Doctor cut a vein? It's not working (8)

I believe the answer is:

unactive

I'm a little stuck... Click here to teach me more about this clue!

'not working' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'doctor cut a vein?' is the wordplay.
'doctor' is an anagram indicator.
'cut'+'a'+'vein'='cutavein'
'cutavein' is an anagram of 'UNACTIVE'.

'it's' is the link.

Can you help me to learn more?
