Good idea to show what the output should look like. This is first draft to show groupings, you would need to fiddle with the if's to get exactly what you want;

data want;
  set exp (rename=(visitno=v));
  retain visitno tmp;
  by id uv notsorted;
  if first.id then tmp=0;
  if first.uv and uv="" then do;
    tmp=tmp+0.1;
    visitno=v+tmp;
  end;
run;

As I said, fiddle with the if's to get what you want, as you haven't posted example output. I would guess:

data want;
  set exp (rename=(visitno=v));
  retain visitno tmp;
  by id uv notsorted;
  if first.id then tmp=0;
  if first.uv and uv="" then do;
    tmp=tmp+0.1;
    visitno=v+tmp;
  end;
  if first.uv and un ne "" then do;
    tmp=tmp+0.1;
    visitno=v+tmp;
  end;
run;

Assuming i understand what you want:

data exp;
length uv $200;
infile datalines dsd truncover;
input id uv $ visitno;
datalines;
101,,1
101,unsecheduled-20/mar/2018
101,unsecheduled-20/mar/2018
101,unsecheduled-20/mar/2018
101,unsecheduled-20/mar/2018
101,unsecheduled-20/mar/2018
101,unsecheduled-21/mar/2018
101,unsecheduled-21/mar/2018
101,unsecheduled-21/mar/2018
101,unsecheduled-21/mar/2018
101,unsecheduled-21/mar/2018
101,,2
;
run;

data want;
set exp;
by id;
retain _v;
_k=lag(uv);
if first.id then call missing(_v);
if visitno then _v=visitno;
else if missing(lag(uv)) then _v+.1;
else if _k ne uv then  _v+.1;
if missing(visitno) then visitno=_v;
drop _:;
run;
