need to bring the 30 days readmit logic as single line

This may do it, but I'm not sure that your input data matches your expected results. (e.g. why do you have to lines for member 1? There's only one data row for that member in your input data that I can see.)

select Membno, clientlname, clientfname, svccod, h1.admitdat, h1.dischrgdat, h2.admitdat, h2.dischrgdat
from @Hosptial h1
outer apply
(
select h2.admitdat, h2.dischrgdat
from @Hosptial h2
where h1.Membno = h2.Membno
and h1.admitdat <> h2.admitdat
and 30 >= abs(datediff(day, h1.admitdat, h2.admitdat))
) h2

but the reverse data also comes from your output for the member 1 and 5

member 1 discharged at '2016-11-09' and Readmit after 30 days is '2016-12-02 00:00:00.000' which is correct in your query. but for the same member line item:2
discharged as '2016-12-07 00:00:00.000' and readmit after 30 days takes '2016-11-03 00:00:00.000' it should be null.
