Following the final whistle, the striker appeared to confront supporters seated in the Colombia section of the Bank of America Stadium in North Carolina after a brawl broke out near to wear the Uruguay team's families were seated.
Uruguay had just been beaten 1-0 by Colombia, who played the whole of the second half with 10 men, to miss out on a place in the final.
Nunez, who was captured in video footage throwing a chair towards where Colombia supporters were sitting, has also received a ã15,000 fine.
Tottenham's Rodrigo Bentancur, who was involved in the fracas, has been given a four-game international ban and fined ã12,000, whilst Mathias Olivera, Ronald Araujo and Josema Gimenez have each been suspended for three matches.
Uruguayan football officials defended their players in the aftermath of the incident, claiming they were simply trying to prevent their families from coming to harm.
Uruguay head coach Marcelo Bielsa rejected any suggestion his players should be sanctioned, saying: "The only thing I can tell you is that the players reacted like any other human being would.
"If you see your woman, or your mother, or a baby, being attacked, what would you do? You'd ask whether they're going to punish the people who defended themselves?"
The ban means Nunez will miss his country's upcoming World Cup qualifying matches against Paraguay, Venezuela, Peru and Ecuador.
