After information given on anaesthetic, pay out for medical treatment (4,7)

Ross

I believe the answer is:

gene therapy

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

'medical treatment' is the definition.
(I know that gene therapy is a type of medical treatment)

'after information given on anaesthetic pay out' is the wordplay.
'after information' becomes 'gen' (gen can informally mean information. I am not sure about the 'after' bit.).
'given on' is a charade indicator (letters next to each other).
'anaesthetic' becomes 'ether' (ether is a kind of anaesthetic).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'pay' is an anagram of 'apy'.
'gen'+'ether'+'apy'='GENE THERAPY'

'for' is the link.

Can you help me to learn more?

(Another definition for gene therapy that I've seen is " Treatment applied at cellular level".)

I've seen this clue in The Telegraph.
