Limitations on Charges, Billing, and Collections
Oklahoma limits nonprofit hospital charges.

Hospitals may charge patients who qualify for financial assistance no more than the greater of the amount Medicare would pay for the same services or the hospital’s cost of providing the services. A hospital’s disregard of this limitation may be raised as a defense to a collection action initiated by the hospital against a patient for medical debt. Okla. Stat. tit. 63 §1-723.2.
