If, but for this section, medicare benefit would not be payable in respect of a radiation oncology service rendered by or on behalf of a medical practitioner because the service is:
(a) rendered using radiation oncology equipment that is ordinarily located at radiation oncology premises the registration of which has been suspended; or
(b) rendered using radiation oncology equipment that:
(i) when not in use, is ordinarily located at a base for mobile radiation oncology equipment the registration of which is suspended; and
(ii) is not ordinarily located at radiation oncology premises;
medicare benefit becomes payable in respect of the service when the suspension ceases to have effect, provided the suspension does not cease to have effect because the registration is cancelled under section 23DZZX.
