Your information has changed, so the advice changes. 

If you just need the second encounter 

bysort ID (billid) : keep if _n == 2

Thanks for your suggestion. In this database a person can be
hospitalized 2 or more times. The first hospital encounter has final
bill information. The second hospital encounter has 2 interim bills
and 1 final bill. Please suggest stata code to collapse billing
information for second hospital encounter only . Procedure variables
are string for those bills.
