What to do about podologists?

I currently want to add a podologist, and I have no idea which tags to use.
After some Research, I am not even sure that this term is clearly delineated from a podiatrist, some info is here - it seems that a podiatrist performs surgery while a podologist doesn't, so I don't know if it's appropriate to put a podologist under healthcare=podiatrist.

Here are a few variants I have seen:

• There is office=podologist which is used quite frequently but tends to be combined with other things such as shop=medical (example) - quite often these nodes also have no healthcare tag at all.
• For healthcare:specialty, there is podiatry, podiatrist and podologist - which makes me wonder which one should be used - I doubt it makes sense to have all three in use
• For healthcare, usually podiatrist is used, but I have sometimes seen doctor as well
• This is the only node in the world with healthcare=podologist
