Insurance Denied at a Children's Hospital? How to Fight Back

Children's hospitals occupy a unique and often painful position in the American healthcare system. They provide specialized, life-saving care that no general hospital can replicate — yet they are frequently out-of-network for commercial insurance plans, leaving families facing bills in the tens of thousands of dollars for care their children cannot receive anywhere else.

If your insurer denied or significantly underpaid a claim for care at a children's hospital, this guide explains the legal framework that protects your family and how to mount an effective appeal.

Why Children's Hospitals Are So Often Out-of-Network

There are 220 children's hospitals in the United States, including 46 freestanding children's hospitals that exclusively serve pediatric patients. These hospitals are expensive to operate. They maintain specialized equipment, employ highly trained pediatric subspecialists, and serve a patient population with complex, high-acuity conditions that require longer stays and more intensive resources.

Commercial insurance plans negotiate rates with hospital systems, and freestanding children's hospitals often cannot accept the same rates as large general hospital systems. When the contracts fail, children's hospitals end up out-of-network, and families are caught in the middle.

The No Surprises Act: Your First Line of Protection

The No Surprises Act, which took effect in January 2022, provides critical protections for emergency care at out-of-network facilities. If your child received emergency care at an out-of-network children's hospital, here is what the law requires:

• You cannot be billed more than the in-network cost-sharing amount (deductible, copay, or coinsurance) that would apply if the care were provided in-network
• The insurer must pay the out-of-network provider directly
• Balance billing — the practice of billing patients for the difference between the provider's charges and what insurance pays — is prohibited for emergency services

If you received a bill for amounts beyond your in-network cost-sharing after emergency care at an out-of-network children's hospital, that bill may be illegal under the No Surprises Act. Contact your insurer and file a complaint with the Centers for Medicare and Medicaid Services.

Non-Emergency Care: The Network Adequacy Argument

The No Surprises Act's protections are narrower for non-emergency care. If your child received planned, non-emergency care at an out-of-network children's hospital, you face a harder fight — but not an impossible one.

The ACA requires that health plans maintain adequate networks of providers, including pediatric specialists. Federal regulations at 45 C.F.R. § 156.230 set network adequacy standards for Marketplace plans, and most state insurance departments have adopted similar standards for fully insured commercial plans.

A network adequacy argument works like this: if no in-network facility offers the same pediatric subspecialty service your child required — pediatric cardiac surgery, pediatric bone marrow transplant, pediatric neurosurgery — then the plan's network is legally deficient for that service. In that case, the insurer should be required to provide access to the needed service at in-network cost-sharing rates, even if that requires going out-of-network.

To build this argument, document:

• The specific service or subspecialty your child required
• The geographic radius of in-network providers and whether any offer the specific pediatric service
• Any communications from in-network facilities indicating they could not provide the needed level of pediatric subspecialty care
• A letter from your child's physician explaining why the children's hospital was medically necessary

ACA Pediatric Care Requirements

The Affordable Care Act established pediatric services as one of the ten Essential Health Benefits. ACA-compliant plans must cover pediatric services, but "pediatric services" under the ACA specifically includes pediatric oral health services and pediatric vision services in addition to standard medical coverage.

More broadly, the ACA's prohibition on preexisting condition exclusions and its network adequacy requirements together create a legal framework that supports arguments for access to children's hospitals. When an insurer's network lacks pediatric subspecialty coverage, the ACA's access-to-care mandate provides a basis for challenging that gap.

Single-Case Agreements

When a child's care genuinely cannot be provided at an in-network facility, insurers can enter into single-case agreements (SCAs) with out-of-network providers. An SCA is a one-time contract under which the insurer agrees to pay the out-of-network children's hospital at an agreed rate, and the family pays only their in-network cost-sharing.

To request an SCA, contact your insurer's case management or provider relations department before the procedure if possible. Your child's physician and the children's hospital's patient financial services team can often assist with this request. While insurers are not universally required to grant SCAs, the combination of network inadequacy documentation and a physician's medical necessity letter makes a compelling case.

Filing a State Insurance Complaint

If your insurer refuses to negotiate an SCA or denies that its network is inadequate, file a formal complaint with your state insurance commissioner. Network adequacy complaints receive regulatory attention, particularly when they involve pediatric care.

State insurance commissioners can compel insurers to provide access to necessary care at in-network cost-sharing, issue fines for network inadequacy violations, and require corrective action plans.

Fight Back With ClaimBack

Being denied coverage at the only facility that could care for your child is one of the most unjust outcomes in the health insurance system. ClaimBack helps families craft network adequacy arguments, No Surprises Act complaints, and full appeal letters that give children's hospital claims the best possible chance of payment.
