Short answerAnesthesia is a core specialty covered by the No Surprises Act: patients usually can't choose their anesthesiologist, so out-of-network anesthesia at in-network facilities can't be balance billed for most patients, and the notice-and-consent exception doesn't apply. Groups contest low payments through open negotiation and federal IDR.
Anesthesia groups felt the No Surprises Act more than most specialties, because so much of their work happens at facilities they don't control.
Why anesthesia is different
- patients rarely choose their anesthesia provider
- anesthesia is one of the ancillary services where out-of-network providers can't use the notice-and-consent exception to balance bill
- payment is formula-based, so a low conversion factor repeats on every case
What groups should track
| Item | Why |
|---|---|
| Network status at each facility | Determines whether NSA rules apply |
| Out-of-network payments by plan | Starts the 30-business-day negotiation clock |
| Units and conversion factor paid | Basis for the dispute |
| Plan type (self-funded vs fully insured) | Federal vs state process |
The dispute path
- initial payment, often near the QPA
- open negotiation within 30 business days
- federal IDR within 4 business days after negotiation ends
- offers with evidence: training, acuity, case mix, prior rates
