sql oracle in() clause

Is it possible to use in() clause in case.. when ...the construction in sql query condition expression.

im my case the query is very long:

select  r.insurance_package_id,r.name,
       max(case r.insurance_package_id when 6 then r.name  
                                       when 7 then r.name  
                                       when 8 then r.name  
                                       when 9 then r.name  
                                       when 10 then r.name  
                                       when 11 then r.name  
                                       when 12 then r.name  
                                       when 14 then r.name    
                                       when 42 then r.name    
                                       when 44 then r.name  
                                       when 7 then r.name  

                 end) CPI_Life  

there are about 200 id supposed to be used in condition expression: thus, the query would be very brut.
