  Same service billed more than once on a single visit.

  A "facility fee" that exceeds the published standard charge for the service.

Find Cook Children's Medical Center's price file

Since January 2021, federal regulation 42 CFR § 180 requires every US hospital to publish a machine-readable file of standard charges for all items and services. Cook Children's Medical Center maintains this file — it is typically linked from the hospital's billing or “Price Transparency” page. You have the right under § 180.60 to a plain-language summary upon request.

If a line item on your Cook Children's Medical Center bill exceeds the published standard charge, that is the single strongest dispute point under the transparency rule — the hospital cannot charge above its own published rate without producing a documented exception.
