A medical device system comprising: an implantable medical device comprising: at least one storage element; an electronic prescription indicator configured to indicate whether the implantable medical device is authorized for a medical procedure that includes a disruptive energy field, wherein the electronic prescription indicator includes one or more designated bits within the at least one storage element of the implantable medical device; an electronic prescription that defines one or more device operating parameters of an exposure operating mode for use in the disruptive energy field, wherein the electronic prescription is stored within the at least one storage element of the implantable medical device; a transceiver configured to transmit and receive communications; and a processor configured to control operation of the implantable medical device, a first external device that communicates with the implantable medical device to cause the processor to configure the electronic prescription indicator to indicate that the implantable medical device is authorized for the medical procedure that includes the disruptive energy field; and a second external device that communicates with the implantable medical device to confirm that the electronic prescription indicator of the implantable medical device is configured and invoke the electronic prescription upon confirming that the electronic prescription indicator is configured; and wherein the processor is configured to configure the electronic prescription indicator to indicate that the implantable medical device is configured with the electronic prescription and is configured to cause the transceiver to transmit a communication that includes a value of the electronic prescription indicator in response to a communication from the second external device. an implantable medical device comprising: at least one storage element;
