Anesthesia billing
Out of network anesthesia groups are often paid near the QPA with little explanation. ZanexMed checks every anesthesia payment and takes underpaid claims to Texas arbitration or federal IDR.
Updated October 31, 2026
Anesthesia IDR is the independent dispute resolution process an out of network anesthesia provider uses when a health plan underpays a covered claim. Anesthesia at an in network hospital or surgery center is protected by the No Surprises Act and by Texas law, so the patient cannot be balance billed and the provider cannot use a patient waiver. Instead, the anesthesia group disputes the payment with the plan: through Texas Department of Insurance arbitration for state regulated plans, or through federal IDR for most self funded plans.
Patients rarely choose their anesthesiologist. When the surgeon and the facility are in network but the anesthesia group is not, the plan sets the first payment, and that payment is often based on the qualifying payment amount (QPA).
Anesthesia is priced differently from most services. A claim is built from base units for the procedure, time units for the minutes of care, and a conversion factor in dollars. Under the federal rules, the QPA for anesthesia is calculated on the conversion factor, so a low median conversion factor pulls every claim down at once.
Small differences per case add up fast for a busy group. That is why anesthesia is one of the most disputed specialties in both the Texas and federal IDR systems.
Anesthesiologists are the second largest group of providers using Texas arbitration.
