A deductible is the amount you pay each year before your plan begins paying benefits. This amount is usually a set dollar amount such as $250 or $500.
A co-payment is a cost sharing agreement in which you pay a flat-dollar fee for a specific service. An example would be where the insurance plan charges a flat $25 co-payment for primary care visit. Each payor and plan will have its own set amount for the co-pay. This is determined by the contract between the patient and their insurance.
Co-insurance is a percentage owed by the patient after the insurance payment. An example is the insurance plan pays 80% and the patient responsibility is then 20% after the deductible has been met.
Non-Covered-Amount that is not covered by the insurance plan and may be patient responsibility to pay.
