In FIBA, according to what I've read, the numbers allowed are 4-15. When reporting a number after 10, the right hand is closed with the left hand showing 1-5 fingers. For single digits above 5, the mechanic/procedure is the right hand shows 5, the left hands shows the additional numer of fingers needed for 6-10.

However I thought that for NFHS reporting all fouls are actually supposed to be reported one-handed. When the 1st number is called, the palm of the hand is supposed to be facing the official with the numer of fingers showing for that number. The second numer is done via palm facing the table with the appropriate fingers.
