Group health insurance remains the most common way employers solve this problem. But choosing the right plan means understanding participation rules, plan types, costs, and compliance requirements that shift depending on your company's size.
Muneris Benefits has helped hundreds of employers across Virginia and West Virginia navigate these decisions since 1990. This guide breaks down what group health insurance actually is, how it works, and how to choose a plan that fits your business.
Key Takeaways
- Group plans pool risk across employees, which can stabilize premiums compared to individual coverage
- Premium costs are typically split with employees, and carriers require participation minimums
- Plan types (HMO, PPO, EPO, POS) trade cost against provider flexibility
- ACA mandates apply at 50+ full-time employees; smaller firms have more options, including MEWAs
- A licensed broker helps you compare carriers and avoid compliance missteps
What Is Group Health Insurance?
Group health insurance is a single policy that covers all eligible employees of a business under one set of standardized benefits. The employer negotiates directly with an insurer, and premiums are usually split between the company and its workers.
This differs from individual insurance, where a person shops for and buys their own plan on the open market. With group coverage, the employer selects the plan design; employees enroll into it rather than customizing their own.
Employer-sponsored insurance is the main way most Americans get health coverage. According to the U.S. Census Bureau's 2024 report on health insurance coverage, employment-based insurance covered 53.8% of the population for some or all of 2024 — making it the single largest source of coverage in the country.
Many employers bundle other group benefits alongside health coverage, including:
- Life insurance
- Disability insurance
- Dental coverage
- Vision coverage
Group Policy vs. Individual Policy Card
Employees can tell the difference at a glance. A group insurance card typically displays a group number alongside the member ID that identifies the employer's master policy. Individual policy cards don't carry this group number since there's no employer sponsoring the coverage.
How Group Health Insurance Works
With group health insurance, the employer sponsors a plan and eligible employees enroll as a shared risk pool. The carrier prices coverage based on that group, not each person alone.
Before a plan goes live, insurers require a minimum share of eligible employees to enroll. That rule protects the risk pool from adverse selection — if only sicker employees sign up, costs spike for everyone.
Participation rules vary by carrier and aren't standardized. For example:
- UnitedHealthcare generally requires 75% of eligible employees to enroll in contributory plans, with a floor of 50% of all eligible employees
- Cigna's Tennessee small-group application requires just 25% participation, plus at least one eligible full-time employee
Confirm your carrier's exact threshold before you lock enrollment timing.
Enrollment Windows
Employees typically gain access to group coverage during:
- Open enrollment – an annual window set by the employer
- New hire enrollment – usually within 30-60 days of a start date
- Qualifying life events – marriage, birth, loss of other coverage, etc.
Plan Types Employers Choose From
| Plan Type | Network Flexibility | Typical Cost | Best For |
|---|---|---|---|
| HMO | Lower | Lower premiums | Cost-focused groups OK with a defined network |
| PPO | Higher | Higher premiums | Teams that want out-of-network access |
| EPO | Moderate | Moderate premiums | Network savings without referral rules |
| POS | Moderate | Moderate premiums | PCP-managed care with limited out-of-network options |
According to KFF's 2025 Employer Health Benefits Survey, PPO plans remain the most popular, covering 46% of enrolled workers, followed by high-deductible plans (33%) and HMOs (12%).
What This Costs
The same KFF survey reports these average annual figures:
- Single coverage: $9,325 total premium; workers pay about $1,440
- Family coverage: $26,993 total premium; workers pay about $6,850
Employers still cover most of the premium. Smaller firms shift more to workers: at companies with 10–199 employees, workers paid 36% of family premium costs, versus 23% at larger firms.
Advantages and Disadvantages of Group Health Insurance
Group coverage isn't automatically "cheaper" for every business, but the trade-offs are real and worth weighing.
Advantages:
- Spreads cost across a larger group for more predictable, often lower per-person premiums
- Lets employees enroll without medical exams or health questionnaires
- Treats employer-paid premiums as deductible business expenses; those contributions aren't counted as employee wages for payroll tax
That tax treatment has one notable exception: S-corp owners who hold more than 2% of company shares don't get the same break on their own health benefits, per IRS guidance.
Disadvantages:
- Limits how much employees can tailor coverage to their own situation
- Ends when employment ends, unless COBRA or a similar continuation option applies
- Adds enrollment, billing, and compliance work that hits hardest without dedicated HR staff
Choosing the Right Group Health Plan for Your Business
There's no universal "best" plan — the right choice depends on your company size, budget, and workforce.
Smaller employers often have more flexibility than they realize. Alliance and MEWA (Multiple Employer Welfare Arrangement) options can give small businesses access to group buying power typically reserved for larger companies.
When comparing options, look beyond the first quote:
- Compare multiple carriers, not just one
- Evaluate plan tiers against your workforce's actual healthcare usage patterns
- Ask about cost-containment tools like HSAs and HRAs to lower premiums and long-term cost trends
This is where a licensed broker earns their value. Muneris Benefits, for example, is a WiseChoice Healthcare Alliance Certified MEWA Advisor, which gives employers access to group buying strategies that help make coverage more affordable for Virginia and West Virginia small businesses.
The firm builds customized benefit packages with consumer-driven health plans, HSAs, and HRAs rather than defaulting to one carrier’s standard offering.
Compliance and Legal Considerations for Employers
Compliance obligations scale with company size, and getting them wrong is expensive.
The ACA employer mandate applies to Applicable Large Employers (ALEs) — generally businesses averaging 50 or more full-time employees (including full-time equivalents) in the prior year. An employee counts as full-time at 30+ hours per week.
ALEs that fail to offer minimum essential coverage to at least 95% of full-time employees can face penalties. According to IRS guidance on employer shared responsibility, the 2024 adjusted penalty amounts were $2,970 or $4,460 per employee, depending on the violation type.
Ongoing obligations don't stop at the mandate. Employers also need to manage:
- ACA reporting — ALEs file Forms 1094-C and 1095-C annually
- COBRA continuation coverage — required for employers with 20+ employees, generally offering 18 months of continued coverage after a qualifying event
- Nondiscrimination rules — insured group plans must comply with ACA nondiscrimination provisions
A benefits adviser can help you keep pace with these rules. Muneris Benefits' HR consulting covers COBRA and ACA compliance guidance, plus daily account-manager support for billing and claims questions.

What is the best health insurance for a small business?
The "best" plan depends on your company size, budget, and employee needs. Comparing multiple carrier options through a broker often yields more competitive rates than going direct to one insurer.

What is not covered in group health insurance?
Common exclusions include certain elective procedures, most out-of-network specialist care, and some dental or vision services not built into the base medical plan.
What is a group policy in health insurance?
A group policy is a single master contract that covers all eligible members of an organization under one insurer, rather than each person holding a separate individual policy.
