On this information I can't see a method other than something of the form
gen newid = # if inlist(current_id, <list>) | inlist(other_id1, <list>) | inlist(other_id2, <list>)

I have a dataset of medical providers at the provider-year level.
Each provider has an ID #. If the provider moves to a new location,
they are assigned a new ID #. I have two other variables that
sometimes contain providers' previous or future ID #s. I'm trying to
create a common ID # for each provider so I can track them over time.
For example, I'd like to assign all of the following observations a common ID #:
current_id other_id1 other_id2
406434166 406434127
406434127 406434166 406414087
406414087 406384157
