There is no separate PowerShell cmdlet to keep track of hidden mailboxes in Exchange. You must use the Get-mailbox cmdlet along with the suitable filters and parameters to fetch the results expected.
Example of how to use the Get-Mailbox cmdlet to trace hidden mailboxes:
Get-Mailbox -ResultSize Unlimited -Filter {HiddenFromAddressListsEnabled -eq $True}
Using this cmdlet along with the HiddenFromAddressListsEnabled -eq $True filter, you can get access to the list of all hidden mailboxes in your Exchange organization.
