Out-of-Network Health Insurance Disputes in California
Most health insurance plans encourage policyholders to seek treatment from doctors, hospitals, and other providers that participate in the plan’s network. In-network providers have agreed to negotiated reimbursement rates, which generally means lower out-of-pocket costs for patients.
But what happens when you receive care from an out-of-network provider? Can your health insurer simply deny coverage or leave you responsible for the entire bill?
The answer is often more complicated than many people realize. Under California law, there are serious situations in which a health plan must treat out-of-network care much like in-network care. These protections are especially important when patients have little or no choice about where they receive treatment or when an insurer’s provider network is inadequate.
At Gianelli & Morris, we represent policyholders whose health insurance claims have been wrongfully denied or underpaid, including instances that amount to insurance bad faith. Disputes involving out-of-network care frequently arise in bad faith insurance cases, particularly when insurers ignore California’s consumer protection laws or improperly shift financial responsibility onto patients.
Why Staying In Network Is Usually the Best Option
As a general rule, policyholders should seek care from in-network providers whenever reasonably possible. In-network providers have negotiated reimbursement agreements with the insurer, resulting in lower deductibles, lower coinsurance, and protection from balance billing in most situations. The insurer also has established procedures for paying participating providers, making disputes less common.
Out-of-network benefits, by contrast, are often substantially less generous. Depending on the policy, the insurer may reimburse only a percentage of what it considers the “allowed amount” or “usual and customary” charge, leaving the patient responsible for the remaining balance. For this reason, patients should generally view out-of-network care as an exception rather than the rule.
How Out-of-Network Coverage Typically Works
Many PPO plans provide some level of out-of-network coverage, but the financial responsibility is usually much greater. For example, a policy may reimburse 60 percent of the insurer’s allowed amount after the deductible is satisfied. If the provider charges significantly more than the insurer’s allowed amount, the patient may also be responsible for the difference unless California’s prohibition against balance billing applies. As a result, receiving care outside the network can become unexpectedly expensive, even when the insurer pays part of the claim.
Fortunately, California law recognizes that patients should not always bear these additional costs.
When California Law Requires Out-of-Network Care to Be Treated Like In-Network Care
Several important exceptions require health plans to provide greater protection for policyholders.
Emergency Medical Services
One of the strongest protections applies to emergency care. If you experience a true medical emergency, you generally cannot be expected to determine whether the nearest emergency room or emergency physician participates in your insurer’s network. California law prohibits health plans from imposing greater cost-sharing simply because emergency services were provided by an out-of-network emergency provider. Likewise, emergency providers generally may not balance bill patients for covered emergency services regulated under California law. This protection allows patients to seek emergency care based on medical need, not insurance network status.
Care at an In-Network Facility
Another common situation involves treatment at an in-network hospital or surgery center where one or more treating professionals happen to be outside the insurer’s network. For example, you may carefully choose an in-network hospital only to discover later that the anesthesiologist, radiologist, pathologist, or assistant surgeon was not contracted with your health plan. California’s consumer protection laws generally prevent patients from being caught in the middle of these billing disputes. Instead of treating the care as fully out of network, the law requires the dispute over reimbursement to be resolved between the health plan and the provider, not by billing the patient for the difference.
When the Health Plan Lacks an Adequate Network
California’s network adequacy laws require health plans to maintain sufficient numbers of physicians and specialists so members can obtain medically necessary care within required timeframes. If an insurer cannot provide timely access to an appropriate in-network provider, it may be required to authorize treatment outside the network while limiting the patient’s financial responsibility to what would have applied for in-network care. This situation commonly arises when highly specialized treatment is unavailable within the insurer’s network or when excessive wait times would jeopardize the patient’s health.
