Balance Billing, Emergency Care, and a Retroactive Prior Authorization Denial
Marcus, 38, has Crohn's disease and is covered by his employer's self-funded ERISA medical plan, administered by a TPA using a national PPO network. While traveling, he develops severe abdominal pain and goes to an in-network hospital emergency department. The emergency surgeon and the anesthesiologist who treat him are out-of-network. The plan pays the hospital at in-network rates but processes the surgeon and anesthesiologist at out-of-network rates, leaving a $9,000 balance. The TPA also retroactively denies the inpatient admission for lack of prior authorization, which the plan document requires for "non-emergency inpatient admissions." The surgeon has billed Marcus directly and threatened collections.
1. Apply the federal surprise billing protections to the surgeon's and anesthesiologist's bills. Who may bill Marcus, and at what rate?

The plan is covered. The No Surprises Act applies to group health plans, including self-funded ERISA plans, and to non-grandfathered and grandfathered plans alike. It does not apply to Medicare, Medicaid, or excepted benefits.
Emergency services. Care furnished in an emergency department of a hospital, and post-stabilization services, must be treated as in-network regardless of the provider's network status. Cost sharing must be based on the in-network rate, and the patient may be billed only the in-network cost-sharing amount. The surgeon and anesthesiologist cannot balance bill Marcus for the $9,000.
Ancillary services. Even setting emergency status aside, non-emergency ancillary services (anesthesia, radiology, pathology, laboratory, hospitalist) delivered at an in-network facility by an out-of-network provider are protected. The anesthesiologist's bill falls in that bucket on either theory.
Recourse. If the plan and the providers cannot agree on a rate, the dispute goes to the independent dispute resolution process between plan and provider. Marcus is held harmless and should not be sent to collections; a provider who bills him anyway is in violation, and he can file a complaint with CMS or the DOL.
Key distinction: the surgeon's non-emergency professional services at an in-network facility are not automatically protected - but this was emergency surgery, so the emergency-services rule controls.
2. Can the plan retroactively deny the admission for missing prior authorization? Analyze.
Read the worked answer
No, not on these facts - for two independent reasons.
Emergency services cannot be subject to prior authorization under the NSA, and the plan may not deny payment based on a failure to obtain prior authorization for emergency services. The plan's own document limits the requirement to "non-emergency inpatient admissions," and the admission here presented as an emergency - the prudent layperson standard asks whether a reasonable person would have believed delay was dangerous, not whether the final diagnosis proved emergency.
Retrospective review still has to follow claims procedure. Even for genuinely non-emergency admissions, a retroactive denial must be a covered-benefit determination supported by the plan terms and the medical record, issued with a written explanation, and subject to internal appeal and external review. Urgent pre-service requests carry a 72-hour decision deadline and a 24-hour expedited appeal track.
Practical point: the plan cannot use an administrative failure as a coverage determination where the member had no meaningful opportunity to obtain authorization - Marcus presented through the ED.
What the TPA should do: reverse the authorization denial, reprocess the hospital claim and the professional claims at in-network cost sharing, issue a corrected EOB, and notify the providers that balance billing is prohibited.
3. Marcus asks what he should do next and whether his state insurance department can help. Structure the response.

Step 1 - Do not pay the surgeon. Paying can be treated as accepting responsibility. Send the provider a written notice that the claim is subject to the NSA and that balance billing is prohibited, and request that the account be withdrawn from collections.
Step 2 - Appeal inside the plan, in writing. Request the plan document, the adverse benefit determination, and the specific plan provision relied on. File a internal appeal on both issues - the out-of-network cost sharing and the authorization denial - and simultaneously request external review if the internal appeal is denied. The plan's failure to follow its own emergency-services terms is itself an appeal ground.
Step 3 - Regulator: mostly not the state. Because this is a self-funded ERISA plan, the state insurance department generally lacks jurisdiction over the plan's benefit determinations. The right channels are the U.S. Department of Labor Employee Benefits Security Administration for ERISA claims-procedure violations and CMS for No Surprises Act complaints against the providers. His state department of insurance may act against the providers if they are state-licensed and the state has its own balance billing enforcement, but it cannot order the plan to pay.
Step 4 - Keep the paper trail. Every provider communication in writing, and copies of the EOBs, the denial letter, and the bills. If the plan ultimately underpays, Marcus's remedy against the plan runs through ERISA §502(a) and the plan's own review process, not a state bad-faith action.
