You can either put another case or use decode (as @madhu suggested): 

select case 
  when value in (1000) then null
  when user in ('ABC') then user
  when area in ('DENVER') then
    case when value = 2000 then 'Service1'
         when value = 3000 then 'Service2'
    end 
  else null
  end as num_code 
from service_usoc_ref;

This could help you 

 select  case when value in (1000) then null
                         when user in ('ABC') then user
                       when area in ('DENVER') then
decode( value, 2000 , 'Service1',3000 , 'Service2', NULL)  num_code 
from service_usoc_ref;
