12.1 Group Health Fundamentals and Eligibility
Key Takeaways
- The employer holds the master policy; each employee receives a certificate of insurance that is only a summary, and the master policy controls in any conflict.
- Group coverage spreads risk, lowers per-person cost, and usually waives individual medical underwriting, but ends when employment ends.
- Eligible groups must exist for a purpose other than buying insurance; associations generally must be two years old.
- Full-time, actively-at-work status is required, and the actively-at-work provision can delay an employee's effective date.
- A probationary period delays eligibility (30–90 days), while the 31-day enrollment window is the period to act; late enrollees may need evidence of insurability.
Group health insurance covers a defined group of people under a single contract, most often the employees of an employer. The exam tests how group mechanics differ from individual coverage, who holds the contract, who gets coverage, and the rules that keep healthy and unhealthy members mixed together.
The single biggest conceptual difference is that group insurance underwrites and contracts at the level of the group, not the person. One application establishes the plan, one premium is billed to the sponsor, and individual health is usually irrelevant to whether a given employee can join.
The Master Policy and Certificates
The employer (or other sponsor) is the policyholder and receives the master policy (also called the master contract). The master policy is the actual contract; it contains all benefits, terms, exclusions, and conditions. Individual members do not receive the policy.
Each covered employee receives a certificate of insurance (certificate of coverage). The certificate is only a summary of the coverage and proof of participation. It is not the contract, so if the certificate and the master policy ever conflict, the master policy controls.
Group vs. Individual Coverage
| Feature | Group | Individual |
|---|---|---|
| Contract | Master policy to employer | Policy to insured |
| Document to member | Certificate | Full policy |
| Underwriting | Group/characteristics | Individual medical |
| Cost per person | Lower (spread risk) | Higher |
| Portability | Tied to employment | Owned by insured |
| Renewability | Annual group renewal | Often guaranteed renewable |
The central advantage of group coverage is risk spreading: because a large block of people is insured together, the insurer can charge lower per-person rates and usually waive individual medical underwriting. The central disadvantage is that coverage typically ends when employment ends.
Another distinction is rate control. In an individual policy the insured owns the contract and the insurer often cannot single them out for a rate increase. In a group plan the entire group is re-rated at renewal, so one or two large claims can raise everyone's renewal premium. This is why participation rules and experience rating, covered later, matter so much in the group context.
Eligible Groups
State law requires that a group exist for some purpose other than obtaining insurance to prevent adverse selection. Recognized group types include:
- Single-employer groups – the most common; employees of one company.
- Multiple-employer trusts (METs) and MEWAs – small employers in similar businesses pooling together.
- Labor union groups (Taft-Hartley trusts) – coverage negotiated for members.
- Trade and professional associations – must usually exist for at least two years for purposes other than insurance.
- Creditor-debtor groups – a lender insures borrowers (credit health/disability).
The exam loves the rule that a group formed solely to buy insurance is not an eligible group. Watch also for the distinction between a true single-employer group and a fabricated affinity group. A bowling league or a discount club that springs into existence only to access cheap coverage fails the test, while a long-standing trade association whose insurance offering is incidental to its real purpose passes.
Eligibility, Active Work, and Enrollment Periods
To be covered, an employee usually must be a full-time, actively-at-work employee. The actively-at-work provision requires the employee to be performing normal duties on the day coverage takes effect; an employee home sick on the effective date may have coverage delayed.
Key timing rules tested on the exam:
- Eligibility (probationary) period – a wait of typically 30–90 days after hire before an employee becomes eligible to enroll.
- Enrollment period – usually a 31-day window after becoming eligible to sign up without proof of insurability.
- Late enrollee – an employee who applies after the enrollment window may have to provide evidence of insurability or wait for open enrollment (typically an annual period).
- Special enrollment – a qualifying life event (marriage, birth, loss of other coverage) opens a new window, normally 30 days.
Worked Example: Eligibility Date
Maria is hired on March 1 into a plan with a 60-day probationary period and a 31-day enrollment window. She becomes eligible on April 30 (60 days after hire). Her enrollment window then runs through about May 31. If she enrolls in that window, no evidence of insurability is required. If she waits until August, she is a late enrollee and the insurer may require proof of insurability or make her wait for open enrollment.
Trap: the probationary period delays eligibility; the enrollment period is the window to act once eligible. Candidates frequently confuse the two.
A second timing trap involves dependents. A newborn or newly adopted child is generally covered automatically from the moment of birth or placement, but the plan can require the employee to notify the insurer and pay any additional premium within a set window (often 31 days). Miss the window and the child can become a late enrollee, even though coverage was automatic at birth. Memorize that automatic newborn coverage and the notification deadline are two separate rules that work together.
Under a group health plan, which party holds the master policy and which document does a covered employee receive?
An employee returns to work for the first time on the day group coverage is scheduled to take effect, but a coworker is home sick that day. Which provision may delay the sick coworker's coverage?
