Understanding the 6-step IDR process

Step 1. Start a dispute

  • Go to the IDR Initiation Form to start a dispute.
  • Be sure to have information available to identify the qualified IDR items or services. You will need to attest that the qualified IDR items or services are within the scope of the Federal IDR process.
  • To speed up the review of the dispute, include all information and documentation that is relevant and specific to the dispute.
  • Select your preferred certified IDR entity.

Step 2. Objections to the eligibility of the dispute

  • If a party objects to the eligibility of a dispute, this should be included in the IDRE Selection Response Form. You should provide documentation to support the eligibility objections. Objections should not be made after the selection of the IDRE.

Step 3. IDRE assignment notification

  • Once finalized, the CMS portal sends an email to both parties notifying them of the assigned IDRE.
  • Once both parties receive an email regarding the assigned IDRE, the IDRE receives the dispute.

Step 4. Request for payment of fees

  • If a dispute is determined eligible, Maximus will request payment for the administrative fee and entity fee via email invoice. 
  • Invoices can also be accessed on the payment portal.
  • If a dispute is determined to be ineligible for the Federal IDR process, Maximus will request payment for the administrative fee only. 45 CFR 149.510(d)(2)(i).
  • To learn more about the payment portal, go to our resources page.

Step 5. Notice of offer

  • If a dispute is determined eligible, the Federal IDR Portal will send an email to the parties notifying them that an offer is due; the email will contain a link by which a party can submit an offer and supporting offer documents.

Step 6. Resolution of dispute

  • After the deadline for submitting payments and offers has passed, Maximus will move forward with the resolution of the dispute. A written decision will be issued to the parties via email.

Eligibility overview

The No Surprises Act (NSA), effective January 1, 2022, provides billing protections to patients when receiving emergency care, non-emergency care from out-of-network (OON) providers, and air ambulance services from OON providers.

The NSA established the Independent Dispute Resolution process as a mechanism for providers and payors to determine the appropriate OON payment rate for items and services subject to the surprise billing protections in the NSA.

Maximus serves as an Independent Dispute Resolution Entity to resolve disputes between the OON provider and the health insurance plan.

For Maximus to render a payment determination for a dispute, the dispute must follow specific eligibility guidelines set forth in the NSA.

The items or services in dispute must fall into the three main categories specified in the NSA to be eligible for the IDR process:

  • Covered emergency services by an out-of-network provider/facility.
  • Covered non-emergency services from an out-of-network provider delivered as part of a patient’s visit to an in-network facility.
  • Covered services from out-of-network providers of air ambulance services.

Item/services in dispute must have been furnished after the NSA being enacted on January 1, 2022

Additionally, the IDR process requires certain timeframes, required steps, and specific guidelines for all items/services in dispute to be eligible for the IDR process:

  • Open Negotiation: All parties must go through a 30-business-day open negotiation period prior to starting the Federal IDR process.
  • Notice of IDR Initiation: The initiating party must submit the required forms to start the Federal IDR process within 4 business days after the end of the 30-business-day open negotiation period.
  • Specified State Law or All-Payer Model Agreement: In some states, the Federal IDR process is surpassed by a Specified State Law or All-Payer Model Agreement that provides a method for determining the total OON amount payable. Learn more about determining the applicability of the Federal IDR Process here: Basic State - Territory IDR Deeming Chart
  • Non-eligible circumstances: The NSA protections do not apply to the following:
    • Certain government programs such as Medicare, Medicaid, Indian Health Service, Veterans Affairs Health Care, and Tricare
    • Not covered items/services under the health plan
    • Ground ambulance services
    • Certain types of health plans, such as short-term plans, retiree-only plans, workers’ compensation plans, etc.

To facilitate your eligibility review, please include all important documentation, such as:

  • Complete Explanation of Benefits letters
  • Proof of submission of forms with dates and recipients, including: Proof of initiating open negotiation (including email or screenshot of email reflecting that the Open Negotiation Notice was sent to the non-initiating party) and Proof of Independent Dispute Resolution initiation (including email or screenshot of email reflecting that the Notice of IDR initiation was sent to the non-initiating party)
  • Member ID Card (if applicable)
  • UB-04 Form (for bundled disputes)
  • CMS extension documentation confirming extension approval
  • Prior payment determination containing the same disputing parties, service code, and date the cooling-off period began

Eligibility guidelines

Bundling disputes involves combining related services into a single dispute, while batching rules permit grouping similar claims under specific criteria to streamline resolution. After a decision is made, a "cooling off period" prevents the same parties from submitting similar disputes for 90 days to discourage repetitive filings.

A bundled payment arrangement is an arrangement under which:

  • A provider, facility, or provider of air ambulance services bills for multiple items or services furnished to a single patient under a single service code that represents multiple items or services (for example, a diagnostic related group (DRG) code); or
  • A plan or issuer makes an initial payment or notice of denial of payment to a provider, facility, or provider of air ambulance services under a single service code that represents multiple items or services furnished to a single patient (for example, a DRG code).

