Managed care
In terms of using such a plan, unlike an HMO plan, which has a copayment cost share feature (a nominal payment generally paid at the time of service), a PPO generally does not have a copayment but offers a deductible and a coinsurance feature. The deductible must be paid in full before any benefits are provided. After the deductible is met, the coinsurance benefits apply. If the PPO plan is an 80% coinsurance plan with a $1,000 deductible, the patient pays 100% of the allowed provider fee up to $1,000. The insurer will pay 80% of the other fees, and the patient will pay the remaining 20%. Charges above the allowed amount are not payable by the patient or insurer but written off as a discount by the physician.
Taxation in the United States
The U.S. system allows reduction of taxable income for both business and some nonbusiness expenditures, called deductions. Businesses selling goods reduce gross income directly by the cost of goods sold. In addition, businesses may deduct most types of expenses incurred in the business. Some of these deductions are subject to limitations. For example, only 50% of the amount incurred for any meals or entertainment may be deducted. The amount and timing of deductions for business expenses is determined under the taxpayer's tax accounting method, which may differ from methods used in accounting records.
