Williams called Ramos a “liar” and a “thief” having already received a point penalty for smashing her racquet.
The 37-year-old was also handed a code violation for coaching during the final in New York, which she lost in straight sets.
US Open referee Soeren Friemel says the decision is a good one for the tournament, the players and the umpires.
“It’s not the first time that we made decisions that is good for the tournament, is good for the players, and is good for the umpires as well to not be on those matches.
“In the end, our goal is to assign the best chair umpire for the right match so in taking all those factors into consideration, the decision was made that he would not do any of the Williams sisters’ matches.”
In heated exchanges in last year’s final, Williams told Ramos “you will never, ever, ever be on another court of mine as long as you live.”
It is not unusual for umpires to be kept away from players after a contentious match.
Ramos umpired this year’s Australian Open semi-final between Petra Kvitova and Danielle Collins, but has not yet been given the chance to add to his tally of 10 Grand Slam singles finals.
“Carlos has worked all the other Grand Slams,” Friemel added.
“He has done Davis Cup, Fed Cup, and he’s going to work the Davis Cup final so he’s considered still for all high-profile matches.”
