Large group health insurance underwriting can be a complex process, but understanding the basics can help you navigate it with confidence.
The primary goal of underwriting is to assess the risk of insuring a large group, which involves evaluating the group's demographics, claims history, and other relevant factors.
A large group is typically defined as 51 or more employees, and underwriting for these groups often involves a more detailed and comprehensive process than for smaller groups.
Underwriters will review the group's claims history, including any pre-existing conditions, to determine the likelihood of future claims.
The Underwriting Process
The underwriting process for large group health insurance is a complex and nuanced process that involves evaluating the collective health risks of a group of people.
Unlike other forms of insurance underwriting, health insurance underwriting assesses the risk and calculates premiums based on detailed information about the group members, including demographic data, medical history, and information on pre-existing conditions.
This information is critical in determining the insurance premium, coverage options, and exclusions that will apply to the group insurance policy.
The underwriter uses this data to assess the risk and calculate premiums, making it essential to provide accurate and comprehensive information during the underwriting process.
The underwriting process requires a thorough evaluation of the group's health risks, which can impact the premium and coverage options for the group insurance policy.
Importance and Principles
Underwriting in large group health insurance is crucial for assessing the collective risk of a group. This involves evaluating the medical history, age, occupation, and sometimes lifestyle choices of the group members.
The primary goal of underwriting is to ascertain the potential healthcare costs that the insurer might incur. This is essential for providing coverage at rates that are both competitive and financially sustainable.
The underwriter plays a crucial role in balancing the need for comprehensive coverage for the policyholder with the financial risks posed to the insurance company. Without proper underwriting, insurers may struggle to provide affordable coverage, or worse, go out of business.

The primary goal of underwriting is to ascertain the potential healthcare costs that the insurer might incur. This helps ensure that the insurance company can provide coverage at rates that are both competitive and financially sustainable.
Underwriters consider a group's medical history to determine the likelihood of future healthcare costs. They also take into account the age of the group members, as older individuals may require more medical care.
Insurance companies use the information gathered during the underwriting process to set premiums that reflect the group's risk level. This helps balance the need for comprehensive coverage with the financial risks posed to the insurance company.
Industry Norms
Industry norms play a significant role in the underwriting process, and insurers often follow guidelines from reputable bodies like the Kaiser Family Foundation.

These guidelines provide valuable insights into average costs and risks associated with various demographics and medical conditions.
Insurers rely on these norms to make informed decisions about policyholders, and they can help ensure that premiums are fair and reflective of actual risk.
By following industry norms, insurers can also help maintain a level playing field and prevent unfair practices.
Risk Evaluation and Analysis
Risk Evaluation and Analysis is a critical component of large group health insurance underwriting. It involves quantifying the likelihood and potential cost of future claims.
The outcome of the risk analysis can lead to different policy terms, such as higher premiums or more exclusions in the insurance policy. For instance, a group with higher health risks might face higher premiums.
In modern underwriting, technology plays a pivotal role in processing large volumes of information quickly and accurately. Advanced data analytics and algorithms enable underwriters to identify patterns and predict future claims more accurately.
The underwriting process directly affects the pricing of an insurance policy, with factors such as the overall health of the group and the presence of chronic conditions playing into premium calculations. Insurance companies also consider the age distribution of the group members.
Insurance companies use medical histories to determine if they can offer a policy and to determine the premium. They are mostly looking at pre-existing conditions, and the premium amount can change depending on the type and severity of these conditions.
Methods and Techniques
Underwriters use various methods to evaluate risk, including statistical models, historical claim data, and actuarial tables.
The Affordable Care Act has introduced adjustments in how risk is assessed, especially for pre-existing conditions.
In the realm of group health insurance, underwriters evaluate the collective health risks of a group of people, rather than individuals.
This process is critical in determining the insurance premium, coverage options, and exclusions that will apply to the group insurance policy.
Underwriting in the group health sector involves a complex and nuanced process, unlike other forms of insurance underwriting.
