case for date

I have select statement that includes the following:
DATEADD (mm,+1,(tblUser.BILLMON +'01') ) AS TransDate,
There are some instances where tblUser.BILLMON ='000000' (usually it is 201205...or something like that)
I want a case added to the beginning of this to handle the '000000'...how could I go about it?

I expect tblUser.BILLMON is a (n)varchar field, and it may also be 'not null' with a default of '000000'

in other words there is probably no way of knowing what '000000' represents - so do you want NULL?

case
      when tblUser.BILLMON ='000000' then NULL
      else DATEADD (mm,+1,(tblUser.BILLMON +'01') )
end AS TransDate
