How do you use hex in Verilog?

Hex in Verilog are 16 based integers. I usually explicitly define the size, then type "'h" and then the value. I use hex values when I need some hardware-close representation of data: register's fields, sometimes in arithmetic, floating point representation, etc.

localparam mask = 16'hfc73;
reg [15:0] rega = 16'h0e58;
assign fields = rega & mask;

8'h23 = 35 (Decimal) = 0010_0011 (Binary)