Policy Terms and Pricing
Policy terms and pricing are deeply connected in large group health insurance underwriting. The outcome of the risk analysis can lead to different policy terms, such as higher premiums or more exclusions, for groups with higher health risks.
Factors like the overall health of the group, the presence of chronic conditions, and the age distribution of group members all play into premium calculations. These factors can significantly impact the cost of insurance for your company.
Insurance companies use medical underwriting to determine policy terms and pricing. They examine employees' medical histories to assess their health risks.
The type and severity of pre-existing conditions can change your premium amount. Insurance companies often look for these conditions when determining premium rates.
Policy pricing is directly affected by the underwriting process. Employers, policyholders, and insurers must understand these nuances to navigate the complexities of the health insurance landscape.
Guidelines and Regulations
Large group health insurance underwriting involves a thorough review of a company's financial health and employee demographics. This process typically takes 30 to 60 days.
The Affordable Care Act requires employers with 50 or more full-time employees to offer health insurance to their staff. This is often referred to as the "50+ employee rule."
Employers with 50 to 99 employees may be eligible for a small group health insurance plan, which has different underwriting requirements. For example, these plans may not require a waiting period for new employees.
The underwriting process for large group health insurance typically involves a review of the company's financial statements, including income statements and balance sheets. This helps insurers assess the company's risk and determine premiums.
Large group health insurance plans often have a maximum out-of-pocket (MOOP) limit, which can range from $7,000 to $13,000 per year, depending on the plan. This limit is set by the Affordable Care Act.
Group Health Insurance
Large group health insurance underwriting is a process that involves evaluating the health and medical history of a group's employees to determine the premium rates for their health insurance coverage.
The size of the group plays a significant role in determining the underwriting process, with larger groups having more complex underwriting requirements.
For large groups, coverage is medically underwritten, meaning rates are based on employee participation, type of industry, coverage selected, and a group's prior medical claims costs, if known and available.
This means that a group's claims experience will be reviewed at renewal to determine rates for the following year, with the potential for no rate change, an increase, or a decrease.
Limited medical questions may be asked of employees, depending on the group size, but detailed health questionnaires are generally not required for larger groups to be quoted and enrolled.
In California, small businesses with up to 100 full-time employees can purchase health insurance coverage with age-based rates for employees and adult dependents.
The ACA prevents insurers from charging unreasonable rates by limiting the rates for older employees to no more than three times the rates for younger employees.
Dependent children can be covered on a parent’s health policy until they turn 26, and children’s rates are the same for those 0-14.
In Nevada, small businesses with up to 50 full-time employees can also purchase health insurance coverage with age-based rates.
The Small Group health insurance carriers working with Word & Brown do not include tobacco use as a rating factor, providing only one set of rates to us.
Employers with larger groups are more likely to offer health insurance benefits to their workers, with nearly all firms with 1,000 or more workers offering coverage to at least some workers.
In California, about 48% of residents have employer-sponsored health insurance, which amounts to over 18 million residents.
Premiums and Contributions
In large group health insurance, employers typically share the cost of premiums with their employees. Most insurers require a 50% contribution by employers.
The average annual worker contribution for single coverage is $1,299, which represents nearly 17% of the total single coverage premium of $7,739.
Many businesses choose to contribute more than the minimum required by insurers. Some employers pay the entire premium for single coverage, which accounts for 29% of covered workers at small firms.
For family coverage, the average annual worker contribution is $5,969, or nearly 27% of the total family coverage premium of $22,221. In some cases, employees contribute more than half of the premium for family coverage, which affects 31% of covered workers at small firms.
Claims and Membership
Large group health insurance underwriting requires a significant amount of data from employers with over 100 employees. You'll need to provide 24 months of monthly claims, including the amount paid and incurred each month.
This can be a complex task, especially if you have a high employee turnover rate. To give you an idea, employers with over 100 employees will need to provide a monthly count of group health enrollees for the past two years.
High-cost claims are also a consideration, defined as claims exceeding $25,000 per 12 months. If you have employees with such claims, you'll need to provide that information to your insurance company.
