Florida Workers' Compensation Reimbursement Disputes: Provider Petition Guide

Florida separates a provider reimbursement dispute from an injured employee's claim for benefits. The provider dispute asks whether the carrier properly disallowed or adjusted payment for treatment already billed. It is governed by section 440.13(7) and the Division of Workers' Compensation's utilization and reimbursement dispute rules, not by a generic payer appeal letter.

This guide summarizes the 2026 Florida Statutes and the latest adopted rules shown in Florida Administrative Code chapter 69L-31 as of September 23, 2026. It is written for provider billing, revenue-cycle, and reimbursement teams and does not determine whether any specific service was authorized, compensable, medically necessary, correctly coded, or payable.

Florida reimbursement-dispute timeline

1. Confirm the dispute is a provider reimbursement matter

Section 440.13 defines a reimbursement dispute as a disagreement between a health care provider or facility and a carrier concerning payment for medical treatment. Subsection (6) authorizes carriers to review bills for overutilization, billing errors, and compliance with applicable practice parameters and protocols. A carrier that identifies an issue may disallow or adjust payment without first obtaining an order, if it complies with the statute and department rules.

Do not use the 60-day provider petition as a substitute for every unpaid workers' compensation bill. Identify the carrier action being challenged, the statutory or fee-schedule issue, and the precise amount in dispute. If the problem is missing authorization, an unprocessed clean bill, or a claim-level coverage issue, route it to the correct process while preserving any applicable deadline.

2. Preserve authorization and treatment-report evidence

Authorization is often outcome-determinative before the reimbursement calculation is reached. Section 440.13(3) generally makes carrier authorization a condition of provider payment, except for emergency care. It also requires an authorized provider's request for authorization to receive a carrier response by the close of the third business day. The statute contains distinct rules for written referral requests, emergency notification, referrals to other providers, and specified specialty services costing more than $1,000.

Section 440.13(4) separately requires treatment reporting. The statute states that a medical or surgical treatment claim is not valid or enforceable unless the physician provides the preliminary injury-and-treatment notice by the close of the third business day after first treatment and a complete report within 15 days, followed by requested progress reports. A reimbursement packet should therefore show both authorization and reporting compliance rather than assuming a carrier portal status proves the entire record.

• Carrier authorization number, date, scope, and any limitation on visits, services, body parts, or provider.
• The written authorization request and evidence of the carrier's receipt and response time.
• Emergency-care notice, including the third-business-day notice and 24-hour telephone notice if the emergency treatment resulted in admission.
• Preliminary treatment notice, complete report, and requested progress reports.
• Referral authorization and the underlying order when another provider, diagnostic facility, or therapy center was used.
• The exact bill file, submission date, clearinghouse acceptance, and carrier remittance or adjustment notice.

3. Calculate the 60-day petition period from receipt

The provider's 60-day period begins after receipt of the notice of disallowance or adjustment, not the service date or original bill date. Date-stamp the complete notice, preserve the envelope or electronic-delivery record, and calculate the filing date conservatively. Florida Administrative Code rule 69L-31.008 governs computation of time for this chapter, so the live rule should be checked when a deadline falls near a weekend, legal holiday, or delivery question.

4. Use the current DWC petition form

Rule 69L-31.003 adopts the Petition for Resolution of Reimbursement Dispute form identified by the Florida rules system as DFS-F6-DWC-3160-0023. The Florida Administrative Rules website lists the latest adopted version of rule 69L-31.003 as effective August 2, 2021 and also shows a rule-development notice published July 24, 2026. Because proposed development is not the same as an adopted change, providers should confirm the current final rule and form immediately before filing rather than relying on a saved template.

1. Identify the provider, carrier, employer, injured worker, accident date, claim number, dates of service, and affected bill lines.
2. Attach the complete notice of disallowance or adjustment and proof of when it was received.
3. State the precise reimbursement issue and amount contested for each line.
4. Attach the original bill, coding detail, authorization, treatment reports, clinical support, and transmission evidence.
5. Identify the applicable fee schedule, contract term, modifier, practice parameter, or other authority supporting the requested amount.
6. Reconcile prior payments, offsets, corrections, and remaining balance in a line-level schedule.
7. Quality-check the form and every exhibit before filing because omitted supporting documentation can lead to dismissal.

5. Serve every required party using a permitted tracked method

Section 440.13(7)(a) requires the petitioner to serve a copy on the carrier and all affected parties listed on the notice of disallowance or adjustment. Service must use U.S. Postal Service certified mail or a common carrier with verifiable tracking. Rule 69L-31.007 supplies additional service requirements. An internal email or ordinary mail log should not be treated as a substitute for the statutory method.

• Use the carrier and affected-party names and addresses shown on the operative notice, after checking for an updated designated address.
• Serve the same petition and exhibits submitted to the department; maintain a version hash or final packet copy.
• Retain mailing receipts, tracking numbers, delivery confirmations, and returned-mail evidence.
• Record the service date for each recipient rather than one generic completion date.
• Escalate any failed delivery immediately while the statutory period remains open.

6. Build evidence around the carrier's stated reason

A large attachment set is not necessarily a persuasive record. The petition narrative should connect each exhibit to the carrier reason, the disputed line, and the relief requested. Avoid including unrelated medical history merely because it is available.

7. Track the carrier response and department determination

The carrier must submit documentation substantiating its action within 45 days after receiving the petition. Under section 440.13(7)(b), failure to submit that documentation timely constitutes a waiver of all objections to the petition. The department must provide a written determination within 120 days after receiving all documentation, guided by the statute, reimbursement schedules, practice parameters, and treatment protocols.

If the department finds an improper disallowance or adjustment, subsection (7)(d) requires insurer reimbursement within 30 days. Subsection (11) gives the department exclusive jurisdiction over reimbursement matters and specified overutilization disputes. A team should route the written determination for legal review before attempting any further challenge; do not assume an employee-benefit appeal route applies to the provider's reimbursement decision.

Provider petition quality checklist

• The disputed carrier action fits a provider reimbursement dispute.

• The current DFS-F6-DWC-3160 petition form and current chapter 69L-31 rules were checked.
• Every disputed line, amount, reason, and requested correction is identified.
• Authorization, reporting, billing, clinical, fee-schedule, and payment evidence is complete and indexed.
• The carrier and all affected parties were served through a permitted tracked method.
• The filed and served packets are identical and preserved.
• Carrier response, record-completion, determination, and payment dates are calendared.
