No Surprises Act & State IDR Guides
Hawaii No Surprises Act & IDR Guide
Hawaii does not operate an independent state-level arbitration forum or specified state law for commercial out-of-network surprise medical billing. Under HRS Chapter 431, out-of-network dispute resolution for emergency services, post-stabilization care, non-emergency services at in-network facilities, and air ambulance transports in Hawaii defaults directly to the Federal No Surprises Act (45 CFR § 149.510) Independent Dispute Resolution (IDR) process administered by CMS.
Plain-language overview
Direct Federal Jurisdiction: Out-of-network balance billing disputes in Hawaii fall under the Federal No Surprises Act IDR process via CMS.
Hawaii does not operate an independent state-level arbitration forum or specified state law for commercial out-of-network surprise medical billing. Under HRS Chapter 431, out-of-network dispute resolution for emergency services, post-stabilization care, non-emergency services at in-network facilities, and air ambulance transports in Hawaii defaults directly to the Federal No Surprises Act (45 CFR § 149.510) Independent Dispute Resolution (IDR) process administered by CMS.
Start with plan jurisdiction, not the provider's location alone. Fully insured coverage may be governed by a specified state process, while self-funded employer plans commonly remain in the Federal Independent Dispute Resolution process. Confirm eligibility from the remittance, plan information, applicable state law, and current federal guidance before opening a dispute.
Which process applies in Hawaii?
Federal No Surprises Act Fallback
Because Hawaii has not enacted an alternative specified state dispute mechanism approved under 45 CFR § 149.30, both state-regulated commercial plans under HRS Chapter 431 and federally regulated self-funded ERISA group health plans are adjudicated through the Federal IDR process.
ERISA And Commercial Scope
All comprehensive commercial coverage types in Hawaii—including individual market policies, small and large group employer plans, and self-insured health plans—utilize standard federal open negotiation and certified IDR entities.
Air Ambulance Scope
Air ambulance payment disputes arising in Hawaii are governed exclusively under federal No Surprises Act statutory standards and must be initiated through the federal IDR portal.
Open negotiation requirements
Federal Process
Providers and facilities in Hawaii must submit a compliant Open Negotiation Notice (CMS-10779) to the payer within 30 business days of receiving an initial payment or notice of denial. The parties must complete a mandatory 30-business-day open negotiation period before federal arbitration can be initiated.
State Process
Not applicable. Hawaii does not maintain an independent state-level conciliation or mediation process under HRS Chapter 431 for commercial balance billing disputes.
Federal and state IDR procedure
Federal Dispute Forum
Disputes arising in Hawaii are initiated through the CMS Federal IDR Portal (nsa-idr.cms.gov). CMS assigns an approved Certified Independent Dispute Resolution Entity (CIDRE) to arbitrate the dispute.
Baseball Style Arbitration
Under federal law, the certified IDR entity conducts final-offer ("baseball-style") arbitration. The IDR entity evaluates the Qualifying Payment Amount (QPA), provider qualifications, patient acuity, facility market share, and demonstrative evidence to select either the provider or the payer final offer without compromise.
State Dispute Forum
No separate state dispute forum is maintained in Hawaii; Hawaii Insurance Division (DCCA) oversees insurer licensing under HRS Chapter 431 and coordinates with CMS for provider-payer payment disputes.
