Absolutely not, if the diagnosis is supported by the written medical evidence. The doctor's report is read but it is not challenged. If we need additional justification, we will ask the client to go back to see his doctor for the missing information. As a general rule, a medical report is sufficient. Once the diagnosis has been established and it is clear that it is the right diagnosis, we will not challenge the evidence.
