Is this what you wanted, I doubt you'd need ORG_ID value twice there..

SET @OrgName = 'SELECT ORG_ID+''' + CONVERT(varchar(10), @orgid) +''' '+ '+[Description]+' + ' ' +'''('''+ + '+CONVERT(varchar(20),pol_id)'

+'+'')'''+ ' from '+ @dbname + '.dbo.Organization'+ ' where OrganizationID =' + convert(varchar(10),@orgid)
