Most employers who have group health insurance spend weeks comparing renewal rates. Almost none of them read the contract.
That’s a mistake that can cost millions.
I’ve spent 27 years inside this industry. I’ve helped build a PBM, an MGU and captives, and stop-loss carriers now consult me on how to word their contracts. Here’s what I’ve learned: the premium is rarely where self-funded plans get hurt. The fine print is.
Stop-loss is the insurance that protects a self-funded employer from catastrophic claims. When it’s written well, self-funding is one of the best tools a company has to control health care costs. When it’s written badly, the employer finds out at the worst possible moment: after a large claim, when it’s too late to fix.
And the ground is shifting under every employer right now:
- The insurance market is consolidating. Fewer, larger carriers and PBMs control more of the market, which means less competition and less leverage for you at the negotiating table.
- Brokerages are consolidating. Many local and regional agencies have been bought by large, often private-equity-backed firms. Your trusted broker may now answer to owners focused on revenue targets, and the way they’re paid may not line up with lowering your costs.
- Regulations are changing fast. New transparency, disclosure and fiduciary rules keep raising the bar for plan sponsors, and the responsibility for keeping up lands on you.
None of these trends are in your favor. That’s why the details in your plan and your stop-loss contract matter more today than ever.
Here are the five things I check first in every self-funded plan and stop-loss contract, and the questions every CEO, CFO and HR leader should ask before signing.
1. Forgetting that you are the fiduciary
When you self-fund, you are the plan sponsor, and under ERISA that makes you a fiduciary of the plan. That isn’t a title. It’s a legal duty to run the plan solely in the interest of your employees and their families, to pay only reasonable plan expenses, and to act with the care of a prudent expert.
Many employers assume their broker, TPA or stop-loss carrier carries that responsibility. They don’t. Those partners may be service providers to the plan, but the fiduciary duty, and the liability that comes with it, stays with the plan sponsor. Every stop-loss contract you sign, every PBM agreement and every fee you approve is a fiduciary decision.
The consequences of getting it wrong are severe:
- Personal liability. ERISA allows fiduciaries to be held personally liable to restore plan losses caused by a breach. That can reach the executives and committee members making plan decisions, not just the company.
- Penalties and excise taxes. Federal agencies can assess penalties for compliance failures, including per-day penalties for late or missing required filings and excise taxes for violations such as mental health parity failures.
- Employee lawsuits. Employees have begun suing employers over health plan costs, alleging they overpaid for prescription drugs and services because the plan wasn’t managed prudently.
- New compliance duties under the Consolidated Appropriations Act (CAA). Employers must now obtain broker and consultant compensation disclosures, attest each year that their contracts contain no prohibited “gag clauses” blocking access to cost and quality data, and be able to show that their mental health benefits comply with parity rules.
What to ask for: a stop-loss contract and service agreements that give you full access to your claims and cost data, written disclosure of every fee and form of compensation, and a documented process showing how you reviewed and approved each decision. If you can’t show your work, you can’t defend it.
2. Not knowing what your broker or consultant does every day
Ask your broker or benefits consultant a simple question: “What did you do this month to lower our health plan costs?”
If the answer is “we shopped the renewal,” you don’t have a strategy. You have an annual event. Real cost containment is year-round work, and in a self-funded plan, every dollar saved stays with your company.
Here’s what a strong advisor should be doing every day:
- Watching the claims data. Spotting large or rising claims early, before they become catastrophic, and knowing which conditions are driving your costs.
- Steering employees to world-class care. Directing members with serious conditions to centers of excellence and top specialists who get it right the first time. The goal is a cure or the right treatment, not years of ongoing, repeat costs from care that never solves the problem.
- Managing pharmacy spend. Making sure your PBM contract is transparent, generics and lower-cost alternatives are used where appropriate, and specialty drugs are reviewed instead of rubber-stamped.
- Auditing claims and contracts. Checking for billing errors, duplicate payments and overcharges, and holding every vendor to the terms you agreed to.
