I was reading a forum on this site regarding what to do when a Schrader valve core breaks ("Broken Valve Core?" is the title), but I am not able to reply to it so I thought I would ask here. A tech let us know that when he was checking the refrigerant pressure, the Schrader valve core wasn't working properly, and when attempting to remove it "the inner part of it has separated itself from the outer part leaving the shell if you want to call it still in the valve", and now says it is a much longer process to remove/replace. I read on the other forum that someone used an EZ-out tool to remove the broken piece, but my question is, with the part stuck in there, how do you block the refrigerant from coming out when the part is removed and then replaced?

I thought when you use the special tool to replace a Schrader core valve, it blocks the refrigerant from exiting...?!? My understanding is Yyou shouldn't have to remove the refrigerant to replace a Schrader core if it is removed properly (or in one piece).

You don't. But the pin is broken and now you need to pull out the gas, cut out and replace the bad valve and recharge

Wrong. The core is broken.
Once it is broken the refrigerant has to be recovered then the valve core may be able to be removed without changing the service valve but best practice would be to replace the service valve or at least have it on hand if removal of the stem is not possible.
There is a way. But you need to get your poat count up and get your pro status so we can tell you how.

His profile identifies him as a homeowner. I don’t think pro status is an option.
