Sarahs comprehensive major medical health insurance plan at work has a deductible of $800. The policy pays 80 percent of any amount above the deductible. While on a hiking trip, she contracted a rare bacterial disease. Her medical costs for treatment, including medicines, tests, and a six-day hospital stay, totaled $9,710. A friend told her that she would have paid less if she had a policy with a stop-loss feature that capped her out-of-pocket expenses at $3,800. The policy with the stop-loss feature has the same deductible and coinsurance requirement as Sarah's current policy.

What is the different amount?
