I'm seeing sentences using have/has been done, is It Present Perfect? Because Present Perfect is formed [has/have + past participle].

Like:

This has been done in America, but only at practices with a patient-list of 50,000 or more.

There's two past participle.

    It's a present perfect passive construction. The perfect is constructed from a form of HAVE followed by a past participle, the passive is constructed from a form of BE followed past participle, so the perfect passive is a form of HAVE followed by been (the past participle of BE) followed by the past participle of the lexical verb: in this case done as the past participle of do.

It's the equivalent of past pluperfect in a the passive voice.

Try it in the active voice first, and it becomes a little easier to see.

I do it. (present)
I have done it. (past perfect) It is now over and done with.
I had done it. (past pluperfect) Even in the past, it was over and done with.

Back to the passive voice.
It is being done. (present)
It has been done. (equivalent of past perfect)
It had been done (equivalent of past pluperfect)

    Has been done would usually be regarded as present perfect. Had been done would usually be regarded as past perfect. Nov 20, 2015 at 13:59
