Employers and employees may have some choice in the details of plans, including health savings accounts, deductible, and coinsurance. As of 2015, a trend has emerged for employers to offer high-deductible plans, called consumer-driven healthcare plans which place more costs on employees, while employees benefit by paying lower monthly premiums. Additionally, having a high-deductible plan allows employees to open a health savings account, which allows them to contribute pre-tax savings towards future medical needs. Some employers will offer multiple plans to their employees.
