Use of prepaid debit cards, prepaid credit cards, gift cards, or any other card not linked with a bank or credit card account from a financial institution is prohibited. As used in this subsection (a), “financial institution” means a state or national bank, a state or federally chartered credit union, or a savings bank.

(b) A healthcare prescriber or facility described in subsection (a) may accept payment for services provided to a patient by the prescriber or facility in cash for a co-pay, coinsurance, or deductible if the prescriber or facility submits the remainder of the bill for the services provided to the patient's insurance plan for reimbursement. If the patient does not have an insurance plan, then the healthcare prescriber or facility shall not accept cash as payment for services provided.

(c) No healthcare provider, licensed by title 63, chapter 6, 7, 9, or 19, shall be compensated or receive payment for services related to buprenorphine treatment:

A person is required to disclose to the healthcare provider or nonresidential office-based opiate treatment facility, as defined in § 33-2-402, that the person is a TennCare enrollee seeking treatment with buprenorphine products for use in recovery or medication-assisted treatment.
