The Rama in his Darkei Moshe writes that we pasken like Tosfos that today mayim achronim is not necessary.
However, The Mechaber 181:10 writes that there is an opinion who holds we don't do mayim achronim, but the Rama does not say anything on this se'if, why doesn't the Rama say V'haci Noheg like in the Darkei Moshe?
