Out-of-network claims are where most anesthesia groups either recover real money or quietly lose it — and Texas is uniquely complicated because two different surprise-billing systems apply depending on the patient's plan. Sending a claim down the wrong path means it bounces while the deadline runs. Here's how to tell which law applies, where the disputes go, what the current legal landscape looks like in 2026, and how to actually recover more. (Choosing a partner to run this? See our guide to choosing an anesthesia billing company in Texas.)
Why Anesthesia Is So Often Out-of-Network
Patients choose their surgeon and facility; they almost never choose their anesthesiologist — the surgical schedule assigns one. That means anesthesia groups routinely treat patients whose plans they aren't contracted with, generating high out-of-network volume by default. It's exactly this dynamic that surprise-billing laws were written to address, which is why anesthesia sits at the center of both the Texas and federal frameworks.
SB 1264: The Texas State Track
Texas Senate Bill 1264, effective since January 2020, protects patients in state-regulated plans from balance billing in emergencies and when they had no choice of provider — which explicitly includes an anesthesiologist assigned to a surgery. You can spot these plans because their ID cards are marked "TDI" or "DOI," and the category also covers Employees Retirement System (ERS / HealthSelect) and Teacher Retirement System (TRS) coverage. When SB 1264 applies, the patient is removed from the middle and payment disputes go through Texas Department of Insurance arbitration.
The No Surprises Act: The Federal Track
Self-funded and ERISA employer plans — which cover most large-employer enrollees — are not governed by SB 1264. They fall under the federal No Surprises Act, which prohibits balance billing in the same situations and resolves payment disputes through federal Independent Dispute Resolution (IDR). Federal IDR centers on the Qualified Payment Amount (QPA) — an insurer-calculated median contracted rate. Crucially, the QPA is a benchmark, not a cap.
| Patient's plan | Law that applies | Dispute process |
|---|---|---|
| State-regulated (TDI/DOI card, ERS, TRS) | Texas SB 1264 | TDI arbitration |
| Self-funded / ERISA employer plan | Federal No Surprises Act | Federal IDR (QPA-based) |
| Medicare / Medicaid | Program rules | Program appeals |
Where the Federal Rules Stand in 2026
The federal framework has been heavily litigated, much of it driven by the Texas Medical Association's lawsuits in the Fifth Circuit — which generally favored providers by pushing back on rules that told arbitrators to lean on the insurer-set QPA. As of mid-2026, three things matter for anesthesia groups:
The QPA isn't a ceiling. Arbitrators must weigh the QPA alongside other factors — complexity, training, acuity, market rates — so a well-documented claim can and should beat the QPA. The QPA methodology is unsettled. The Fifth Circuit granted en banc rehearing on the QPA calculation rules and vacated the prior panel opinion; the issue remains pending, and federal enforcement discretion lets plans keep using the existing methodology in the interim. There's no private right of action to enforce IDR awards. The Fifth Circuit held that providers can't sue in court simply to confirm an IDR award, which makes getting the IDR submission right the first time even more important. Because this area is actively changing, work from current guidance rather than last year's rules.
How to Recover More on Out-of-Network Anesthesia
Whether a claim runs through SB 1264 arbitration or federal IDR, the winning playbook is the same: don't accept the opening offer, and build a documented case. Benchmark every out-of-network claim against UCR and Fair Health data, use the open-negotiation period, and escalate to arbitration or IDR with evidence of procedure complexity and fair market value. Vendor repricing through Zelis, Multiplan, and Viant is an opening position, not a final number — our non-contracted solutions and out-of-network billing teams challenge each one.

One Rule That Never Changes: Don't Balance Bill the Patient
When either law applies — and for an assigned anesthesiologist, one almost always does — billing the patient for the balance is prohibited. The recovery comes from the health plan, through arbitration or IDR. Pursuing the patient instead isn't just a dead end; it creates compliance exposure. The right move is to route the underpayment to the correct process and make the documented case for fair value.