Employers with 50-100 employees are exempt from providing this level of detail, which is a relief for smaller businesses.
Plan Options and Differences
Large group health insurance underwriting involves evaluating the health risks of a group of employees. This process can be complex, but understanding the key differences between plan options can help you make an informed decision.
There are generally two types of underwriting methods: experience-rated and community-rated. Experience-rated plans assess the health risks of the group based on their past claims history, while community-rated plans charge all groups the same rate, regardless of their claims history.
The key difference between these two methods is how they determine premiums. Experience-rated plans charge premiums based on the group's actual claims history, while community-rated plans charge premiums based on the average claims history of all groups in the area.
Experience-rated plans can be more cost-effective for groups with low claims history, but they can also be more expensive for groups with high claims history.
Alternative Large Plan Options
For large businesses, traditional group health insurance is not the only option. Other than traditional group health insurance, the only other option available is self-insurance or self-funding.
Self-insurance or self-funding means the employer assumes the financial risk, paying health claims for employees as they occur. This can potentially lead to premium savings, but it also comes with added costs such as stop-loss coverage for catastrophic claims and a third-party administrator to handle claims.
Traditionally, self-insured plans have been used primarily by larger groups, but smaller groups have started to consider self-funding with the introduction of level-funding.
Small vs Large Plans: Key Differences

In California, a Large Group is defined as having 101 or more full-time or full-time-equivalent employees.
The definition of a Large Group varies by state, with Nevada defining it as employers with more than 50 full-time or full-time-equivalent employees.
Full-time equivalent workers are those not working full time, but who in combination are counted toward the equivalent of a full-time worker.
If an employer has at least 50 full-time employees, including full-time equivalents, the business is an Applicable Large Employer (ALE).
This means the business must offer affordable health insurance coverage that offers minimum value to 95% of full-time employees and dependent children until they turn age 26.
Large Differentiators
Large groups have some significant differences compared to small groups. One key difference is in the rates they pay for health insurance. Large groups have custom rates that are experience-rated, whereas small groups have age-banded rates with no room for negotiation.
Large groups may also be eligible for additional discounts and perks, such as bundling discounts, premium holidays, and wellness allowances. These can help reduce the cost of coverage for employees.
Another difference is in the types of plans available. Small groups can choose from Metallic Plans, including Bronze, Silver, Gold, and Platinum options. Large groups, on the other hand, do not have access to these plans.
In California, Large Groups may not be eligible for the DE 9C plan, which is available to small groups. Pediatric Dental and Vision are also not required in the Large Group marketplace, unlike small groups where they are Essential Health Benefits.
The Medical Loss Ratio (MLR) is another area where Large Groups differ from small groups. The MLR for Large Groups increases to 85%, meaning that 85% of premium dollars are spent on healthcare-related expenses, with no more than 15% spent on administrative costs, marketing, and profits.
ACA and Underwriting
The Affordable Care Act (ACA) has significantly impacted the way large group health insurance underwriting is done.
Under the ACA, group health plans are prohibited from requiring medical underwriting for new employees, except in certain circumstances.
Medical underwriting for new employees is only allowed if the employee is enrolling in the plan outside of open enrollment or a special enrollment period, and the employer has a grandfathered plan.
In a grandfathered plan, the employer has chosen not to comply with certain ACA provisions, and the plan is allowed to continue with its existing underwriting practices.
Grandfathered plans are not required to offer the same level of coverage as non-grandfathered plans, and they may have higher out-of-pocket costs for employees.
Frequently Asked Questions
What is considered a large group in insurance?
A large group in insurance typically consists of businesses with 51 or more employees, offering a wider range of benefits and customization options. This size threshold allows for more comprehensive coverage and flexibility.
What is the reason for requiring a minimum group size when underwriting group health insurance?
To prevent adverse selection, insurance companies require a minimum group size of 70% full-time employees to be enrolled in a group health insurance plan. This ensures that the risk pool is large enough to make group health coverage affordable for everyone.
