(1) The health care provider may require payment at or before the time services are rendered of any deductibles and co-payments required by the patient's health insurance plan.
(2) The health care provider shall file a claim with the insurer directly for any amounts in excess of the deductible and co-payment which the patient is responsible.
(3) Notwithstanding the provisions of this section, if a patient has not met his deductible under the plan, the health care provider may require payment for service rendered in sums up to but not exceeding the amount of the remaining deductible if less than the service being provided, or the fee if less than the deductible.
(b) The patient shall demonstrate current membership in a health insurance plan, and provide evidence that deductibles, if applicable, have been satisfied.
