No Surprises Act Rules by Specialty
The No Surprises Act doesn't treat every specialty the same way. Two questions decide whether an out-of-network claim is protected, and whether its payment dispute belongs in IDR: can the patient waive their protections, and where was the care delivered?
At a glance
| Specialty | Can the patient consent to out-of-network billing? | Where protections apply |
|---|---|---|
| Emergency Medicine | No | Any emergency department, in network or not |
| Anesthesiology | No — ancillary service | In-network hospital, HOPD, critical access hospital or ASC |
| Radiology | No — ancillary service | In-network facility or emergency; freestanding imaging centers generally not |
| Pathology & Laboratory | No — ancillary service | In-network facility or emergency; office-ordered lab generally not |
| Air Ambulance | Not applicable | All air ambulance transports; ground ambulance not covered |
| Pain Management | Yes, for scheduled care, if strict rules are met | In-network facility; office-based procedures generally not |
| Obstetrics & Gynecology | Yes, for scheduled care, if strict rules are met; never for emergencies | Emergency labor, or in-network hospital, HOPD or ASC; office visits generally not |
| Surgery | Yes, for scheduled care, if strict rules are met; never for emergencies or assistant surgeons | Emergency or on-call surgery, or in-network hospital, HOPD or ASC; office procedures generally not |
"Ancillary services" can't use the consent exception at an in-network facility. Besides anesthesiology, radiology, pathology and emergency medicine, they include neonatology, assistant surgeons, hospitalists, intensivists, and diagnostic services such as laboratory work. HOPD means hospital outpatient department; ASC means ambulatory surgical center.
