Key Takeaways
- Foundational programs are the core vendor relationships and administrative structures that every self-funded plan must have in place before layering on cost-containment strategies.
- The network, TPA, PBM, and stop-loss carrier are the four pillars — weakness in any one of them undermines the entire plan.
- Most employers inherit their foundational programs from their broker's preferred vendors rather than selecting them strategically.
- Switching foundational vendors mid-year is disruptive and expensive — get the structure right at inception or at renewal.
- The quality of your foundational programs determines the ceiling of what your cost-containment strategies can achieve.
Why Foundational Programs Matter
When employers move to self-funding, they often focus on the financial mechanics — stop-loss attachment points, claims reserves, and expected versus actual claims. What gets less attention is the vendor ecosystem that makes the plan function day to day: the network that prices claims, the TPA that processes them, the PBM that manages pharmacy, and the stop-loss carrier that backstops catastrophic exposure.
These foundational programs are not interchangeable commodities. The quality of each vendor relationship directly affects your plan's cost, your employees' experience, and your ability to implement more sophisticated strategies down the road.
Most self-funded employers are using the foundational programs their broker recommended — which are often the programs that pay the broker the most in fees, overrides, and revenue sharing. Strategic vendor selection requires understanding what each vendor earns from your plan, not just what they charge you.
A common mistake: employers switch to self-funding but keep all the same vendors they had when fully-insured — the same carrier network, the same PBM, the same care management programs. This is self-funding in name only. The financial structure changes but the cost drivers do not.
The Provider Network
The provider network is the most consequential foundational decision in a self-funded plan. The network determines what your plan pays for every medical service — through negotiated rates, fee schedules, and repricing arrangements. A weak network can cost a self-funded employer more than a fully-insured plan with a strong one.
- Rental networks: most self-funded employers access a major carrier's network (Blue Cross, Aetna, Cigna, UHC) through a rental arrangement. The employer pays a per-employee-per-month access fee.
- Independent networks: some TPAs offer proprietary networks or access to regional networks with stronger discounts in specific geographies.
- Reference-based pricing: an alternative to traditional networks that prices claims as a percentage of Medicare rates rather than negotiated discounts.
- Direct contracts: advanced employers negotiate directly with high-volume providers — hospitals, surgery centers, imaging facilities — for guaranteed rates.
When evaluating networks, ask for a network adequacy report for your specific zip codes and employee demographics — not a national adequacy statistic. A network with 95% national adequacy may have significant gaps in your specific geography. Also request the average discount percentage for your top 10 procedure codes.
Rental network fees are often buried in TPA administrative costs and not disclosed separately. Ask your TPA to itemize the network access fee as a standalone line item. Some employers are paying $15 to $25 PEPM for network access without knowing it — and without evaluating whether a competing network would deliver better discounts for less.
The "discount" a network advertises is not the same as savings. A 50% discount off a $10,000 billed charge is $5,000 paid — but if Medicare would pay $2,000 for the same service, the "discounted" rate is still 2.5 times what the market would bear. Always benchmark network rates against Medicare as the baseline.
The Third-Party Administrator (TPA)
The TPA is the operational engine of a self-funded plan. It processes claims, manages member services, provides reporting, and coordinates with the network, PBM, and stop-loss carrier. The quality of your TPA determines how efficiently your plan runs and how much visibility you have into your claims data.
- Claims processing accuracy and speed: errors and delays create member frustration and potential compliance exposure.
- Reporting capabilities: can you access real-time claims data? Can you run custom reports? Is the data exportable for analysis?
- Cost-containment program access: does the TPA have preferred relationships with cost-containment vendors, or are you free to choose your own?
- Member services: how does the TPA handle member inquiries, appeals, and disputes?
- Stop-loss coordination: how efficiently does the TPA file and track stop-loss claims?
Before selecting a TPA, ask for a live demonstration of their reporting portal — not a slide deck. Log in and run a report. Ask to see a sample monthly claims summary, a high-cost claimant report, and a pharmacy utilization report. If the reporting is clunky, limited, or requires a custom request for basic data, that TPA will limit your ability to manage costs.
Some TPAs have exclusive or preferred relationships with specific cost-containment vendors and earn revenue for steering clients to those vendors. Always ask: "Do you receive any compensation — fees, overrides, or revenue sharing — from any vendor you recommend to us?" A TPA that cannot answer this question clearly is not a trustworthy partner.
The Pharmacy Benefit Manager (PBM)
Pharmacy costs represent 20 to 30% of total plan spend for most self-funded employers — and that percentage is growing. The PBM manages the pharmacy benefit: formulary design, drug pricing, retail and mail-order pharmacy networks, and specialty drug management.
The PBM relationship is one of the most complex and opaque in the benefits ecosystem. Understanding how your PBM makes money is essential to evaluating whether their interests align with yours.
PBMs make money in ways that are not always visible to employers: spread pricing (charging the plan more than they pay the pharmacy), rebate retention (keeping a portion of manufacturer rebates), administrative fees, and network access fees. A transparent PBM passes 100% of rebates to the plan and charges a flat administrative fee. Most do not.
Request a PBM transparency audit annually. Ask for: total rebates collected versus rebates passed through to the plan, spread pricing analysis (what the PBM paid pharmacies versus what it charged the plan), and a formulary analysis showing whether preferred drugs are there because of clinical value or manufacturer rebate agreements.
Many employers are locked into PBM contracts that auto-renew with minimal notice requirements. Check your PBM contract for the termination notice period — it is often 90 to 180 days. Missing the window means another full year with a PBM that may not be serving your interests.
Stop-Loss Insurance
Stop-loss insurance is covered in depth in its own module, but as a foundational program it deserves mention here. The stop-loss carrier, attachment point, and contract terms are foundational decisions that affect every other aspect of plan management.
- Specific attachment point: the per-person threshold above which stop-loss reimburses the employer.
- Aggregate attachment point: the total plan threshold, typically set at 120 to 125% of expected claims.
- Run-in and run-out provisions: how the stop-loss contract handles claims incurred in one plan year but paid in another.
- Laser provisions: the carrier's right to exclude specific high-cost claimants from coverage at renewal.
- Terminal liability: coverage for claims incurred before termination but paid after — critical if you ever change stop-loss carriers.
Shop stop-loss every year — even if you are happy with your current carrier. The stop-loss market is competitive and rates vary significantly between carriers for the same risk profile. An annual market check keeps your carrier honest and ensures you are not overpaying for protection.
Terminal liability coverage is one of the most overlooked provisions in stop-loss contracts. If you terminate your stop-loss carrier and have a large claim that was incurred before termination but not yet paid, you may have no coverage unless your contract includes terminal liability or your new carrier provides run-in coverage. Always address this at transition.
Your Action Steps
- 1Map your current foundational vendors: network, TPA, PBM, and stop-loss carrier. Document what each costs and what each earns from your plan.
- 2Request a full compensation disclosure from your broker — all fees, commissions, overrides, and revenue sharing from every vendor they recommended.
- 3Ask your TPA to provide a live demonstration of their reporting portal and run a high-cost claimant report for the past 12 months.
- 4Request a PBM transparency report: total rebates collected, rebates passed through, and spread pricing analysis.
- 5Review your stop-loss contract for laser provisions, terminal liability coverage, and renewal notice requirements.
- 6Benchmark your network rates against Medicare for your top 10 procedure codes by paid claims volume.
