Level Funded Pharmacy Benefits: Get Predictable Rx Costs

Medically reviewed by Jawad Arshad, MD, FACEP. Last reviewed: September 23, 2026.

Level funded pharmacy benefits give a small employer a fixed monthly prescription cost, with drug claims paid from a self-funded claims fund and big claims capped by stop-loss insurance. You find them through a level funded carrier, a third-party administrator (TPA) paired with a pharmacy benefit manager, or a transparent PBM that sells a level funded Rx product on its own.

The hard part is not finding a plan. The hard part is reading the pharmacy contract, because that is where the predictability is won or lost. Pharmacy is now about 25% of employer health spending, according to the Business Group on Health 2027 Employer Healthcare Strategy Survey, as reported by Insurance Business in August 2026.

Before you shop, see what your payroll can fund. The Summit Health Benefits Section 125 savings calculator shows the FICA savings your current employee premium deductions could produce, money many owners use to absorb pharmacy increases.

Where can I find level funded pharmacy benefit solutions with predictable costs?

Level funded pharmacy benefit solutions come from three places: a level funded medical carrier that bundles its own pharmacy benefit manager (PBM), a TPA that pairs its level funded medical plan with a PBM partner, or a transparent PBM that offers a stand-alone level funded Rx product. Predictable costs depend on the contract terms, not the vendor type.

A pharmacy benefit manager, or PBM, is the company that processes prescription claims, builds the drug list (the formulary), and negotiates rebates with drug makers. In a level funded plan, the PBM's pricing flows straight into your claims fund. Every dollar the PBM keeps is a dollar that does not come back to you as a surplus refund.

Level funding is now mainstream for small groups. Thirty-seven percent of covered workers at firms with 10 to 199 employees were in a level funded plan in 2025, according to the KFF 2025 Employer Health Benefits Survey. If you want the full mechanics of the medical side first, read our level funded health plan guide for small businesses.

How do the three sources compare?

My honest take after sitting through a lot of renewals: the bundled option is fine for a young, healthy group. Once one employee starts a specialty drug, the pass-through model usually wins.

Which companies offer top level funded pharmacy benefit programs?

The companies that offer top level funded pharmacy benefit programs fall into two camps: the large national PBMs that sit behind most level funded carriers, and smaller transparent PBMs that charge a flat fee and pass rebates back. No single company is best for every group. The right choice is the one whose contract passes the checklist below.

Summit Health Benefits does not rank vendors by brand, because brand names change hands and contract terms change every year. What stays constant is how you test them. Ask every vendor for these items in writing:

1. A drug-level claims report, at least every six months.
2. A statement that 100% of manufacturer rebates are credited to your claims fund.
3. A statement that the PBM does not use spread pricing, which is charging the plan more for a drug than the PBM pays the pharmacy.
4. Written confirmation that your stop-loss policy covers every prescription claim the PBM pays.
5. Your right to audit pharmacy claims once a year.

Transparent PBM models are gaining ground fast. Thirty-two percent of large employers will offer a transparent or next-generation PBM plan in 2027, and another 47% are considering it for 2028 or 2029, according to the Business Group on Health 2027 Employer Healthcare Strategy Survey. That is large-employer data, but small groups buy drugs at the same pharmacies and feel the same prices.

Why does the stop-loss policy matter so much for prescriptions?

The stop-loss policy matters for prescriptions because stop-loss is what caps your risk when one employee's drug costs explode. A level funded plan has two stop-loss layers: specific stop-loss, which covers one person's claims above a set amount, and aggregate stop-loss, which covers total plan claims above a set amount.

Here is the trap I see most. An employer carves pharmacy out to a cheaper outside PBM, and nobody checks whether the medical carrier's stop-loss counts those outside drug claims. If it does not, one high-cost specialty drug is no longer capped. The "savings" turn into open-ended risk.

