Unless you get lucky to have a territory with workers comp doctors, you will be at the bottom.
Zynex is not in network with insurance companies and most often, a pt will get denied coverages and your prescribers will get upset with you. Prescribers will want to know if a device is covered and although you know it is not, you have to give them the canned response that "While coverage is not gaxreteed, we work with all insurance plans". SHADY!
Zynex will send devices to a pt prior to knowing if it is covered and pt will pay out of pocket. You have to use your personal cell phone and you will have patients calling you directly and you will have to deal with the lack of coverage. If you have a large medicare and medicaid patient population, you will have those orders count against you instead of helping your metrics.
