note that batchcode is not a macro, but a macro variable! You should try
to make a macro if you need that:

%macro batchcode(nvisit=);
  %do i=1 %to &nvisit;
    %do j=1 %to...
     ...
  %end;
  %end;
%mend;

...
Proc ...
  class xxxx;
  var %batchcode(nvisit=5);
  output out=xx
       mean(%batchcode(nvisit=5) N=;
run;

Don't know if that works. Would be helpful to see error messages!
