Radiology sits squarely inside the No Surprises Act’s protections, with one important exception. Radiology is an “ancillary service,” so at an in-network facility the patient can’t be asked to waive their protections — the patient never chose the radiologist. But the protections only apply at certain kinds of facility, and a freestanding imaging center usually isn’t one of them. Knowing which reads are protected is the first step in recovering on them.
Which reads are protected
| Setting | Protected? | Route if underpaid |
|---|---|---|
| Emergency department read | Yes — part of emergency services | Open negotiation → IDR |
| Inpatient or hospital outpatient read, facility in network | Yes — ancillary, no consent waiver | Open negotiation → IDR |
| Ambulatory surgery center, facility in network | Yes | Open negotiation → IDR |
| Scheduled study at a freestanding imaging center | Generally no | Plan appeal; state law may apply |
The Act’s non-emergency protections cover out-of-network providers working at in-network hospitals, hospital outpatient departments, critical access hospitals and ambulatory surgical centers. Freestanding imaging centers aren’t on that list. State surprise-billing laws sometimes reach further, so check the state guides where you practise.
Professional vs. technical component
Most out-of-network radiology disputes involve the professional component — your group’s interpretation of a study performed with the facility’s equipment. Check that each claim was processed with the right component modifier. A professional read paid as if it were global, or a component modifier dropped, is a coding issue for a plan appeal or corrected claim, not an IDR question.
Where radiology underpayments come from
- Payment at or near the QPA on high-volume codes — the core rate dispute, and the one IDR decides.
- Component modifiers misapplied, changing what the plan thinks it’s paying for.
- Multiple-procedure reductions applied to studies that shouldn’t be reduced.
- Facility status errors — a claim processed as if an in-network hospital were out of network.
Sort each one into the right forum before acting. See how to handle out-of-network underpayments.
The economics of disputing reads
A single underpaid read is small. Thousands of them from the same payer are not. That makes radiology a volume game:
- Batch qualifying claims. Federal IDR lets claims from the same provider, paid by the same plan, for the same or similar service be grouped, subject to timing rules.
- Prioritise by payer and code family. Some payers consistently pay well below what IDR awards; those are where batching pays off fastest.
- Watch the clock at scale. The 30-business-day window to start open negotiation runs separately for every claim.
Building the IDR offer
The IDR entity weighs the QPA alongside factors that favour subspecialty radiology: service complexity, training and experience (fellowship training and subspecialty reads), turnaround and coverage commitments, and the parties’ contracting history. It may not consider billed charges or Medicare rates. More on the QPA and what the IDR entity can weigh.
