                               THEN 20

                          ELSE 21
                     END 

if the age band is 0-10 the all values between 0 and 10 must be reflected

Answer 1

To me it looks like that you need something like this:

WHERE 
  AGE >= convert(int, left(@timeGrain, charindex ('-', @timeGrain) - 1)) and
  AGE <= convert(int, substring(@timeGrain, charindex ('-', @timeGrain) + 1, 9999))

This will split the timegrain from - and use those as upper / lower limit. For the else part, you probably need to have some kind of OR -clause, but can't write it since I have no idea what your possible value is in that case.

Answer 2

Try this instead

SELECT dbo.ClaimDataFormat.AGE,
       dbo.ClaimDataFormat.RELATION,
       dbo.ClaimDataFormat.NAME,
       dbo.ClaimDataFormat.ENTRY_DATE,
       dbo.ClaimDataFormat.CLAIM_AMT,
       CASE
         WHEN dbo.ClaimDataFormat.Gender = 'F' THEN 'FEMALE'
         ELSE 'MALE'
       END AS GENDER,
       dbo.ClaimDataFormat.STATUS,
       dbo.ClaimDataFormat.APPROVED_AMT
FROM   dbo.ClaimDataFormat
WHERE  ( dbo.ClaimDataFormat.AGE BETWEEN 0 AND 10
         AND TimeGran = '0-10' )
        OR ( dbo.ClaimDataFormat.AGE BETWEEN 11 AND 20
             AND TimeGran = '11-20' )
        OR ( dbo.ClaimDataFormat.AGE = 21
             AND TimeGran NOT IN ( '0-10', '11-20' ) )
