Does anyone know the website where you can check the status of Medicare claims?

The new IVR says that you can now check claims online and I think he said something like NGSconnect.com, but I can't find that website and none of my searches produced anything, so...does anyone have a clue as to what website it is?|||As a provider, do you have access to the Medicare FISS system? That is how it is done. Contact your intermediary to get set up if you do not have access as of yet. It's the same system you use to get your electronic payment information.|||As a beneficiary? You register at the Medicare website.
