The PokitDok app allows consumers to search for value among health care providers as travelers might use Priceline: by naming their price. More than a million health care providers participate in the program, which responds to Web-based or mobile requests for a price quote indicating a consumer's budget, payment method and needs, as well as practitioner preference. Doctors have an incentive to join the system to connect with patients paying out of pocket or through a health savings account or flexible spending account, says PokitDok CEO Lisa Maki.
