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.
Income tax in the United States
Most personal, living, and family expenses are not deductible. Business deductions allowed for Federal income tax are almost always allowed in determining state income tax. Only some states, however, allow itemized deductions for individuals. Some states also limit deductions by corporations for investment related expenses. Many states allow different amounts for depreciation deductions. State limitations on deductions may differ significantly from Federal limitations.
