Connecticut Surprise Billing Law Highlights
- Covers emergency care, surprise out-of-network providers at in-network facilities, AND certain elective scheduled procedures
- Prohibits balance billing for ALL emergency services regardless of insurance type (broader than NSA)
- Sets default reimbursement at the GREATER of: (a) the median in-network rate, (b) 80% of the usual and customary rate, or (c) the Medicare rate
- Requires hospital-based providers (anesthesiologists, ER docs, etc.) at in-network hospitals to be paid at in-network rates by default
- Allows ground ambulance protection in some cases (CT is one of only a handful of states extending NSA-like rules to ground ambulances)
- Connecticut Insurance Department (CID) handles complaints — no IDR fee for patients
What Is Protected vs Not Protected in 2026
The Ground Ambulance Loophole — The Biggest 2026 Gap
Connecticut
What to Do If You Get a Ground Ambulance Surprise Bill
- Verify whether your plan is fully-insured (CT) or self-funded (ERISA) — check Summary Plan Description
- If CT-regulated, cite PA 22-90 and CGS § 38a-477aa when disputing with the ambulance provider
- Request itemized bill including CPT/HCPCS codes — many ambulance bills contain coding errors
- Ask insurer to apply
- rate calculation rather than allowed amount
- Negotiate directly with the ambulance company — many will accept 30-50% of billed amount
- File complaint with CID if CT plan; file with EBSA (DOL) if ERISA plan
- Request hardship payment plan — most CT ambulance services offer 12-24 month interest-free plans
Good Faith Estimates for Uninsured & Self-Pay Patients
Good Faith Estimate Rules in 2026
- Required for ALL scheduled non-emergency services for uninsured/self-pay patients
- Must include itemized expected charges with CPT/HCPCS codes
- Provided within 1 business day for services scheduled 3-9 days out
- Provided within 3 business days for services scheduled 10+ days out
- Must include charges from all known co-providers (anesthesiologist, pathologist, etc.)

The $400 Rule for Uninsured Patients
Independent Dispute Resolution (IDR) — How It Works for Insured Patients
Federal IDR Process Flow (2026)
- 1. Insurer sends Initial Payment to OON provider within 30 days of receiving clean claim
- 2. Provider has 30 business days to initiate IDR if disputing payment amount
- 3. 30-business-day negotiation period between insurer and provider
- 4. If no agreement, either party initiates IDR through HHS portal (4 business days to file)
- 5. Certified IDR entity reviews
- offers from both sides
- 6. IDR entity selects ONE of the two offers — no compromise — based on Qualifying Payment Amount and other factors
- 7. Decision is binding, must be issued within 30 business days
- 8. Losing party pays the IDR fee ($350-$700 in 2026)

Six Real Connecticut Scenarios
Scenario 1: Sarah, 34, Hartford — ER Visit with OON Doctor
Scenario 2: David, 58, Stamford — Knee Surgery Anesthesiologist
Scenario 3: Maria, 71, Bristol — Ambulance to Emergency Room
Scenario 4: The Patels, New Haven — Uninsured Surgery
Scenario 5: Robert, 45, Greenwich — Air Ambulance from Vacation
Scenario 6: Jennifer, 38, Waterbury — Lab Work Sent to OON Lab
How to Prevent Surprise Bills Before They Happen
Six Defenses Against Surprise Medical Bills
- Verify in-network status by calling BOTH the provider AND your insurer — directories are 35-50% outdated
- For scheduled procedures, request in writing that ALL providers (anesthesiologist, pathologist, etc.) be in-network
- Ask the hospital for a written list of in-network co-providers BEFORE the procedure
- For lab work, specifically request samples be sent to Quest or LabCorp (usually in-network)
- For imaging, ask whether the radiologist reading the scan is in-network (often different from facility)
- Carry your insurance card and an in-network hospital list while traveling — refuse OON care when safe
- Sign any NSA Notice & Consent waiver ONLY when you
- t exist

