Why employees choose the wrong health plan — and what it means for your ICHRA implementation

Nobel Prize-winning economist Richard Thaler has argued that people routinely choose the wrong health plan — not out of carelessness, but because of cognitive biases and plan complexity¹. That observation, made in the context of employer-sponsored plans, applies with even greater force to the individual market — where the range of options is wider and the guidance available is thinner.

In the context of Individual Coverage Health Reimbursement Arrangements (ICHRA), employee plan selection is a critical determinant of overall program success. When employees have negative experiences—unexpected out-of-pocket costs, disrupted provider relationships, or uncovered medications—they often attribute those outcomes to the employer's transition to the individual market.

Understanding how employees make plan decisions, and where those decisions break down, is essential to mitigating that risk.

The premium default: why employees choose the cheapest plan

Monthly premium is the most salient factor in plan selection for most people. It is visible, predictable, and paid regularly — whereas out-of-pocket costs are uncertain and occur in the future. Behavioral economics describes this as present bias: the systematic tendency to overweight immediate, certain costs relative to future, uncertain ones.

The result is that many individuals prioritize minimizing premiums even when doing so increases their out-of-pocket exposure. Research on employer-sponsored plan choices finds that a significant proportion of employees make "dominated" choices — selecting plans that cost more overall even though other options provide equal or better coverage². The individual market, with its greater plan variety and less employee guidance, produces the same pattern at scale.

The three hidden costs that premium shopping misses

1. The deductible gap

Individual market bronze plans typically carry deductibles of $6,000 to $8,000. Silver plans generally range from $2,000 to $4,000. The premium difference between bronze and silver in the same market is often $100 to $200 per month — or $1,200 to $2,400 annually.

For an employee who reaches their deductible in a given year — a single ER visit, or an orthopedic procedure — the $3,000 to $4,000 deductible difference between bronze and silver dwarfs the premium savings. Even for moderate healthcare users, the bronze plan is often the wrong choice.

2. The network blindspot

Most employees do not think about provider networks when selecting a health plan, particularly when they are healthy. They think about their doctor when they try to book an appointment and discover they are out of network — or when they receive an unexpected bill months after a procedure.

This is particularly acute in the individual market, where HMO and EPO plans make up a substantial portion of available options. An employee accustomed to a PPO group plan may select an HMO simply because it has a lower premium, without realizing that their specialist or hospital system is not in network. For employees with ongoing specialist relationships, chronic conditions under active management, or care at specific hospital systems, network disruption is not an inconvenience — it is a genuine clinical and financial risk.

3. The formulary gap

Health plan formularies vary significantly across individual market plans in the same market. A medication that is Tier 1 on one plan may be Tier 3 on another, require prior authorization, or be excluded entirely. For employees on maintenance medications — thyroid drugs, blood pressure medications, diabetes management, psychiatric medications, or specialty drugs — formulary differences between available plans can represent $500 to $3,000 or more in annual cost variation.

This is particularly consequential in the ICHRA context because employees entering the individual market for the first time are unlikely to know to check the formulary before enrolling.

The choice overload problem

Beyond the specific blind spots above, the individual market presents a fundamental cognitive challenge: too many options. In most metropolitan markets, a given employee may face 40 to 150 or more plan options across different metal tiers, carrier networks, and plan types. Research demonstrates that beyond a manageable range, more options reduce decision quality and increase decision regret.

Employees faced with 80 plan options do not compare them carefully. They apply simple heuristics — lowest premium, familiar carrier name, first plan listed — that are poor proxies for the right plan for their situation.

What meaningful guidance actually looks like

The antidote to premium-default shopping is not more information — it is more relevant information, presented in the context of the individual employee's actual situation. Meaningful plan guidance has four characteristics:

• Employee-centric: The guidance starts with the employee, not with the plans. Health status, provider relationships, medications, and anticipated healthcare needs must be captured before any plan recommendation is made. A recommendation built on "are you a low, medium, or high utilizer?" is not meaningfully better than the unguided default.
• Full cost modeling: The projected total annual cost — premium plus expected out-of-pocket based on the employee's health profile — must be calculated for each plan option.
• Network and formulary validation: The employee's preferred providers must be verified against each plan's network. Network size should also be considered when evaluating options. Their medications must be checked against each plan's formulary. These are not optional checks — they are one of the most consequential variables in the decision for employees with established care relationships or ongoing prescriptions.
• Clear recommendation with reasoning: The guidance should not end up with a ranked list that the employee must interpret — it should be a clear recommendation, with an explanation of why this plan is right for their situation, and an honest description of the trade-offs of choosing differently.

The employer's stake and yours

Employers who implement ICHRA without investing in employee guidance are taking on risk that is often invisible at implementation time. The most common reason ICHRA implementations fail is not that the arrangement was financially wrong for the employer. It is that employees had a bad experience in the individual market, and the employer did not provide sufficient support to prevent it.

Structured plan guidance is not a nice-to-have. For any employer that cares about workforce relations and long-term ICHRA success, it is a requirement. And for brokers and consultants, it is the part of the implementation that determines whether your client calls you in year two to say it worked — or to ask what went wrong.
