Independent Dispute Resolution (IDR) for New York Healthcare Providers
Provider-side representation in federal IDR under the No Surprises Act and New York IDR under Financial Services Law Article 6. Out-of-network reimbursement disputes for emergency services, services at in-network facilities, and air ambulance claims. Strict deadlines apply — the federal initiation window is 4 business days after open negotiation closes.

⚠ IDR deadlines are short and unforgiving.
Federal IDR (No Surprises Act): 30 business days for open negotiation after the initial payment or denial, then a 4-business-day window to initiate IDR.
NY IDR (Surprise Bill Law): Submit the dispute to DFS within the timeframes set by 23 NYCRR Part 400 after the issuer’s payment determination.
Missing the open-negotiation period or the IDR initiation window forfeits the dispute — and triggers a 90-day cooling-off period during which the same item or service cannot be re-filed against the same payer (federal IDR). Engage counsel as soon as the underpayment is identified.
Two separate IDR systems operate in parallel for out-of-network reimbursement disputes affecting New York providers. Both go by “IDR.” They have different jurisdictions, deadlines, payment standards, and outcomes. Choosing the wrong process — or missing the threshold determination of which one applies — can forfeit the claim. The firm represents healthcare providers in both forums and handles the threshold eligibility analysis as part of every engagement.
Two Different IDR Systems — Which One Applies?
The first question in any IDR matter is jurisdictional. The plan type controls.
| Federal IDR (No Surprises Act) | New York IDR (Surprise Bill Law) | |
|---|---|---|
| Authority | Public Health Service Act § 2799A-1; 42 U.S.C. § 300gg-111 et seq.; 45 CFR Part 149 | Financial Services Law Article 6 (§§ 601–607); 23 NYCRR Part 400 |
| Plans covered | ERISA self-funded plans, federal employee plans (FEHB), and other federally regulated plans not subject to a specified state law | NY-regulated fully insured commercial plans, Article 43 corporations, HMOs, student health plans, municipal cooperative health benefit plans, and prepaid health services plans |
| Items eligible | Out-of-network emergency services, out-of-network non-emergency services at in-network facilities, and out-of-network air ambulance services | Out-of-network emergency services in hospital facilities (including inpatient services following an ER visit), surprise bills at participating hospitals or ambulatory surgical centers, and out-of-network referrals from a participating physician |
| Initiation | Federal IDR Portal at CMS, after 30-business-day open negotiation period, within a 4-business-day window | Submit to NY Department of Financial Services (DFS), which assigns a certified IDRE |
| Decision standard | Baseball-style arbitration: IDRE selects one of the two offers based on Qualifying Payment Amount (QPA) and statutory factors | “Reasonable fee” determination under FSL § 604, considering FAIR Health 80th percentile data, training and experience, complexity, and patient circumstances |
| Decision timeline | Generally 30 business days after IDRE selection (often longer in practice given backlogs) | Generally 30 days from receipt of the dispute |
| Cost allocation | Loser pays the certified IDR entity fee; both parties pay a non-refundable administrative fee | Loser pays the IDRE fee; split for split decisions |
| Cooling-off rule | 90-day cooling-off after a determination — the same item or service cannot be re-filed against the same payer for 90 days | No federal-style cooling-off rule; bound by 23 NYCRR Part 400 procedures |
New York has “specified state law” status under the No Surprises Act. When NY’s IDR process applies to a dispute (because the plan and service type fall within Article 6), federal IDR does not apply to that same dispute. Self-funded ERISA plans are usually not subject to NY law and are routed through federal IDR even for services rendered in New York.
Determining Eligibility
Threshold eligibility analysis covers four questions.
Plan type. Is the plan ERISA self-funded, fully insured, FEHB, Medicare/Medicaid, short-term limited duration, or some other category? ERISA self-funded usually = federal IDR. Fully insured NY plan usually = NY IDR. Government plans are generally outside both.
