If your company self-funds its health plan, you already know something most employers never have to learn: your claims are not an insurance premium. They are your money. Which is why a wellness program for self-insured employers is a different evaluation than it is for everyone else. A fully insured company that bends the claims curve is mostly doing its carrier a favor until renewal. A self-insured company that bends the claims curve keeps the difference.
That should make self-funded employers the most enthusiastic wellness buyers in the market. Mostly, they are the most burned. They have bought the challenges, the portals, the points programs, and watched the same 20 percent of already-healthy employees collect the rewards while the population driving the claims never logged in. This guide walks through the structure that changes that math: what it is, how it sits under a self-funded plan, and what it does to your P&L before a single claim is avoided.
Two different meanings of “self-insured,” and why the collision matters
First, a terminology collision worth clearing up, because it will come up the moment your benefits counsel looks at this.
Your health plan is self-insured: you pay claims from company assets, usually with stop-loss coverage above an attachment point, instead of paying a carrier a fixed premium.
The wellness structure described here also uses the word. It runs on a SIMRP, a self-insured medical reimbursement plan, governed by Treasury Regulation Section 1.105-11. In that phrase, “self-insured” just means the reimbursement plan is employer-sponsored rather than an insurance policy. It is the same Section 105 family your HRA grew out of.
The two are unrelated legal facts that happen to share an adjective. You do not need to be a self-insured employer to sponsor a SIMRP, and sponsoring one does not touch how your medical plan is funded. But if you are self-funded, the combination is unusually good, for reasons that are structural, not motivational.
How the structure works under a self-funded plan
The program is a three-part stack, and none of it replaces anything you have.
A Section 125 cafeteria plan lets employees make pre-tax contributions toward qualified preventive care. Taxable wages drop, so FICA drops, for the employee and for your matching share. A Preventive Care Management Program (PCMP) supplies the actual preventive care that qualifies as Section 213(d) medical expense; in Alively’s program that is run by our compliance partner, with a decade of experience doing this at scale. The SIMRP sits between them, reimbursing employees for those substantiated expenses through payroll. Alively’s own role is the engagement layer, the app and the wearable that get people participating.
Structurally, it sits below your existing benefits stack the same way an FSA or HSA does. Your self-funded medical plan, your TPA, your stop-loss contract, your existing wellness or EAP vendors: none of them move. Eligibility runs on full-time W-2 employees with qualifying major medical, and coverage under your self-funded plan qualifies the same way a fully insured plan would. Implementation is four to six weeks, roughly three hours of total HR, benefits, and payroll time, mostly around payroll line-item setup.
The economics: funded before it ever touches claims
Here is where most wellness pitches go soft, so let me be precise.
Per enrolled employee, the employer’s FICA match is no longer owed on the pre-tax election. Net of the $36 per month platform contribution, the current single-employee illustration comes to $811.89 per year, and the planning figure is more than $750 per enrolled employee per year, modeled against your actual census, at $0 capital outlay. Not budget-neutral. Positive. The line-by-line math is here.
Each enrolled employee comes out ahead on take-home pay, about $108 per month in the $39,000 worked example, and receives the platform and program benefits at no out-of-pocket cost, inside a documented benefit program.
Notice what that number does not depend on. It does not depend on claims reduction, participation streaks, health-outcome improvement, or any actuarial projection. It is payroll-tax arithmetic. For a CFO who has been promised wellness ROI before, that distinction is the whole point: the program is P&L-positive by construction, and any claims impact is upside on top of a number that already cleared.
Why self-insured employers capture the upside twice
Now the part that is specific to you.
Roughly 80 percent of healthcare spending flows to chronic conditions that public-health research treats as preventable or reversible through earlier behavior and lifestyle change. Under a self-funded plan, that spending is not an abstraction inside someone else’s loss ratio. It is your claims file. Whenever a member’s health holds instead of sliding into the high-cost band, the difference shows up on your side of the ledger, not the carrier’s. The federal government’s own prevention math, roughly $1 invested to avoid $30 in downstream sick spend, is the same bet you are implicitly making every plan year. Self-funding just means you are the one who collects when it pays off.
The catch, and there is one, is that prevention only reaches the people who engage. Traditional programs engage the 20 percent who were already at the gym. The frozen 80 percent who never engage are the same population where the preventable claims live. That is the design problem Alively exists for: one small daily action per person, wearable data onboard, built for the people who have never opened a wellness portal in their lives.
So a self-insured employer is positioned to benefit twice. Once immediately, through the modeled net payroll-tax efficiency of more than $750 per enrolled employee per year. And once over time, if the population that drives your claims finally engages with preventive care, because under self-funding any improvement in claims trend accrues to you. The second is a position, not a promise; no honest vendor guarantees a claims outcome. Fully insured employers get the first. You are positioned for both.
What your counsel will ask, and what exists to answer it
Any structure that touches Section 125 and payroll deserves scrutiny, and self-funded employers tend to have sharp benefits counsel. Good. The scrutiny is the point.
The short version: the IRS has challenged wellness arrangements that pay cash without substantiated medical expenses, route wages in a circle, or dress fixed-indemnity insurance up as reimbursement. A properly built program is structured to pass exactly the tests those rulings define, with substantiated 213(d) expenses, no automatic return of funds, and Section 125 nondiscrimination compliance. Our partner’s structure travels with a legal opinion letter, an independent CPA opinion, and a peer-reviewed CPA Journal treatment of the SIMRP structure, all available for counsel review, and participating employers are indemnified against audit exposure related to the program.
Send those documents to your counsel before you send them a deck. That order of operations is how this conversation should go.
Frequently asked questions
Does a Section 125 wellness program work if our health plan is self-funded?
Yes. The structure runs alongside your medical plan and does not depend on how it is funded. Coverage under a self-funded major medical plan satisfies the eligibility requirement the same way fully insured coverage does.
Will this disrupt our TPA or stop-loss arrangement?
No. The program is additive and sits below the existing benefits stack the way an FSA or HSA does. Your TPA relationship, stop-loss contract, and existing wellness or carrier programs stay in place.
How does a wellness program for self-insured employers pay for itself?
Pre-tax employee contributions toward qualified preventive care lower taxable wages, which removes the employer FICA match on the elected amount. After the $36 per month platform contribution, the modeled net is more than $750 per enrolled employee per year, at $0 capital outlay.
Why should self-insured employers care more about prevention than fully insured ones?
Because they keep the savings. Under self-funding, avoided claims accrue directly to the employer rather than to a carrier’s loss ratio, so a program that reaches the 80 percent of employees driving preventable claims pays the employer on both the tax side and the claims side.