California law does more than regulate reimbursement; it also requires health plans to maintain adequate provider networks. If a health plan’s network lacks appropriate specialists or cannot provide appointments within required access standards, the insurer cannot simply tell patients to wait indefinitely or pay out of pocket elsewhere. Instead, the plan may be required to arrange and pay for medically necessary care outside its network. This protection recognizes that insurance coverage has little value if policyholders cannot actually obtain the care promised under their policies.
Common Out-of-Network Disputes
Even with these legal protections, disputes continue to arise. Some insurers deny requests for out-of-network referrals despite the absence of qualified in-network specialists. Others approve treatment but later reimburse only a small portion of the charges. Patients also encounter denials involving emergency care, follow-up treatment, and continuity of care after a provider leaves the network.
Another recurring issue involves insurers characterizing medically necessary referrals as optional patient choices when, in reality, no appropriate in-network alternative existed. When insurers fail to comply with California’s network adequacy requirements or improperly deny authorized care, policyholders may have grounds to challenge the decision.
Examples from California Enforcement and Case Law
California regulators have repeatedly taken action to protect consumers in out-of-network disputes. In 2024, the California Department of Managed Health Care issued statewide guidance reminding health plans that members cannot be balance billed for covered emergency services or for certain non-emergency services provided by out-of-network professionals at in-network facilities. The Department emphasized that billing disputes must be resolved between the health plan and the provider, not the patient.
In another significant enforcement action, the DMHC fined Aetna Health of California after determining that the company repeatedly applied an improper national standard to deny payment for emergency room claims rather than California’s broader legal standard governing emergency services. The Department concluded that members were wrongfully denied coverage and ordered corrective action in addition to imposing a $500,000 penalty.
California courts have also reinforced these protections. In Prospect Medical Group, Inc. v. Northridge Emergency Medical Group (2009) 45 Cal.4th 497, the California Supreme Court held that emergency physicians generally may not balance bill patients covered by Knox-Keene regulated health plans for amounts beyond the patient’s required cost-sharing. The decision reinforced the principle that patients should not become financially responsible because of reimbursement disputes between providers and health plans.
These examples illustrate California’s broader policy objective: protecting patients from bearing the financial consequences of disputes they neither created nor could reasonably avoid.
When an Out-of-Network Dispute May Become Insurance Bad Faith
Not every out-of-network disagreement constitutes bad faith. A legitimate dispute over policy interpretation or reimbursement methodology may involve nothing more than a contractual disagreement. However, bad faith concerns arise when insurers engage in unreasonable claims practices such as:
- Misrepresenting out-of-network benefits or referral rights;
- Ignoring California’s emergency care protections;
- Refusing authorized out-of-network referrals despite network inadequacies;
- Delaying medically necessary treatment without justification; or
- Repeatedly requesting unnecessary documentation to postpone payment.
When these practices cause policyholders to incur unnecessary medical expenses, delay treatment, or suffer other financial harm, additional legal remedies may be available.
Frequently Asked Questions
When must a California health insurer cover out-of-network care as if it were in network?
Generally, this may occur for emergency services, certain care received at in-network facilities from out-of-network providers, or when the health plan lacks an adequate provider network. California law also protects health plan members from being balance billed by ground ambulance providers that are not contracted with their health plan.
Can I be balance billed for emergency medical care in California?
In many situations, no. California law provides strong protections against balance billing for covered emergency services regulated under the Knox-Keene Act.
What if my health plan doesn’t have the specialist I need?
If the plan cannot provide timely access to an appropriate in-network specialist, California law may require it to arrange and cover authorized out-of-network care.
Can my insurer deny an authorized out-of-network referral?
The answer depends on the circumstances. If the referral was properly authorized or required because of network inadequacy, an improper denial may violate California law and, in some cases, support a bad faith claim.
When should I speak with an attorney about an out-of-network dispute?
If your insurer refuses to authorize medically necessary out-of-network care, improperly denies emergency services, or fails to honor California’s consumer protections, it may be appropriate to consult an attorney experienced in insurance bad faith litigation.