Item or service type. Federal IDR covers out-of-network emergency services, out-of-network ancillary services at in-network facilities (anesthesiology, radiology, pathology, neonatology, assistant surgeon, hospitalist, intensivist services), and out-of-network air ambulance. NY IDR covers similar categories with some scope differences, plus the out-of-network referral scenario when the referral comes from a participating physician.
Open negotiation outcome. Federal IDR is available only after a 30-business-day open negotiation period closes without resolution. Skipping or mishandling open negotiation forfeits the federal IDR option for that claim.
Specified State Law applicability. CMS publishes a Chart for Determining the Applicability for the Federal IDR Process. Where NY’s specified state law applies, that dispute is removed from federal IDR jurisdiction.
Out-of-network underpayment? The IDR clock starts the day the EOB arrives.

The Federal IDR Process — Step by Step
Initial Payment or Notice of Denial
The plan pays an initial amount or issues a notice of denial within 30 calendar days of the claim. This is the trigger that starts the IDR clock. Review the EOB carefully — the QPA, claim adjustment reason codes (CARCs), and remittance advice remark codes (RARCs) all feed into the dispute.
Open Negotiation Period — 30 Business Days
The provider initiates open negotiation by serving a written notice. The 30-business-day clock runs from the date of the notice. During open negotiation, the parties exchange offers and supporting information directly. Many disputes resolve here without IDR.
IDR Initiation — 4 Business Day Window
If open negotiation does not resolve the dispute, the provider has only 4 business days from the close of open negotiation to initiate IDR through the Federal IDR Portal. Late initiation forfeits the dispute. The Notice of IDR Initiation must include item and service information, plan information, QPA, and supporting documentation.
IDR Entity Selection
The parties have 3 business days to jointly select a certified IDR entity. If they cannot agree, the Departments randomly assign one. As of early 2026, sixteen certified IDR entities are available. Each has its own approach to evidence weighting and timeline management; selection matters.
Offer Submission — 10 Business Days
Each party submits a single payment offer along with supporting documentation: QPA explanation, training and experience evidence, market data, complexity factors, patient acuity, and any other information bearing on the appropriate out-of-network rate. The IDR is baseball-style — the IDRE picks one offer in full, not a midpoint. Offer strategy is the most consequential decision in the process.
IDRE Determination
The IDRE selects the prevailing offer, generally within 30 business days of selection (current portal backlogs frequently extend this). Payment of the difference is due within 30 calendar days of the determination. The losing party pays the IDRE fee; both parties pay a non-refundable administrative fee.
90-Day Cooling-Off Period
After a determination, the same items or services cannot be re-submitted to IDR against the same payer for 90 calendar days. Batching, bundling, and timing strategies should account for the cooling-off rule.
Batching and Bundling
Federal IDR allows providers to batch multiple disputes into a single proceeding when the items meet specific eligibility criteria: same payer, same service code or related code under the same procedure or condition, services furnished within a 30-business-day period, and other regulatory requirements. Proper batching dramatically lowers per-dispute economics. Improper batching results in dismissal — and can trigger the cooling-off rule against re-filing. The IDR Operations Rule (proposed November 2023, expected to be finalized in 2026) is anticipated to modify batching rules; the firm tracks rule changes as they take effect.
The New York IDR Process
NY IDR is administered by the Department of Financial Services under FSL Article 6 and 23 NYCRR Part 400. The procedural mechanics differ from federal IDR in several material respects.
Submission. Either the issuer or the provider may submit a dispute to DFS. DFS randomly assigns the dispute to a certified IDRE. NY does not use joint selection.
Reasonable fee standard. The IDRE determines whether the provider’s charge or the issuer’s payment is more reasonable, applying the criteria in FSL § 604: usual and customary cost (defined as the 80th percentile of all charges for the service in the same or similar specialty in the same geographical area, as reported in a benchmarking database — FAIR Health), training and experience of the provider, complexity of the service, severity of the patient’s condition, and other factors. Unlike federal IDR’s QPA-anchored approach, the NY standard centers on usual-and-customary data.
Determination. The IDRE issues a binding determination, generally within 30 days of receipt. The losing party pays the IDRE fee. Split decisions split the fee.