Get the stop-loss answer in writing before you sign anything. Our guide to fully insured vs. self-funded health plans explains how stop-loss protects the claims fund in more detail.

How are GLP-1 drugs changing level funded pharmacy costs?

GLP-1 drugs are changing level funded pharmacy costs because they are expensive, widely prescribed, and used for months or years at a time. Nearly eight in 10 employers say GLP-1s are driving up their health costs, according to a Business Group on Health survey of 105 employers completed in February and March 2026.

Sixty-seven percent of those employers cover GLP-1s for weight management today. Of those, only 72% said they were likely to keep that coverage in 2027. Prescription drug spending among large employers rose 9.4% in 2025, the largest increase in a decade, according to the Mercer 2025 National Survey of Employer-Sponsored Health Plans, as reported by Insurance Business.

In a level funded plan, GLP-1 decisions show up directly in your claims fund and your renewal. Common controls include prior authorization, a required weight management program, and limiting coverage to diabetes. Our Ozempic insurance coverage guide covers the drug side in plain terms.

Which level funded pharmacy benefit providers offer the best value?

The level funded pharmacy benefit providers that offer the best value are the ones that return rebates to your claims fund and charge a flat, visible admin fee. Value is not the lowest monthly rate. Value is the lowest total cost after rebates, surplus refunds, and stop-loss protection are counted.

A Worked Example for a 30-Employee Business

The numbers below use published averages plus one clearly labeled assumption. They show how the pieces fit, not a quote.

In this example, a contract that passes rebates back to the claims fund offsets most of next year's pharmacy increase. A contract that keeps rebates offsets none of it. The monthly rate can look identical on the quote sheet.

Where Section 125 Fits

A Section 125 cafeteria plan is an IRS-approved plan that lets employees pay their share of health premiums with pre-tax dollars. Every pre-tax dollar also avoids the employer's 7.65% FICA tax, the Social Security and Medicare payroll tax, according to the IRS.

Summit Health Benefits clients typically recapture $91 to $136 per enrolled employee per month in employer FICA. After the $35 per enrolled employee per month administration fee, the net employer benefit is $56 to $101 per enrolled employee per month.

For the 30-employee example, that is $20,160 to $36,360 a year in net employer savings (30 x $56 x 12, and 30 x $101 x 12). That range is larger than the $8,392.50 pharmacy increase above. Our FICA tax savings guide walks through the math, and the Section 125 cafeteria plan guide covers setup.

What does the 2026 PBM reform law change for small employers?

The Consolidated Appropriations Act, 2026, signed into law on February 3, 2026, requires PBMs to pass 100% of rebates and related payments to ERISA group health plans and to give plan sponsors regular drug pricing reports. Most of those provisions apply to plan years beginning 30 months after enactment, which is January 1, 2029, for calendar year plans, according to Groom Law Group and Mintz analyses of the law.

Large plans, defined as 100 or more participants, get drug-level reports from the PBM every six months. Law firm analyses also note that the law treats PBMs as covered service providers under ERISA Section 408(b)(2), which means PBMs must disclose their direct and indirect compensation.

A separate Department of Labor proposed rule, released January 29, 2026, would require PBMs serving self-insured plans of any size to disclose rebates, fees, and spread pricing in dollar amounts before a contract is signed and every six months after. As of this review, the rule is still proposed, not final, according to the DOL fact sheet and a May 2026 Mintz review of public comments.

For a small level funded group, the practical move is simple. Do not wait until 2029. Ask for those protections in your 2027 contract now, while PBMs are already building the reporting.

How do I compare level funded pharmacy quotes at renewal?

You compare level funded pharmacy quotes at renewal by lining up the same five contract terms side by side, then comparing total cost after rebates. Use this checklist with your broker or TPA.

Our health insurance renewal quote checklist covers the medical side of the same renewal. If your group has higher earners, also check Section 105(h) nondiscrimination rules for level funded plans before you set employee contributions.
