Nope, it doesn't. The Ka-50 is the only production helicopter to be equipped with an ejection seat.
Part of the reason other attack helicopters don't have them is that ejection seats in helicopters add complexity and weight for not that much of an increase in survivability, considering the usual flight profiles that these helicopters fly.
It makes more sense to focus on improving the survivability of crashes through measures such as collapsing seats and landing gear designed to absorb impact forces. With these types of improvements the crew of modern helicopters can survive even severe accidents without serious injury.
