The health insurance company that insured Peter pays 80% of nutritional counseling after Peter pays a $50 deductible the cost of the counseling was $1,060

Peter will pay:

$50 deductible 20% x ($1,060 - $50) = $202 total $252

the insurance company will pay:

(total counseling cost - deductible) x 80% = ($1,060 - $50) x 80% = $808

The deductible refers to the amount of money an insured has to pay before the health insurance company starts to pay partially or completely for your health treatment. deductibles are commonly used for other types of insurance policies also, including auto insurance.
