Surprise bills and ambulance bills in Connecticut

What it adds

If an out-of-network provider treats you at an in-network facility (during a procedure by an in-network provider or one your insurer approved) and you did not knowingly choose that provider, or an out-of-network lab gets your test from an in-network provider's referral, you pay only your in-network cost sharing. Emergency care needs no prior approval and costs no more than in-network cost sharing. The same applies to children's urgent crisis center services.

Itemized bills and price estimates in Connecticut

Connecticut law gives you a right to an itemized bill within 30 days.

If you are a self-pay patient, a hospital must give you an itemized bill within 30 days after you ask. It must list in plain language each service, supply or medication and its charge. Hospital admission forms must tell self-pay patients they can get a copy of their charges and whom to contact. All hospital bills must explain any codes or initials and show the hospital's cost-to-charge ratio.
