A Visual Guide for Outpatient Imaging

The No Surprises Act

Federal patient protections against unexpected out-of-network medical bills — and what they mean in practice for imaging centers.

Jan 2022 Effective Date
3 Protected Scenarios
2 Compliance Axes
The Big Picture

Two parts. One law.

For providers, the No Surprises Act operates along two distinct axes. Both apply to outpatient imaging centers — and both create operational obligations.

01

Balance-Billing Restrictions

When the Act applies, out-of-network providers cannot bill patients beyond the protected in-network cost-sharing amount. Imaging is a protected ancillary specialty.

For insured patients
02

Good Faith Estimates

Providers must give written estimates of expected charges to uninsured or self-pay patients for scheduled services, or upon request — and retain them for six years.

For uninsured / self-pay patients
When patients are protected

Three protected scenarios.

The Act protects insured patients in three defined situations — the situations where they had little or no practical ability to choose an in-network provider.

1

Emergency Services

Out-of-network hospitals, freestanding EDs, or emergency clinicians. Patient pays only the in-network cost-sharing amount.

2

Non-Emergency Ancillary at In-Network Facilities

Includes radiology, anesthesiology, pathology, neonatology, and similar hospital-based specialties. Waivers generally not permitted.

3

Air Ambulance Services

Out-of-network air ambulance transport is federally protected. Ground ambulance is generally not covered the same way.

Protected ancillary specialties

Imaging is on the list.

Hospital-based specialties most often associated with surprise billing — and most often protected by the Act.

Radiology

Imaging interpretation

Anesthesiology

Surgical / procedural

Pathology

Biopsy / lab

Emergency Medicine

ED physicians

Neonatology

NICU coverage

Assistant Surgery

Surgical support

Hospitalist

Inpatient medicine

Intensivist

ICU / critical care
What patients pay

In-network rates. Even when the provider isn’t.

When the Act applies, patient cost-sharing cannot exceed what they would have paid at an in-network provider. The protected amount counts toward their in-network deductible and out-of-pocket maximum.

Before NSA

Good Faith Estimates

Four steps. Self-pay patients only.

The GFE process is separate from insurance billing. It applies to patients who are uninsured, or who have insurance but choose not to use it.

Step 1
Identify the patient

At scheduling, flag uninsured or self-pay status.

Step 2
Build the estimate

Include modality, contrast, professional interpretation, and other expected charges.

Step 3
Deliver in writing

Provide the GFE for scheduled services, or upon request.

Step 4
Retain six years

Maintain in the medical record; available upon request.

$400
Dispute Threshold
The $400 rule.

If an uninsured or self-pay patient receives a final bill at least $400 more than the Good Faith Estimate from a provider or facility, the patient may use the federal patient-provider dispute resolution (PPDR) process. This is why GFEs must be specific, documented, and retained.

Scope and limits

What the Act does — and doesn’t do.

The NSA is targeted. It is not a universal protection against every unexpected medical bill.

What the NSA DOES

  • Limits patient cost-sharing to in-network levels in protected scenarios.
  • Bans balance billing for emergency care and most ancillary hospital-based services.
  • Requires Good Faith Estimates for uninsured and self-pay patients.
  • Provides a federal dispute pathway when bills exceed the GFE by $400+.
  • Counts protected cost-sharing toward in-network deductible and OOP max.

What the NSA DOES NOT Do

  • Eliminate deductibles, coinsurance, or copays.
  • Require insurance companies to pay every claim submitted.
  • Convert all out-of-network care into in-network care.
  • Apply to every unexpected or high medical bill.
  • Preempt state laws or payer contracts that add requirements.

A critical distinction

The NSA does not prevent collecting patient responsibility after adjudication when properly owed. It does not require accepting an estimated pre-service amount as final. But it does create real legal and financial risk if a protected patient is balance billed in a covered scenario, or if a self-pay patient is not given a proper GFE.

Operational implications

Seven things imaging centers must do.

Compliance touches scheduling, eligibility verification, registration, financial counseling, billing, and records retention. Here’s the operational checklist.

1
Avoid improper balance billing when the NSA applies

Flag OON claims in protected scenarios and route to compliance review before patient billing.

2
Provide Good Faith Estimates to uninsured and self-pay patients

Standardize a GFE template by modality (MRI, CT, and other services offered) — generate at scheduling.

3
Distinguish estimates from final insured responsibility

Dual-disclosure script: insured estimates marked “pending payer adjudication,” self-pay get a formal GFE.

4
Verify in-network status with the patient’s plan

Run eligibility and benefits at scheduling. Document network status; trigger NSA workflow if OON.

5
Communicate that insured responsibility finalizes post-adjudication

Include EOB-dependent language on all pre-service estimates and patient statements.

6
Maintain documentation for six years

Retain GFEs in the medical record. Archive notice-and-consent forms indexed by encounter.

7
Use compliant notice and consent language where applicable

Use CMS-issued standard forms. Confirm the modality is not on the protected ancillary list before requesting a waiver.

The Bottom Line

Tell patients clearly whether the service is in-network, out-of-network, self-pay, or insurance-billed. Provide Good Faith Estimates when required. Avoid balance billing in protected situations. And wait for payer adjudication before representing an insured patient’s final responsibility as definitive.
