This is a CMS and eligibility engine that I developed for a health care company. Each health insurance company has 20-50 different rules that determine if a patient is eligible for a DNA test. The health insurance rules are based on the patient's medical history and the patient's family medical history. A rule might be "patient must have this disease before age 50"; or "patient must have this disease at any age and the patient must have 2 first or second degree relatives with these diseases before age 45". So I built a CMS that allowed us to input all those rules into the database.
