You instead need to throw most the board of directors of the insurance provider and device manufacturer in question into a Faraday cage, lock it, and walk away.
On a more serious note, this is a new world of crazy for me I wasn't aware of. I wonder how difficult it would be to push forged data back to the monitoring agency with physical access to the machine with an independent setup. Then, simply put your actual device in a Faraday cage so you can still use your device as needed, with insurance covering it, without insurance invading your privacy and likely using that data for other unscrupulous purposes as well.
Might we want to consider that medical insurance fraud is in fact a serious concern?
From prior work in the industry, durable medical equipment is one of the most targeted areas for scams.
Relatively high cost, amortized over an extended utilization time.
I'm not particularly surprised that insurance companies (and therefore manufacturers that are supplying them) include such features. It'd be borderline negligent from a financial perspective not to.
