In a catastrophic health care strategy, you maintain a higher deductible in exchange for a lower premium. You benefit by paying a lower premium every month. The insurance company benefits by spending less time, energy, and money on your health matters.
I follow this strategy. I am carrying a $3,500 deductible on my health insurance and am paying a lower premium than if I were carrying a lower deductible. If I fall off my bike and break a finger, I would probably pay my medical costs out of pocket. If I fall off my bike because I had a stroke, my medical costs would exceed $3,500 and the insurance would take effect. From Escape the Cubicle
