AZ SB1070

Prohibits health insurers from restricting payment methods to health care providers such that credit card payments are the only acceptable method, and requires health insurers to accept tangible checks as a form of payment.

Requires health insurers that initiate or change payments using electronic funds transfer or virtual credit card payments to notify providers of associated fees, advise of available payment methods with clear instructions, and include explanation of benefits with each payment.

Allows health care providers to opt out of a payment method, with that decision remaining in effect until the provider opts back in or a new contract is executed.

Prohibits health insurers from charging fees solely to transmit electronic funds transfer payments to providers unless the provider has consented, though health care provider agents may charge reasonable fees for transaction management, data management, portal services, and other value-added services.

Defines key terms including "electronic funds transfer payment," "health care provider," "health care provider agent," and "health insurer" for purposes of the statute.
