If you lead benefits for a team that’s grown past 20 employees and is considering switching from a fully insured to self-funded health plan, you’ve likely seen stop-loss insurance mentioned as a required add-on. Without this coverage, a single high-cost employee claim (like a year of specialty cancer treatment or a premature neonatal intensive care stay) could eat through your entire annual benefits budget and force cuts to other employee programs. This guide covers the most common questions growing teams have about stop-loss coverage, includes an actionable question checklist to use during your purchasing process, and flags common pitfalls to avoid.
Why this matters now: Stop-Loss Insurance: Questions Growing Teams Ask
Many growing teams switch to self-funded plans because they give more control over benefit design, allow you to only pay for the claims your team actually uses, and often come with lower administrative costs than fully insured plans. But unlike fully insured plans, where the carrier absorbs all risk for claims over the premium you pay, self-funded plans require your company to cover 100% of employee claims unless you have stop-loss insurance to cap your liability. As more small and midsize teams expand their benefits to include high-demand services like fertility treatment, gender-affirming care, and expensive specialty prescription drugs, the risk of unexpected high-cost claims has become a top concern for benefits leaders. That makes stop-loss insurance one of the most requested topics for teams scaling their health benefits offerings. Unlike core health plan coverage, stop-loss policy terms vary widely between carriers, so asking targeted questions before you buy is critical to avoiding gaps that leave your team exposed to cost overruns.
A usable checklist: Stop-Loss Insurance: Questions Growing Teams Ask
The following checklist includes the core questions to ask your benefits broker, stop-loss carrier, and third-party administrator (TPA) before you sign a stop-loss policy. You can add custom questions specific to your team’s unique benefits offerings (like coverage for remote employees living outside your home state) as needed.
☐ Do we need both specific stop-loss and aggregate stop-loss coverage? (Ask your benefits broker: specific covers single high-cost individual claims, aggregate covers total claims across your whole team crossing a yearly threshold)
☐ What is the specific deductible (also called the “attachment point”) for individual claims, and how does it align with our team’s past claims history? (Ask your TPA for 2-3 years of de-identified past claims data to compare)
☐ What is the aggregate attachment point, and is it calculated as a percentage of expected yearly claims or a flat dollar amount?
☐ Does the policy allow lasering, and if so, are there additional fees for covering pre-existing high-cost claimants? (Lasering refers to setting a higher deductible for specific employees with known ongoing high medical costs)
☐ Are there any excluded services that our core health plan covers (like specialty prescription drugs, out-of-network emergency care, or travel medical for remote employees)?
☐ Does the policy include a “run-in” or “run-out” period, and how long do those periods last? (Run-in covers claims that start before the policy effective date but are filed during the policy term; run-out covers claims that start during the policy term but are filed after it ends)
☐ What is the timeline for filing a stop-loss claim, and what documentation does the carrier require for reimbursement?
☐ Can we adjust our attachment points at renewal if our team size or claims profile changes significantly?
☐ Are there any co-insurance requirements after we hit the attachment point, and if so, what percentage of costs are we responsible for?
☐ Does the policy have a maximum annual payout limit per claim or per policy year?
☐ Will our TPA automatically submit stop-loss claims to the carrier on our behalf when a claim crosses the attachment point, or do we need to file manually?
Where people get stuck: Stop-Loss Insurance: Questions Growing Teams Ask
Most missteps with stop-loss coverage come from assuming policy terms align with your core health plan terms, rather than verifying explicitly. The first common stuck point is skipping aggregate stop-loss coverage entirely. Many teams assume only single seven-figure claims pose a risk, but a year where 10+ employees have mid-sized claims (like outpatient surgery, ongoing diabetes management, or inpatient mental health care) can push total claims far over your annual budget without any individual claim crossing a specific attachment point.
Another common pain point is misinterpreting lasering policies. Some teams assume all pre-existing conditions are covered under standard stop-loss terms, only to find out after signing that a carrier has set a 2x higher deductible for an employee with a known chronic condition, leaving the team on the hook for costs they did not budget for. Teams also frequently forget to confirm run-out coverage when switching stop-loss carriers. If you switch policies on January 1, a claim from an employee who had surgery in December may not be filed until February, and if your old policy does not include run-out coverage, you will pay that full cost out of pocket.
Illustrative example: A 75-person team has a specific stop-loss attachment point of $100k with no co-insurance. An employee has a premature birth that costs $180k total, so the team pays the first $100k, with stop-loss covering the remaining $80k. If the policy had a 10% co-insurance requirement after the attachment point, the team would pay an extra $8k on top of the $100k deductible.
What to confirm in writing: Stop-Loss Insurance: Questions Growing Teams Ask
Verbal commitments from brokers or carrier representatives are not binding, so get all of the following details in official policy documents before signing:
- Exact attachment point amounts for both specific and aggregate coverage, including any laser adjustments for individual employees listed by unique identifier (no names to protect employee privacy)
- A full list of excluded services, cross-referenced with your core health plan’s Summary of Benefits and Coverage (SBC) to flag gaps between what your health plan covers and what stop-loss will reimburse
- Exact length of run-in and run-out periods, plus any eligibility requirements for claims filed during those windows
- Clear reimbursement timelines, so you know how long it takes to receive funds after you submit a qualifying claim
- Any renewal terms, including if the carrier can raise attachment points, add laser adjustments, or deny renewal based on your prior year’s claims history
- A written confirmation of any negotiated exceptions, like a waiver of lasering for existing employees for the first year of your policy, or a cap on annual deductible increases at renewal
If any term is unclear in your policy documents, ask the carrier for a written explanation before signing, rather than relying on verbal context.

Stop-loss insurance is a critical safety net for growing teams that use self-funded health plans, and asking the right questions before you purchase a policy can help you avoid unexpected costs that derail your benefits budget. The checklist above covers the core questions most growing teams need answered, but you can add additional questions specific to your team’s benefits offerings, team size, and risk tolerance as needed. If you are unsure whether stop-loss insurance is right for your team, talk to a licensed broker who specializes in small and midsize business health benefits to compare options for your specific needs.
