When back from work, call to describe check-up with healthcare worker (4,5)

'when back' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'work call to describe check-up with healthcare worker' is the wordplay.
I cannot quite understand how this works, but
'work' could be 'visit' (visit is a kind of work) and 'visit' is located in the answer.
'call' could be 'ho' (historical exclamation used to attract attention) and 'ho' is located in the answer.
The remaining letters 'me' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'from' is the link.

Can you help me to learn more?
