you can group case should work.

select case when d.diagnosis_code <5 '<5' else '>5' end,        c.sex,        count(*) customers c join diagnosis d   on c.pid=d.pid d.diagnosis_code<>5   , month(d.date_done)=3 group case when d.diagnosis_code <5 '<5' else '>5' end,          c.sex;

sqlfiddle (note 2 rows added diagnosis table).