Patient hold harmless. Under FSL § 606, a non-participating provider may not bill an insured for a surprise bill or out-of-network emergency services beyond the in-network cost-sharing amount. The provider’s recourse for the balance is the IDR process and direct negotiation with the issuer — not the patient.
Surprise Bill Assignment of Benefits (AOB). For surprise bill matters, the insured must sign an AOB form permitting the provider to seek payment from the issuer through the IDR process.
What the Firm Handles in IDR Matters
Eligibility analysis. Plan type determination, specified state law applicability, item and service type qualification under federal or NY IDR, and identification of the correct forum. This is the most consequential step.
Open negotiation. Drafting and serving open negotiation notices, preparing the negotiation position, and pursuing pre-IDR resolution where the economics favor it.
IDR initiation. Preparation and timely filing of the Notice of IDR Initiation through the Federal IDR Portal or DFS submission, with supporting documentation, eligibility attestations, and proper plan-type identification.
IDR entity selection and challenge. Joint or random selection in federal IDR; conflict-of-interest review; eligibility objections from the non-initiating party.
Offer strategy and submission. Quantitative analysis of QPA, FAIR Health data, market rates, and case-specific factors. Drafting the supporting submission. Baseball-style arbitration rewards offers grounded in defensible data — high-anchored offers without supporting evidence regularly lose.
Batching strategy. Identifying batch-eligible claims; structuring batches to minimize per-dispute fees; avoiding cooling-off and re-filing problems.
Recurring payer disputes. Practices with persistent underpayment patterns from a particular payer benefit from a programmatic IDR strategy rather than ad hoc filings. The firm can build the workflow.
Compliance posture. Patient hold-harmless compliance, AOB administration, surprise billing notice and disclosure obligations, good-faith estimates for self-pay patients, and documentation discipline that protects future IDR positions.
Frequently Asked Questions
My EOB shows a payment well below the billed amount. Should I file IDR?
Maybe. IDR has filing fees, time costs, and a 90-day cooling-off rule. The threshold question is whether the dispute is IDR-eligible at all (plan type, service type), and whether the expected recovery justifies the cost. The firm runs that analysis as part of intake.
Do I have to do open negotiation first?
For federal IDR, yes — the 30-business-day open negotiation period is a statutory prerequisite. Skipping it forfeits the IDR option. NY IDR has its own procedural prerequisites under 23 NYCRR Part 400; the framework is different but a parallel exhaustion concept applies.
How do I know if a plan is ERISA self-funded or fully insured?
Self-funded plans typically administer through a TPA (often a major commercial insurer acting as administrator only); the EOB and member ID card may indicate “administered by” rather than “insured by.” Plan documents and SBC disclosures confirm the structure. The non-initiating party in federal IDR must attest to the plan type, but providers should diligence this before initiating.
What is the QPA and how is it calculated?
The Qualifying Payment Amount is generally the plan’s median in-network rate for the same or similar service in the geographic region as of January 31, 2019, indexed forward for inflation. QPA serves as an anchor in federal IDR — the IDRE considers QPA along with statutory factors. Note that the calculation methodology has been subject to litigation (the TMA III line of cases struck down significant portions); the regulatory landscape continues to evolve.
Can I batch claims to lower the per-dispute cost?
Yes, but the eligibility rules are strict: same payer, related service codes, narrow time window, and other regulatory requirements. Improper batching gets the entire batch dismissed and may trigger cooling-off restrictions. Get the batching analysis right before filing.
Can I bill the patient for the balance?
For NSA-protected services and NY surprise bills: no. The patient’s responsibility is limited to the in-network cost-sharing amount. The provider’s recourse for the balance is the payer, through IDR or direct negotiation. Balance-billing a patient on a protected claim creates separate liability under federal and state law.
What happens if I lose IDR?
The plan’s offer prevails as the out-of-network rate for that claim. The losing party pays the IDR entity fee. The 90-day federal cooling-off rule prevents re-filing the same item or service against the same payer. Strategically, repeated losses against a particular payer warrant rethinking the offer construction, the supporting evidence, or the entity selection — not just re-filing.
