In any case in which medical questions arise with respect to the
appropriate diagnosis, extent, effect of, appropriate treatment, and the
duration of any such care or treatment, for an injury covered by the
Act, the Director, OWCP, through the district directors having
jurisdiction, shall have the power to evaluate such questions by
appointing one or more especially qualified physicians to examine the
employee, or in the case of death to make such inquiry as may be
appropriate to the facts and circumstances of the case. The physician or
physicians, including appropriate consultants, should report their
findings with respect to the questions raised as expeditiously as
possible. Upon receipt of such report, action appropriate therewith
shall be taken.