Frequently Asked Questions
Frequently Asked Questions
What is the No Surprises Act and who does it protect?
The No Surprises Act (effective January 1, 2022) protects insured patients from balance billing in three scenarios: (1) emergency services at any hospital, (2) non-emergency services from out-of-network providers at in-network facilities, and (3) air ambulance services. It applies to all group health plans and individual health insurance, including ERISA self-funded plans. Patients pay only their in-network cost-share; insurers and providers settle the rest via Independent Dispute Resolution.
Does Connecticut have its own surprise billing law?
Yes. Connecticut General Statutes § 38a-477aa (enacted 2015, updated by PA 22-90 in 2022) is one of the strongest state surprise billing laws in the country. It applies to fully-insured CT-regulated plans (about 35% of CT insured residents) and provides equal or greater protection than federal NSA. CT law uniquely extends partial protection to ground ambulances, which the federal NSA does not.
Are ground ambulances covered by surprise billing protections?
Not under federal law. Ground ambulance services were excluded from the No Surprises Act after lobbying from local operators. Connecticut PA 22-90 extended partial protection to 911-dispatched emergency transports for CT-regulated plans only. Self-funded ERISA plan members and non-emergency interfacility transports remain unprotected. The median ground ambulance surprise bill is $450-$1,200 nationally.
What should I do if I receive a surprise medical bill in Connecticut?
Do NOT pay immediately. Request an itemized bill with CPT codes. Determine if NSA or CGS § 38a-477aa applies. Send a written dispute letter citing the applicable law. File a complaint with Connecticut Insurance Department at portal.ct.gov/cid (CT plans) or federal No Surprises Help Desk at 1-800-985-3059 (any plan). Contact the Office of the Healthcare Advocate at 1-866-466-4446 for free help.
Can a hospital make me sign a waiver that gives up my NSA protections?
For NON-emergency scheduled services at in-network facilities, providers may ask you to sign an NSA Notice and Consent waiver SURRENDERING your balance billing protections. They must provide the waiver at least 72 hours in advance with cost estimate. NEVER sign this waiver without first confirming in-network alternatives don’t exist. Emergency services CANNOT be subject to this waiver — it’s prohibited.
What is a Good Faith Estimate and when does it apply?
Under the NSA, uninsured and self-pay patients are entitled to a written Good Faith Estimate (GFE) of expected charges before scheduled services. GFE must include CPT codes for all known charges and co-providers. If your final bill exceeds the GFE by $400 or more for any provider, you can file a Patient-Provider Dispute Resolution at cms.gov/nosurprises within 120 days. PPDR decisions favor patients at least in part roughly 60% of the time.
Does the No Surprises Act apply to my self-funded employer health plan?
Yes. The federal NSA applies to ALL group health plans including self-funded ERISA plans, individual market plans, and fully-insured employer plans. However, Connecticut’s stronger state law (CGS § 38a-477aa) applies ONLY to fully-insured CT-regulated plans. Self-funded ERISA plan members get federal NSA protection but not CT law. Check your Summary Plan Description to determine plan type.
What if I had an emergency out of state? Am I protected?
Yes. The NSA applies regardless of geographic location. An emergency room visit in Vermont, Florida, or anywhere in the U.S. is treated as in-network for cost-sharing purposes by your insurer. Air ambulance from out-of-state to home is also protected. Ground ambulance protection depends on state law where service was provided — some states have ground ambulance laws, most do not.
How long do I have to dispute a surprise medical bill?
Federal NSA: file complaint at cms.gov/nosurprises or 1-800-985-3059 — no strict deadline but sooner is better. Patient-Provider Dispute Resolution for uninsured: 120 days from receiving bill. Connecticut CID complaints: 24 months from claim. Office of Healthcare Advocate: no statutory deadline. Most provider collection actions begin at 90-120 days past due, so act within the first 60 days for best outcomes.
Can I be sent to collections for a surprise bill I
Federal NSA prohibits providers from sending bills to collections during the dispute period if you have filed a formal complaint or initiated IDR/PPDR. Connecticut law similarly protects consumers actively disputing under CGS § 38a-477aa. Always document your dispute in writing, send via certified mail, and request acknowledgment. If a provider sends you to collections during a valid dispute, file complaint with the CT Attorney General and the federal CFPB at consumerfinance.gov.
