No Surprises Act violation

In-network hospital, out-of-network anesthesiologist bill

Surgery was performed at an in-network hospital, by an in-network surgeon. Weeks later, a separate bill arrives from the anesthesiologist — who, it turns out, doesn’t participate with the insurance plan at all.

Illustrative example built from BillMender's rules engine — not a real patient's bill, and not a claim about any specific hospital.

The bill

Anesthesia services (out-of-network provider)$1,450.00

Possible No Surprises Act violation — out-of-network at in-network facility$1,450.00

The No Surprises Act specifically covers this situation — an out-of-network ancillary provider (anesthesiologist, radiologist, pathologist, ER physician) treating a patient at an in-network facility. The patient can only be charged the in-network cost-sharing amount, no matter what the provider’s own network status is.

Basis: No Surprises Act, 42 U.S.C. § 300gg-111 et seq. (Pub. L. 116-260, Div. BB, Title I).

Why this happens

Hospitals contract with outside physician groups (anesthesia, radiology, pathology) that negotiate their own separate insurance contracts — a patient can do everything right and still get a bill from a provider they never chose and never met.
