Answers / Can IONM groups use IDR
Can IONM groups use federal IDR?
Yes. Out-of-network neuromonitoring qualifies for federal IDR when furnished during surgery at an in-network hospital, hospital outpatient department, critical access hospital, or ambulatory surgery center, and during emergency surgery anywhere. IONM is a diagnostic service, so the notice-and-consent waiver mechanism never applies. Remote supervision qualifies on the same terms as in-room monitoring.
The facility connection does the work
IONM eligibility is simpler than most specialties because monitoring only happens in surgery, and surgery happens at statutory facilities. When the hospital or ambulatory surgery center is in-network with the patient's plan and the monitoring group is not, the claim is protected under the No Surprises Act. Emergency and urgent surgeries are protected independently, with no conditions at all. The rare genuinely office-based procedure is the only setting the facility rule leaves out.
Consent paperwork cannot reach monitoring
For some scheduled care, facilities can present a notice-and-consent form that waives protection. The statute forbids that for ancillary services, including diagnostic services, and intraoperative neuromonitoring is a diagnostic service furnished by clinicians the patient never meets while awake. The practical consequence for an IONM company: there is no consent scenario to audit for. If the case was at an in-network facility or was an emergency, the claim is protected, whatever the patient signed at admission.
Remote monitoring counts
Most IONM is delivered as a team: a technologist in the operating room and a supervising professional reading waveforms remotely, billed under 95941. Eligibility follows the patient's site of care, so the remote supervision line qualifies exactly as the in-room lines do. The 2025 record bears this out: 95941 was the second most disputed code in the specialty, with a median decided award of $5,325. Payers sometimes process the remote line as if it were separate from the surgery; the arbitration record treats it as what it is, part of the monitored case.
What falls outside
Medicare, Medicare Advantage, Medicaid, and TRICARE never enter federal IDR; monitoring on those cases is paid under program rules. Self-pay patients are handled through good faith estimates. Cases where the facility itself is out-of-network with the plan fall outside the facility pathway, though emergency surgery remains protected. And state arbitration systems can apply to state-regulated plans; the self-funded employer plans that dominate commercial coverage always route to the federal process.