- Building a multi-year plan. Smoothing out volatility with the right stop-loss structure, reserves and plan design, so one bad year doesn’t wreck your budget or force you back into a fully insured plan.
Why this matters: the Rule of 72
The Rule of 72 is a simple way to see how fast something doubles. Divide 72 by the annual growth rate, and you get roughly the number of years until it doubles. Apply it to your health plan:
- 6% a year: your costs double in about 12 years
- 8% a year: about 9 years
- 10% a year: about 7 years
- 12% a year: about 6 years
If your health plan spend is $2 million today and rises 8% a year, you’ll be spending about $4 million in roughly nine years, for the same people and the same benefits. At 12% a year, it doubles in six.
No business can grow revenue that reliably just to keep up with one line item. Without a long-term strategy, the cost of health insurance isn’t a budget problem. It’s unsustainable.
What to ask for: a written, multi-year cost-containment strategy with specific actions, regular claims reviews, and clear reporting on what was saved. Then hold your advisor accountable for results, not renewals.
3. A stop-loss policy that doesn’t mirror your plan document
Your self-funded plan document says what the plan pays for. Your stop-loss policy says what the carrier reimburses. Those two documents are written by different parties, and they don’t always say the same thing.
If your plan document covers a treatment, a provider or a benefit that the stop-loss policy excludes or defines differently, your plan still owes the claim. The stop-loss carrier just won’t pay you back. Common gaps include definitions of “experimental” or “medically necessary,” eligibility rules, and how out-of-network or specialty drug claims are handled.
What to ask for: a stop-loss policy that mirrors your plan document, plus a written side-by-side review of both documents before you sign. Any time your plan document changes, the stop-loss carrier needs to approve the change in writing.
4. Disclosure requirements that let the carrier walk away
Before issuing a policy, stop-loss carriers ask the employer to disclose known large claims and ongoing high-cost conditions. Many contracts allow the carrier to deny claims, re-price the policy, or even rescind coverage if something wasn’t disclosed, sometimes even if the employer didn’t know about it.
This is one of the most dangerous clauses in a stop-loss contract, because it often isn’t tested until a large claim is filed. By then, it’s too late to renegotiate.
What to ask for: clear limits on what the carrier can do over a disclosure issue, ideally tied to what the employer actually knew. Make sure your disclosure is complete, documented and reviewed by someone on your side before it’s submitted. Ask whether the carrier has completed its underwriting review so the terms are final when you sign.
5. No cap on your renewal increase
A great first-year rate means very little if the carrier can raise it as much as it wants in year two. Without a rate cap, one bad claims year can produce a renewal so high that the employer feels forced back into a fully insured plan. That usually happens at the worst possible time, and often on worse terms than before.
This is the clause that turns self-funding from a long-term strategy into a one-year experiment.
Beware the one-year cheap play. Some carriers and advisors win business with a low first-year price, knowing the real cost shows up at renewal. A cheap year one built on thin protection, a high-risk contract basis or no renewal guarantees isn’t a savings. It’s a delay. The employers who win with self-funding treat it as a multi-year strategy, choosing the partner and contract that will still make sense in year three and year five, not just the lowest quote today.
What to ask for: a maximum renewal increase written into the contract. A rate cap gives you predictable costs from year to year, which is the reason most employers move to self-funding in the first place.
The bottom line
The health insurance system is built so the fine print favors everyone except the employer paying the bills. Self-funding changes that, but only if the stop-loss contract is written to protect the plan sponsor, which is you.
Before you sign, make sure you can answer yes to all five:
- Are we meeting our fiduciary and CAA compliance duties, and can we prove it?
- Does our broker or consultant have a written, multi-year cost-containment strategy, and are they working it every day?
- Does the stop-loss policy mirror our plan document?
- Are the disclosure terms fair, and is our disclosure complete?
- Is there a cap on our renewal increase, and protection against new lasers?
If you can’t answer yes to every one, you don’t have a stop-loss problem yet. You have one waiting to happen.
