See link - An important question from Tom Greatrex and very good to know it is under review!!
What Grayling says here is true, but he does not explain that the Atos WCA manual actively discourages HCPs from deviating away from the drop down menus and tick boxes. The reason is that a background algorithm gradually formulates a summary and prognosis that the HCP can then just sign off. Of course the drop-down lists cannot include every condition which is why they often appear simplified on an ESA85 report.
During a WCA, do make sure you expalin your condition fully and in depth - do not give the Atos HCP any excuse to misrepresent or understate.
