Final answer:
After the deductible and copayment, the patient pays a percentage known as coinsurance, which constitutes the patient's share of the covered services.
Step-by-step explanation:
The percentage that a patient pays for covered services after the deductible has been met and the copayment has been paid is known as coinsurance. Coinsurance is a cost-sharing arrangement where the insured pays a set percentage of the medical costs, and the insurance company pays the remaining amount. For instance, if the coinsurance rate is 20%, the patient would pay 20% of the costs, while the insurance company would cover the remaining 80%. This system is designed to prevent moral hazard by ensuring that patients have a financial responsibility in their healthcare costs, encouraging them to make more cost-effective healthcare decisions.
