Abstract: Systems and methods are described herein to provide a health care account processing solution that can (1) provide financial security when a participant experiences unexpected major medical expenses the participant may not otherwise be able to afford, (2) provide control of health care decisions to participants and providers, (3) reduce overhead and structural costs required to administer traditional health insurance plans, (4) reduce over-utilization and under-utilization of health care through a participant-controlled health care spending account that can be coupled with a health and wellness program (e.g., a rewards-based wellness program), and (5) encourage provider competition through the use of cash based, point-of-sale payments and transparent pricing. The systems and methods discussed herein describe, among other things, computer-implemented, rules-based systems for managing the health care accounting solution introduced above.
