Stop-Loss Renewal Starts Now. Not in October.

The Market Isn't Waiting for You

Average top-tier stop-loss claims hit $6,609,798 in 2024, according to the Voya Stop Loss Insurance Paid Claims Analysis 2025. That number is up roughly 6% from 2023. Claims over $5 million keep rising year-over-year. Premature infants remain the most common diagnosis driver in Voya's book of business. These aren't outliers anymore. They're the baseline.

According to Meridian Risk Management, 2026 is shaping up to be a more complex, data-driven, and expensive stop-loss market. If you're planning to start your January 1 renewal in October, you're already behind.

Why 90 Days Is the Minimum

Most employers treat stop-loss renewal like a 30-day fire drill. Broker submits a spreadsheet, three carriers respond, you pick one. Done.

That process made sense when claims were manageable and carriers competed aggressively. It doesn't work when a single claimant can cost $6 million and the market is tightening. You need time to stress-test attachment points, model trend scenarios, and negotiate with data, not deadlines.

The NAIC's Stop Loss Insurance, Self-Funding and the ACA report makes clear that stop-loss products aren't generally required to conform to state or federal health insurance law, including the ACA. That regulatory gap puts the burden squarely on you, the employer, to know what you're buying. You can't do that in 30 days.

The Week-by-Week Playbook

This is built for a January 1 effective date. The execution window starts the week of October 6. But the real work starts now, in July, while you still have time to fix what you find.

That's the execution window. But it only works if the pre-work is done in July and August.

July is when you pull your mid-year claims report, identify any claimants likely to breach your specific deductible, and review your current policy's laser provisions. August is when you prep the submission package and brief your broker on your risk tolerance for the coming year. Show up to October with a clean data package and a point of view. Don't let the market catch you flat-footed.

What Carriers Are Actually Looking At

Underwriters want 24 months of paid claims, large claimant detail, and your current census. They're also looking at diagnostic trends. Any employer with maternity exposure or a high-cost claimant on a biologic is going to face scrutiny.

Know your lasers before they tell you about them. A laser is a carrier's way of excluding or surcharging a known high-cost claimant. If you have open claimants near or above your specific deductible, expect laser language in your quotes. Model what that costs you before you're sitting across from a deadline.

Stop-loss is expanding into mid-market employers fast, according to Meridian Risk Management. More carriers in the market means more variation in contract language, run-in versus run-out provisions, and terminal liability terms. Read the contract, not just the premium.

Start Now or Start Behind

Voya's data covers 2.2 million employees across its stop-loss book of business. Claims are bigger, more frequent above $5 million, and climbing 6% a year. That's not a carrier problem. That's your problem, because it's your risk.

The employers who get better terms show up with clean data and a clear risk profile. They have time to negotiate because they started early. You're reading this in July. The October execution window is 13 weeks out. That's enough runway to do this right.

Pull your mid-year claims report this week. Find out what you're working with before your carrier does.
