PCEHR Certificate

This certificate is not the Medicare signing or encrypting certificate, it is issued for connecting to the PCEHR. Please contact Medicare for assistance if you have not been issued with a PCEHR (NASH) certificate yet.

The file is called Fac_Sign.p12 and should be located on your network or a CD.
