A McKinsey survey showed that people enrolled in HSAs or other consumer-driven plans were 50% more likely to ask about overall costs of health care services, and 100% more likely to ask about drug costs, compared with people in traditional health care plans.
Similarly, a Blue Cross Blue Shield Association study showed that 33% of HSA enrollees asked about prescription costs, compared with only 18% of enrollees in traditional plans. Of those in HSAs, 20% asked about the costs of physician visits, versus 14% of those who have traditional insurance.
