If a health care provider submits a bill to an enrollee based on cost-sharing for treatment or services provided by the health care provider that is in excess of the normal cost-sharing applied for such treatment or services provided in-network, as prohibited under section 300gg–115(b) of this title, section 1185i(b) of title 29, or section 9820(b) of title 26, as applicable, and the enrollee pays such bill, the provider shall reimburse the enrollee for the full amount paid by the enrollee in excess of the in-network cost-sharing amount for the treatment or services involved, plus interest, at an interest rate determined by the Secretary.
For purposes of this section, the term “provider directory information” includes the names, addresses, specialty, telephone numbers, and digital contact information of individual health care providers, and the names, addresses, telephone numbers, and digital contact information of each medical group, clinic, or facility contracted to participate in any of the networks of the group health plan or health insurance coverage involved.
Nothing in this section shall be construed to preempt any provision of State law relating to health care provider directories.
