Dear B+W
Greetings
Still not techy so sorry if not linked correctly thank you

Intro from atos site ''
''If we require information from your GP we will contact them, if you provide their details, and we will pay their fees if appropriate.''

I was at GPs yesterday for medical conditions and I referred to PIP (in general not for me specifically though I am concerned) and my concerns: ? Would they GPs write a letter etc
************************************************
and was told by GP''
that (for another patient) yesterday GP recv'd 'Letter (?Form)' from PIP re said patient.

And it was series of can this patient do this that or other?: GP did not go into specifics of what the this and that was on form or letter PIp had sent them : however said that also some things that PIp asked (in the letter form sent to GP) could patient do or condition restrict:? whatever 'task'

GP had to say did not know the answer and said so.
I checked twice with GP that I ahd understood what GP had said correctly and reply was yes.
**************************************
Q Does this sound correct and what is the specific form or letter sent o GPs :
I guess there is a template blank somewhere?
Is there anywhere to view? please

I recall there was something like a eg ned 3 form (not exact term)
when ESA asked Gp I had old copy tossed now and this is query on PIp: and if so form/letter number or reference please

(A slight PS) I am not sure if GP was ref to appeals' GP did not say appeals, however there was not the time to discuss or approp. really to discuss further, as number of med conditions for Doctor to attend to for me.)

Many thanks wise ones and for all help
