North Carolina Workers' Compensation Medical Fee Disputes: Form 26I Guide
A provider guide to North Carolina Form 26I fee disputes, the 20-day payer response, Medical Fees Section assistance, intervention, and Form 33I hearings.

Before you act on this guidance
- Check the controlling jurisdiction, coverage terms and current agency guidance; a published overview is not a determination for your claim.
- Prepare the relevant records: State, bill and EOB dates, fee-schedule issue and earlier review requests.
This process separates an ordinary billing follow-up from a Commission fee dispute. The provider must establish the claim relationship, document the amount and basis of the charge, give the payer the prescribed opportunity to respond, and preserve the evidence needed for later review. A demand that skips those steps may delay rather than accelerate resolution.
This guide reflects North Carolina Industrial Commission materials available October 1, 2026. It explains an operational workflow; it does not decide compensability, authorization, causation, coding, fee-schedule calculation, standing, or the amount owed on a specific claim.
North Carolina fee-dispute pathway at a glance
| Stage | Action | Key control |
|---|---|---|
| Initial billing | Submit an accurate bill and required documentation to the responsible employer or carrier | Retain the complete packet and reliable receipt evidence |
| Provider inquiry | Send Form 26I directly to the employer or carrier believed liable | Identify every disputed service, amount, and supporting record |
| Payer response | Allow the payer 20 days to respond to Form 26I | Calendar from documented receipt rather than the mailing date |
| Commission assistance | If there is no timely response or liability is denied, send the Form 26I packet and response, if any, to the Medical Fees Section | Include a concise calculation and dispute summary |
| Intervention | If informal efforts fail, consider a motion to intervene in an existing eligible claim | Confirm that a related claim exists and that injury liability is not denied or has been adjudicated for the employee |
| Hearing | After intervention is allowed, use Form 33I and the required filing fee | Preserve service, mediation, witness, and exhibit records |
1. Classify the dispute before using Form 26I
A payment variance is not automatically a medical-fee dispute. First determine whether the payer disputes the compensability of the injury, authorization of treatment, causal relationship, medical necessity, coding, documentation, or only the amount payable under the fee schedule or contract. The Medical Fees Section can assist with fee questions, but it does not turn an unresolved compensability issue into a simple pricing calculation.
- Confirm the employee, employer, carrier or administrator, claim number, injury date, and adjuster.
- Identify whether the underlying workers' compensation claim has been filed, accepted, denied, or adjudicated.
- Match authorization and referral records to each date of service.
- Separate unpaid bills from underpayments, duplicate denials, coding disputes, and documentation requests.
- Determine whether a contract supplies a different rate or payment method.
- Use the fee schedule in effect for the date and type of service.
2. Submit charges promptly and preserve receipt
N.C. Gen. Stat. § 97-26 directs providers to submit charges within 30 days after treatment, within 30 days after the end of the month when multiple treatments are provided, or within another reasonable period allowed by the Commission. Operational teams should not treat this as permission to wait. A prompt, complete submission creates a reliable record and gives the payer an opportunity to process the bill before escalation.
The same statute ties reimbursement to the Commission fee schedule unless a contract provides a different rate or method. If no fee schedule or contract applies, reimbursement is based on a usual, customary, and reasonable charge and may not exceed the provider's usual fee. When only part of a charge is disputed, the uncontested portion should be paid while the balance is resolved.
- Validate the claim and payer identifiers before transmitting the bill.
- Check codes, modifiers, units, dates of service, provider type, and place of service.
- Attach authorization, reports, records, and any documentation required for the service.
- Apply the current Commission schedule or document the relevant contract method.
- Transmit through a channel that produces a receipt or acknowledgement.
- Store the exact bill, attachments, transmission record, remittance, and explanation of payment.
3. Build and send the Form 26I packet
The Commission's Medical Provider Fee Dispute Resolution Procedure instructs the provider to submit Form 26I directly to the employer or carrier believed liable. The questionnaire should not be a bare cover page. It should be paired with the bill, payment or denial information, medical and authorization records relevant to the charge, fee-schedule or contract calculation, prior correspondence, and proof of delivery.
4. Track the 20-day payer response period
The Commission procedure gives the employer or carrier 20 days to respond to the provider's Form 26I. Record the payer's actual receipt date and calendar the response deadline. If a response arrives, analyze whether it resolves the matter, requests information, identifies a different responsible entity, disputes the calculation, or denies liability.
A partial response should be logged by disputed line and reason. Supply genuinely missing information promptly, but do not allow repeated informal exchanges to obscure the original submission, the payer's position, or the amounts that remain contested.
5. Request Medical Fees Section assistance
If the payer does not respond within 20 days or denies liability for the fee, the provider may ask the Medical Fees Section for assistance. Send a copy of the Form 26I packet, proof it was delivered to the payer, and the payer's response if one was received. Add a short chronology and a calculation that isolates the unresolved balance.
- Form 26I and every attachment sent to the payer.
- Proof of payer receipt and the 20-day deadline calculation.
- The payer's written response, EOB, remittance, or denial.
- The original and corrected bills, reports, authorization, and relevant records.
- The applicable fee-schedule or contract provision and line-by-line computation.
- A concise history of follow-up and the relief requested.
The Medical Fees Section attempts informal resolution. Providers should keep communications factual and limited to the disputed issues. Informal assistance is not a substitute for protecting any separate limitation period, hearing right, contractual remedy, or claim-specific legal position.
6. Understand the limits on intervention
If the dispute remains unresolved, the Commission procedure permits a provider to move to intervene in an existing claim. Intervention is not automatic. The procedure states that a motion will be granted only when a related workers' compensation claim has been filed and liability for the underlying injury is not denied or has been adjudicated in the employee's favor.
The motion should identify the Commission file number; employee and party information; only the last four digits of the employee's Social Security number; the injury and body parts; itemized charges and codes; the link between services and the injury; the Form 26I process; the request for Medical Fees Section assistance; a written dispute summary; a sworn affidavit; and certification that the required parties were served.
7. Review, hearing, and mediation controls
If intervention is denied, the procedure allows review by the Full Commission when the request is filed within 10 days after receipt of the denial, served on the parties, and includes the required statement and materials. Because this is a short procedural period, route the denial for immediate claim-specific review rather than leaving it in an ordinary accounts-receivable queue.
When intervention is allowed, the provider may request a hearing on Form 33I and pay the stated $200 filing fee. The matter is handled similarly to a Form 33 hearing and includes mediation. Verify the current form, fee, service requirements, and Commission instructions at the time of filing; do not rely on an internal checklist if an official form or rule has changed.