Disputes may be bundled by a single CPT, DRG, or HCPCS code.

Bundled payment arrangements are subject to the certified IDR entity fee and administrative fee for single determinations.

Initiating parties can batch multiple item or services under the same dispute as long as they meet the batching criteria. Batching items/services helps to decrease the number of IDR proceedings, avoids unnecessary complications from single disputes from plans and providers, and streamlines certified IDR entity decision-making.

Maximus current batching rules are in alignment with those as stated in 45 CFR 149.510(c)(3) and clarified in the Technical Assistance for Certified IDR Entities (August 2022). Maximus has implemented the following criteria for batching claims (all four must be met):

  1. The qualified IDR items or services are billed by the same provider, group of providers, facility, or provider of air ambulance services, under the same National Provider Identifier (NPI) or Taxpayer Identification Number (TIN)
  2. Payment (or notice of denial of payment) is made by the same group health plan, health insurance issuer, or Federal Employees Health Benefits (FEHB) carrier 
    1. For fully insured health plans, this means that qualified IDR items or services can be batched if payment is made by the same issuer, even if the qualified IDR items and services relate to claims from different fully insured group or individual health plan coverage offered by the issuer
    2. For self-insured group health plans, qualified IDR items or services can be batched only if payment is made by the same plan, even if the same third- party administrator (TPA) administers multiple self-insured plans
  3. The qualified IDR items or services are the same or similar items or services 
    1. To be the “same or similar”, the qualifying IDR items or services must be billed under the same service code with modifiers, or billed under comparable codes with modifiers under a different procedural code system. A comparable code under a different procedural code system is a code that, along with any relevant modifiers, indicates an identical item or service
    2. Coding systems that could be used to describe a qualified IDR item or service, including the Current Procedural Terminology (CPT) Coding System, the Healthcare Common Procedure Coding System (HCPCS), and the Diagnosis-Related Group (DRG) Coding System
  4. The qualified IDR items or services were furnished within the same 30-business-day period (or are items or services for which the open negotiation period expired during the same 90-calendar-day cooling-off period)

Please note, the revised definition of batched qualified IDR items or services as finalized in the Federal IDR Operations Final Rule (CMS-9897-F) will apply to disputes with open negotiation periods beginning on or after November 1, 2026:

  1. The qualified IDR items and services are considered paid by the same plan or issuer when: 
    1. For fully insured group health plans and individual health insurance coverage, the same issuer is required to make payment for the qualified IDR items and services, even if the qualified IDR items and services relate to claims from different insured group health plans or individual market policies
    2. For self-insured group health plans, the same self-insured group health plan is required to make payment for the qualified IDR items and services, including when the plan makes payments through a TPA. Claims from multiple self-insured group plans using the same TPA may not be batched, as they are not considered paid by the same plan
  2. The qualified IDR items and services are considered related to the treatment of a similar condition when: 
    1. They are furnished to a single patient, during the same patient encounter. A single patient encounter is defined as a single patient encounter on one or more consecutive days during which the qualified IDR items or services were furnished to the same patient and billed on the same claim form
    2. They are furnished to one or more patients and billed under the same service code or a comparable code under a different procedural code system, such as CPT codes with modifiers, if applicable, HCPCS with modifiers, if applicable, or DRG codes with modifiers, if applicable
    3. For anesthesiology, radiology, pathology, and laboratory qualified IDR items and services, they are furnished to one or more patients and were billed under service codes belonging to the same Category I CPT code ranges
  3. Batched qualified IDR items and services must be furnished within the same 30-business-day period following the date on which the first item or service included in the batched determination was furnished and have been the subject of a 30-business-day open negotiation period that ended within 4 business days of IDR initiation (the cooling off period specifically for batched disputes will be reduced from 90 calendar days to 30 business days)

The “Cooling-off period” is the 90-calendar day period following a payment determination when the initiating party cannot submit another Notice of IDR Initiation for the same or similar item or service involving the same non-initiating party from the previous payment determination.

The cooling-off period is applicable when the three criteria below are met:

  • Same parties
  • A payment determination was made on the previous dispute
  • The new dispute involves the same or similar items/services as the previous payment determination

A subsequent submission is permitted for the same or similar items or services if the end of the open negotiation period occurs during the 90-calendar-day cooling-off period. For these items or services, either party must submit the Notice of IDR Initiation within 30 business days following the end of the cooling-off period, as opposed to the standard 4-business-day period following the end of the open negotiation period. The 30-business-day period begins on the day after the last day of the cooling-off period.

Note: If the End of Open Negotiation is before the date of the previous rendered payment determination, cooling off will not be applicable for the new Notice of IDR Initiation.
