Systems, apparatus, methods and computer-readable storage media facilitating telemetry overuse reduction in an implantable medical device (“IMD”) are provided. In one embodiment, an IMD includes a housing configured to be implanted at least partially within a patient, a memory and circuitry within the housing and a processor that executes executable components stored in the memory. The executable components include: a communication component configured to establish a telemetry connection with an external device to communicate data associated with sensed physiological data or therapy; and an authorization component configured to determine whether the external device is authorized to communicate with the IMD, wherein the communication component is further configured to disable the telemetry connection with the external device and prevent additional communication with the external device for a defined period of time based on a determination that the external device fails to be authorized to communicate with the IMD.
