Haha, you're funny. If its cold storage it wont be a chip. And there is no way what the "doctor" would know what it is. There is no way you should rely on a chip for storing millions of dollars.
Either its cold storage and its not a chip or its a chip for accessing it often (not cold storage).
Not its not funny, there are many shady doctors out there that would do this. If people would start putting chips under their skins, storing digital money (not necessarly bitcoin but even bank account passwords), many mobsters would be interested in obtaining a list of these clients and then "visiting them" and then "extracting them".

It is not as secure as you think.
I do not think you are understanding what i'm saying. I will clarify;
You can use a chip. Sure a rfid chip could work as part of a hardware wallet thing, not on its own because anyone can read the passive reading on the chip, for a spending wallet in your everyday usage OR you can seal in a sealed capsule, the size of a grain of rice, an encrypted hash, that no one knows whats on it. Not the doctor, not anyone.
Its totally hardcore, and i would not to it, but, unless you have made it known that you own millions of dollars in BTC' in which case it does not matter where you hide it, criminal could extort you, its just as secure as hiding it in your socks. Or more
