Hawaii PIP Medical Bills: Payment, Fee Schedule, and Dispute Guide

Coverage, medical necessity, claim proof, fee amount, and payment timing are separate controls. A provider should not begin with a generic appeal. The better approach is to verify the injured person's PIP claim and available benefits, prove receipt of a complete demand, classify every line, reproduce the applicable fee rule, and document the 60-day negotiation record.

This guide reflects Hawaii statutes and insurance guidance available October 9, 2026. It provides general operational information for healthcare providers and reimbursement teams and does not determine coverage, benefit exhaustion, medical necessity, reimbursement, standing, arbitration rights, or litigation strategy for a particular claim.

Hawaii PIP workflow at a glance

1. Confirm PIP coverage and remaining benefits

Hawaii Revised Statutes §431:10C-103.5 defines PIP benefits to include appropriate and reasonable medical and rehabilitative treatment and services, subject to the statute and policy. The required aggregate limit is $10,000 per person, but additional coverage may be purchased. The actual declarations page and benefit ledger—not the statutory minimum alone—control the operational review.

• Match the patient, insured, vehicle, accident date, and claim number.
• Confirm covered-person status and whether the injury arose from the motor vehicle accident.
• Obtain the policy's PIP limit and any additional coverage.
• Reconcile all prior medical payments and the current remaining benefit.
• Identify coordination, workers' compensation, health coverage, exclusions, or investigation issues.
• Record the insurer, adjuster, bill-review administrator, and each submission channel.

2. Submit reasonable proof and a documented demand

Section 431:10C-304 connects the payment deadline to the insurer's receipt of reasonable proof of the fact and amount of the covered benefit and a demand for payment. The provider's file should show what was sent, why the service is accident-related and appropriate, and when the insurer received it. A billing-system creation date is not proof of payer receipt.

1. Verify patient, policy, claim, accident, provider, and service identifiers.
2. Submit complete procedure codes, modifiers, units, diagnoses, charges, and place-of-service data.
3. Attach the clinical history, findings, orders, plan, progress, and reports supporting the service.
4. Include invoices, prescriptions, referrals, or other item-specific proof when relevant.
5. State a clear demand for payment and preserve the exact transmitted package.
6. Capture portal, clearinghouse, fax, mail, or other objective delivery and acceptance evidence.

3. Track the 30-day payment, denial, and information-request controls

Under §431:10C-304, PIP benefits are overdue if not paid within 30 days after the insurer receives reasonable proof and a demand. If the insurer denies a claim for benefits, it must provide written notice within 30 days, and for medical services it must provide a copy to the provider. If more information is needed, the insurer must send an itemized request within 30 days and provide a copy to the provider.

The statute provides interest of 1.5% per month on unpaid benefits beginning 30 days after the insurer receives reasonable proof and a demand. Any interest calculation should use the supported principal, receipt date, information chronology, later payments, and claim-specific legal analysis. It should not be generated solely from an aging report.

4. Reproduce the medical fee calculation

Section 431:10C-308.5 generally limits charges for services covered under Hawaii's motor vehicle insurance law by reference to the workers' compensation supplemental medical fee schedule. Emergency services provided within 72 hours after a motor vehicle accident are treated differently under the statute. When a covered service does not have a fee in the schedule, the statute generally uses 80% of the provider's usual and customary charge.

The fee rule does not independently prove coverage, accident causation, medical necessity, or available benefits. A provider should calculate the price issue separately and answer any clinical or coverage reason with the appropriate record. This prevents a good fee argument from being obscured by an unresolved proof issue.

5. Require payment of the undisputed amount

Section 431:10C-308.5 directs the insurer to pay undisputed charges within 30 days after receiving the bill and supporting documentation. When the insurer disputes a charge, it must pay the amount it believes is allowed and provide a written explanation of its position. The provider should reconcile this amount line by line and avoid treating a partial payment as a complete explanation.

• Tie each billed line to paid, reduced, denied, pending, duplicate, or exhausted status.
• Separate fee reductions from coverage or medical-necessity denials.
• Confirm whether the insurer paid its asserted allowed amount.
• Identify missing codes, units, modifiers, or service classifications in the explanation.
• Reconcile deposits, prior EOBs, refunds, patient payments, and the benefit ledger.
• Calculate only the remaining disputed principal before adding any claimed interest.

6. Build the 60-day good-faith negotiation record

For a disputed medical charge, §431:10C-308.5 requires the insurer to negotiate in good faith with the provider for no longer than 60 days. A negotiation packet should be narrow enough to review: identify the claim, disputed lines, insurer's position, provider's statutory calculation, clinical proof where relevant, payment received, and exact correction requested.

Maintain a dated log of proposals, calculations, documents, calls, emails, written responses, and unresolved points. Good-faith negotiation is more than repeating the billed charge or a payer allowance. Each side's position should be tied to a calculation, document, or authority. Providers should avoid claiming access to a payer's confidential methodology or representing an internal estimate as an official fee.

7. Escalate unresolved disputes after the negotiation period

If the disputed charge is not resolved within the statutory negotiation period, §431:10C-308.5 allows the provider, insurer, or claimant to submit the dispute to the insurance commissioner, arbitration, or a court of competent jurisdiction. The submission is to include documentation of the negotiation. Which path is available and appropriate—and who may invoke it—requires review of the current statute, rules, policy, assignment or authorization, amounts, and procedural history.

The same section prohibits the provider from collecting the disputed difference from the insured. Keep disputed PIP balances out of ordinary patient statements and collection workflows while the statutory restriction applies. An unresolved insurer-provider fee dispute should not become an accidental balance bill.
