The plan has a $1000 calendar-year deductible, a 80/20 coinsurance, and an annual out-of-pocket limit of $3,000. As aresult of the accident, Margo incurred the following medical expenses: Cost of ambulance to the hospital $500 Hospital bill for a three-day stay $24,000 Surgery for a broken leg $ 5,000 Prescription drugs outside the hospital $300 Physical therapy for the broken leg $1200 In addition, Margo could not work for one month and lost $4000 in earnings. a. Based on the above, how much will Margo collect for her injury if she receives medical care from health care providers who are part of the PPO network? (Assume that all charges shown are the allowable or approved charges by the insurer and all providers are in the PPO network.) b.

Margo would like a different surgeon with an outstanding professional reputation to perform the operation. The surgeon is not a member of the PPO network. Will Margo's plan pay for the surgery?
