All of these billing tools are free. However, Medicare and other carriers change their LCDs and other policies constantly!!! We will email you when we update these forms. Please sign up for our Email List so we can send you a reminder email when the form is updated. This way, we can ensure that you stay current. We also get requests from providers to add DX and CPT groups to these forms. For instance, we are in the process of adding infrared and diathermy, as well as reasonable and customary limits for modalities; and a modifier usage table.
