Key Connecticut Consumer Protections
Connecticut’s Surprise Billing Law (Public Act 19-117)
Connecticut enacted surprise billing protections under Public Act 19-117 before the federal law. Connecticut’s law prohibits out-of-network providers at in-network facilities from billing patients more than their in-network cost-sharing amount for emergency and certain non-emergency services. The federal No Surprises Act (2022) extended similar protections to ERISA employer plans that Connecticut’s state law could not reach.
Connecticut’s Mandatory Hospital Financial Assistance (Conn. Gen. Stat. § 19a-673)
Connecticut law requires hospitals to have charity care and financial assistance programs. Specifically, Connecticut hospitals must:
- Offer financial assistance to uninsured and underinsured patients based on income
- Provide written notice of financial assistance programs before billing or collection activity
- Screen patients for Medicaid and financial assistance eligibility before referring debts to collections
- Offer interest-free payment plans
Connecticut’s Hospital Billing Transparency Requirements
Connecticut requires hospitals to provide itemized bills upon patient request and to make their charity care policies publicly available. Hospitals must also provide patients with a good-faith cost estimate for planned non-emergency procedures.
Connecticut Unfair Trade Practices Act (CUTPA)
Connecticut’s CUTPA is one of the broadest state consumer protection statutes in the country. It prohibits unfair or deceptive acts or practices in trade or commerce, and it allows private individuals to sue for damages and attorney’s fees. Deceptive medical billing practices may violate CUTPA, giving you a private right of action in addition to regulatory remedies.
Connecticut HUSKY Health (Medicaid)
Connecticut’s Medicaid program — HUSKY Health — covers children, pregnant women, adults, and people with disabilities. HUSKY members cannot be balance billed for covered services. Disputes about HUSKY billing go through the Department of Social Services.

How to Dispute a Medical Bill in Connecticut
Step 1: Request your itemized bill. Connecticut providers must supply a complete, line-by-line itemized bill on request. Use our EOB decoder to review your insurance Explanation of Benefits alongside the bill.
Step 2: Check for violations. Look for balance billing violations under Public Act 19-117, duplicate charges, upcoding, and charges for services not received. See our billing errors guide.
Step 3: Apply for financial assistance. Ask specifically for Connecticut’s charity care or financial hardship application. Connecticut law requires hospitals to provide this before billing you the full amount, and many patients don’t realize they qualify.
Step 4: Contact the Office of the Healthcare Advocate. This is Connecticut’s unique advantage — the OHA provides free assistance to Connecticut residents navigating insurance denials and billing disputes. Call 1-866-466-4446 before spending your own time fighting the insurer alone.
Step 5: Submit a written dispute. Send a formal written dispute by certified mail citing Connecticut PA 19-117 for balance billing or CUTPA for deceptive billing. Use our dispute letter tool.
Step 6: File a complaint with the Connecticut Insurance Department. The CID actively enforces Connecticut’s billing laws and can order refunds and impose penalties.
Connecticut’s Office of the Healthcare Advocate: Your Secret Weapon

- Explaining the appeals and external review process
- Connecting you with other state resources

FAQ
Q: What is Connecticut’s Office of the Healthcare Advocate and how can it help me? A: The OHA is a state government office that provides free advocacy for Connecticut residents dealing with health insurance denials and billing disputes. They can help you understand your rights, contact your insurer on your behalf, and navigate appeals. Call 1-866-466-4446.
Q: Can a Connecticut hospital bill me before offering financial assistance? A: No. Connecticut law requires hospitals to screen patients for financial assistance eligibility and notify them of available programs before billing. If you received a bill without this information, ask the hospital for their charity care application and cite Conn. Gen. Stat. § 19a-673.
Q: Does Connecticut’s surprise billing law cover my employer’s health plan? A: Connecticut PA 19-117 applies to state-regulated plans. If your plan is a self-funded ERISA employer plan, Connecticut state law doesn’t apply — but the federal No Surprises Act does. For ERISA plan disputes, the OHA can still help you navigate the federal process.
Q: Can I sue a Connecticut hospital for deceptive billing under CUTPA? A: Potentially yes. Connecticut’s CUTPA is a broad consumer protection statute that allows private lawsuits for deceptive trade practices. Medical billing fraud or systematic overbilling may qualify. Consult a Connecticut consumer law attorney for case-specific advice.
Q: What is Connecticut’s external review process for denied claims? A: Connecticut has an independent external review process administered through the Insurance Department. If your insurer denies a claim and your internal appeal fails, you can request external review. The reviewer’s decision is binding on the health plan. The OHA can help you navigate this process.
