The answer to your question depends on many factors.
First you need to set ArithmeticCoderBase.numStateBits. In Java this value can be in the range [1, 62], and 32 is recommended. In Python this value needs to be at least 1 and has no upper limit.
If you want to encode 16-bit symbols, then you need numStateBits >= 16. More state bits will give you more range for the frequency table.
However, there are other approaches too. I heard that H.264/AVC uses binary arithmetic coding, and I think they convert 16-bit values into a sequence of sixteen 1-bit values and send each bit individually through the CABAC.
