Group Health Insurance Basics

This is the “Group Health Insurance Basics” section of the Employee Benefits FAQ Library.

Group health insurance is health coverage provided by an employer to employees and often their dependents. Instead of individuals purchasing insurance on their own, the employer sponsors a policy through an insurance carrier. Employers typically share the cost of premiums with employees and may offer multiple plan options.

Group plans often provide broader coverage and more favorable pricing compared to individual policies because risk is spread across a larger group of participants.

Eligibility for group health insurance is determined by the employer’s benefit plan design and the insurance carrier’s requirements. Most plans define eligible employees as those who work 30 or more hours per week, though some employers may choose different eligibility thresholds.

Employers may also extend coverage to:

  • Spouses
  • Domestic partners (depending on the plan)
  • Dependent children

Eligibility rules must be applied consistently to comply with federal regulations.

Most insurance carriers require at least two eligible employees to establish a group health plan. This requirement ensures that the policy truly represents a group rather than an individual policy.

Small businesses commonly offer group health insurance once they reach two employees, though eligibility rules may vary slightly by carrier and state.

Under the Affordable Care Act (ACA), employers with 50 or more full-time equivalent employees (FTEs) are considered Applicable Large Employers (ALEs). These employers are generally required to offer health insurance that meets certain affordability and coverage standards.

Employers with fewer than 50 employees are not federally required to offer coverage, though many choose to do so to remain competitive when recruiting and retaining employees.

Yes. Small businesses with as few as two employees can typically offer group health insurance through most carriers. Small employer plans are designed specifically for businesses with fewer employees and may provide multiple coverage options.

Offering benefits can help small businesses:

  • Attract qualified employees
  • Improve retention
  • Support employee health and productivity

Many employers provide a comprehensive benefits package that includes multiple types of coverage.

Common benefits include:

  • Medical insurance
  • Dental insurance
  • Vision insurance
  • Life insurance
  • Disability insurance
  • Voluntary benefits such as accident or critical illness insurance

Employers may also offer retirement plans, wellness programs, and other benefits depending on company size and strategy.

Health plans differ in how they manage provider networks and referrals.

HMO (Health Maintenance Organization)
Requires employees to select a primary care physician and obtain referrals for specialists. HMOs often have lower premiums but less flexibility.

PPO (Preferred Provider Organization)
Offers more flexibility and allows members to see specialists without referrals. PPO plans typically allow out-of-network care at a higher cost.

EPO (Exclusive Provider Organization)
Requires members to use providers within the plan’s network but typically does not require referrals.

Employers may offer one or more plan types so employees can choose coverage that fits their needs.

Yes. Many employers offer multiple plan options so employees can choose coverage based on their needs and budget. For example, an employer might offer:

  • A lower-premium, higher-deductible plan
  • A richer plan with lower out-of-pocket costs

Offering multiple options allows employees to select the plan that works best for their healthcare usage and financial situation.

Voluntary benefits are optional insurance products employees can choose to purchase, often through payroll deductions. These benefits supplement traditional medical coverage and can provide financial protection for unexpected events.

Common voluntary benefits include:

  • Accident insurance
  • Critical illness insurance
  • Hospital indemnity insurance
  • Supplemental life insurance

Because employees typically pay the full cost, voluntary benefits allow employers to expand benefit offerings without significantly increasing employer expenses.

Employers offer benefits to support employees while also strengthening their overall workforce strategy.

Benefits programs help organizations:

  • Attract qualified talent
  • Improve employee retention
  • Enhance employee wellbeing
  • Increase job satisfaction
  • Stay competitive in the labor market

A well-designed benefits program can be a key component of a company’s compensation strategy.
