Out-of-network balance billing disputes operate under a strict jurisdictional bifurcated model: state-regulated fully insured plans, municipal plans, and participating entities utilize the HSCRC Rate Structure for Hospitals; MIA for HMO Providers, whereas self-funded ERISA employer plans and air ambulance disputes fall under the Federal No Surprises Act (45 CFR § 149.510) Independent Dispute Resolution (IDR) portal.
Plain-language overview
Bifurcated: State-regulated plans follow Maryland surprise medical billing arbitration under Md. Code Ann., Health-Gen. § 19-219 & Ins. § 19-710; ERISA self-funded and air ambulance claims proceed under Federal IDR.

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 Maryland?
State Regulated Coverage
Fully insured commercial group, individual, and state-governed health plans in Maryland fall under Md. Code Ann., Health-Gen. § 19-219 & Ins. § 19-710 administered by the Maryland Health Services Cost Review Commission & MIA. Review the member card and payer remittance to confirm state-level jurisdiction before opening an action.
Self Funded Coverage
Self-funded employer group health benefit plans governed exclusively by ERISA are exempt from Maryland state dispute mandates and proceed directly to the Federal No Surprises Act IDR mechanism, unless the plan sponsor has made an affirmative statutory opt-in under applicable state rules.
Air Ambulance And Federal Scope
Air ambulance claims and disputes involving out-of-state non-qualifying plans in Maryland fall exclusively under Federal IDR jurisdiction under 45 CFR Part 149.
Open negotiation requirements

Code Ann., Health-Gen. § 19-219 & Ins. § 19-710, parties in Maryland may engage in state-mandated informal dispute negotiation or direct payment conciliation before filing with the HSCRC Rate Structure for Hospitals; MIA for HMO Providers.
