4.125—Diagnosis of mental disorders.
(a)
If the diagnosis of a mental disorder does not conform to DSM-IV or is not supported by the findings on the examination report, the rating agency shall return the report to the examiner to substantiate the diagnosis.
(b)
If the diagnosis of a mental disorder is changed, the rating agency shall determine whether the new diagnosis represents progression of the prior diagnosis, correction of an error in the prior diagnosis, or development of a new and separate condition. If it is not clear from the available records what the change of diagnosis represents, the rating agency shall return the report to the examiner for a determination.
