(10)(c)). Insurers file that designee with the Office of Insurance Regulation; if none is designated, the name and address on file under s. 624.422 is deemed the authorized representative.

When can I send a PIP demand letter?

Only after the claim is overdue, including any additional time the insurer has to pay under 627.736(4)(b) (627.736(10)(a)). A claim is overdue if not paid within 30 days after the insurer is furnished written notice of the covered loss and its amount, so day 31 is the earliest.

What happens in the 30 days after the insurer gets the letter?

If the insurer pays the overdue amount with applicable interest and a penalty of 10 percent of the overdue amount paid (maximum $250) within 30 days after receipt, no action may be brought (627.736(10)(d)). If it decides not to pay an amount, the penalty is not payable in a later action.

Does the demand letter stop the statute of limitations?

It tolls it for 30 business days from the mailing of the notice (627.736(10)(e)).

Is the template on this page a legal form?

No. It is a template built from the statute text so every required element is present. Have your attorney review it before you send it. This page is not legal advice.

Does the builder save or send what I type?

No. The builder runs entirely in your browser. Nothing is uploaded, stored or tracked, and the letter is gone when you close the tab. Print it or copy it before you leave.

Is date of loss required in a PIP demand letter?

Date of loss is not one of the elements listed in 627.736(10)(b). It is a useful identifier for the insurer, so the builder offers it as an optional field.
