Blind cut from Koeman's first Netherlands squad
The 28-year-old was included in a 33-man preliminary squad for international friendlies against England and Portugal this month.
But Blind, who has not played for United since January 5 due to an ankle injury, was among those cut from the final group.
PSV's Luuk de Jong and Wolfsburg's Jeffrey Bruma have also been left out by Koeman, who handed maiden call-ups to a number of young players including Ajax's teenage forward Justin Kluivert - son of Netherlands icon Patrick.
Marco Bizot, Hans Hateboer, Guus Til and Wout Weghorst are also in the Netherlands squad for the first time.
