How Employees Choose Coverage: Single Plan, Multi-Plan, Exchange or ICHRA
An employer can offer one plan, several plans from one carrier, a multi-carrier exchange, or an ICHRA that reimburses individual coverage. Each model trades employee choice against cost control and administrative work, and the right fit depends on group size, budget and how much risk you want to carry.
The Four Ways to Offer Coverage
Single Plan
One medical plan and one employer contribution. This is the simplest model to administer, explain and price. Employees who want a different design have no alternative, which can frustrate a workforce with mixed needs.
Multi-Plan, One Carrier
Several plan designs from one carrier, typically a richer plan, a standard plan and a high-deductible plan. Employees pick, and the employer sets a contribution toward each. The mix of plans employees choose affects how the carrier prices the group at renewal.
Multi-Carrier Exchange
A private exchange or marketplace platform lets employees choose among plans from several carriers, usually against a set employer contribution. It widens choice and moves shopping onto the platform. It also adds a vendor, platform fees and another enrollment system to manage.
ICHRA
The employer reimburses employees for individual-market premiums they choose themselves, up to a monthly allowance the employer sets. Employer cost is fixed by the allowance, not by claims or renewals. Employees shop the individual market, so networks and subsidy rules matter to them.
How the Models Differ
Employer Cost Predictability
A single plan or multi-plan offer is still priced at renewal, so cost moves with claims experience and carrier trend. An exchange or ICHRA with a fixed contribution makes the employer cost predictable, and moves the risk of rising prices to employees.
Employee Choice
Choice rises from one plan, to a few plans, to many carriers, to the whole individual market. More choice helps employees whose needs differ and adds decisions for those who want a simple answer.
Administrative Work
A single plan is the lightest. A multi-carrier exchange or ICHRA adds eligibility rules, notices, reimbursement or platform steps, and employee education, so the extra choice carries a workload cost.
Federal Rules That Shape an ICHRA
90-Day Notice
Employers generally must give eligible employees written notice at least 90 calendar days before the start of each plan year, so an ICHRA needs lead time before a January 1 start.
Classes and Same Terms
The allowance can differ by class, such as full-time, part-time, salaried, seasonal or by rating area, but it must be offered on the same terms to everyone within a class.
Mixing With a Group Plan
An employer can offer a group plan to one class and an ICHRA to another. In that case minimum class sizes apply: 10 employees where the employer has fewer than 100, 10% where it has 100 to 200, and 20 above 200.
Participants must also be allowed to opt out of the ICHRA once per plan year. Confirm the details of your situation with your benefits attorney or tax advisor.
Three Questions That Decide the Model
How Much Cost Certainty Do You Need?
If the budget must not move, a fixed contribution through an exchange or ICHRA gives that certainty. If you are comfortable with renewal swings in exchange for a richer plan, a group plan keeps more of the cost with the carrier and your claims.
How Different Are Your Employees?
A workforce with wide differences in age, location and family status gains from choice. A small, similar team often does better with one plan that is easy to explain.
How Much Administration Can You Absorb?
Each step toward more choice adds notices, eligibility rules and employee support. Employers without a benefits administrator should price that work into the decision.
Employee Choice Questions
Can I offer an ICHRA to some employees and a group plan to others?
Yes, by class of employee. The allowance must be offered on the same terms within each class, and minimum class sizes apply when you offer both a group plan and an ICHRA.
Does offering several plans raise my cost?
It can go either way. Employees who choose leaner plans can lower your cost, but the mix of plans they choose also affects how the carrier prices your group at renewal.
What is the difference between a private exchange and an ICHRA?
A private exchange is still group coverage: employees choose among plans from several carriers through a platform. An ICHRA reimburses premiums for individual-market coverage the employee buys.
How early must ICHRA notices go out?
Generally at least 90 calendar days before the plan year begins, with later timing for employees who become eligible mid-year.
