Hi Nukecad;
It seems all to be a play on words. Dla claimants moving to PIP reassessment.On PIP will then be reviewed after a period of time.Those not been on Dla and applying for PIP for first time New Claimants.
It would appear regardless of the term used you have to through a very similar process of form filling and then seen by the independent healthcare professional who goes through your form asking questions.Perhaps a review will mean you do not have to fill in a new form but asked questions relating to your old form to determine whether you are better/worse or same condition as last time.Purely speculation on my part.
My cynical side says whatever they bring in will still involved independent healthcare professional.
