Group Health Insurance is typically provided by employers to their employees and their families. It offers coverage for a range of medical expenses and is often more affordable than individual health insurance plans.

Large employers often negotiate lower premiums with insurance companies, provide access to a wider network of providers, and contribute a portion of the premiums, making health insurance more affordable and accessible for employees.

ERISA is the primary federal law that regulates group health insurance plans offered by employers. It sets standards for participation, benefits, funding, and reporting requirements.

Under ERISA, the maximum annual deductible for group health insurance plans is set at $2,500 for individual coverage and $5,000 for family coverage.

PPO plans offer the most comprehensive coverage among the listed options. They allow members to choose providers both within and outside of the network, providing greater flexibility and choice.

Employer Contribution refers to the portion of the health insurance premium paid by the employer. It is a common practice for employers to contribute a certain percentage of the premium, making health insurance more affordable for employees.

COBRA is the federal law that allows employees to continue their group health insurance coverage after leaving their job. It provides temporary coverage for a specified period, typically 18 or 36 months, at the employee's expense.

For employees who leave their job voluntarily, COBRA coverage typically lasts for 18 months. However, certain exceptions may allow for coverage to extend up to 36 months.

EPO plans have a limited network of providers, which allows them to offer lower premiums compared to other types of plans. However, members are required to stay within the network for covered services.

Deductible refers to the out-of-pocket expenses that an insured individual is responsible for paying before the insurance coverage starts. Once the deductible is met, the insurance company begins to cover a portion of the medical expenses.

POS plans offer a wide range of medical services and allow members to choose providers both within and outside of the network. However, members may pay higher out-of-pocket costs for services received outside the network.

HMO plans require members to choose a primary care physician (PCP) who coordinates their care. The PCP is responsible for referring members to specialists and authorizing medical services.

Copayment refers to the fixed amount that an insured individual pays for a specific medical service, such as an office visit or prescription drug. It is typically a small, flat fee.

HIPAA prohibits group health plans from denying coverage or charging higher premiums based on an individual's health status. It also ensures that individuals can keep their health insurance coverage when they change jobs or lose their job.
