Your Employees Can See Real International Procedure Prices and Book Directly
The same procedures driving your plan's highest claims cost 50-80% less at accredited international hospitals. Sylk Health shows your employees those prices and lets them book consultations directly. It costs your plan nothing.
44% of large employers already cover medical travel. 92% run at least one COE programme. But most of them are doing it with spreadsheets, broker emails, and ad hoc reimbursement. Sylk Health is one of the few marketplaces where international providers publish real procedure prices. And it's the only one that doesn't charge employers a dime.

About Sylk Health's role. Sylk Health operates a directory and booking-infrastructure layer. We list JCI or equivalent nationally accredited international hospitals and transmit consultation booking requests between patients and providers. That is the extent of our service. Sylk Health does not provide medical care, clinical advice, or treatment recommendations. All healthcare providers listed on the Sylk Health marketplace are independent. Patients who book a consultation through Sylk Health contract directly with the treating provider. Clinical decisions, treatment outcomes, and the standard of care delivered are the sole responsibility of the treating provider. Sylk Health does not select, rank, or recommend specific providers.

Employer Health Plan Costs Are Rising Faster Than at Any Point in 15 Years
RAND's 2024 Hospital Price Transparency Study found that employers and private insurers paid hospitals an average of 254% of what Medicare would have paid for the same services. In some states, it's over 300%.
That premium isn't buying better outcomes. The Commonwealth Fund's Mirror Mirror 2024 report ranks the US last among 10 high-income nations on health system performance, despite spending nearly double the OECD average. But here's the thing: the US ranks second in clinical care process quality. The problem is price and access. Not capability.
$18,500
Average annual health benefit cost per employee (Mercer, 2025)
6.7%
Year-on-year increase, steepest since 2011
28%
Of total plan costs driven by top 1% of members (WTW, 2025)
How Much Do Employers Pay for Health Insurance in 2026?
According to Mercer's 2025 National Survey, average total health benefit cost per employee is crossing $18,500 per year. That's a 6.7% increase, the steepest since 2011. The Milliman Medical Index puts total healthcare cost for a family of four at $35,119 in 2025. Nearly triple what it was two decades ago.
Where the Spending Concentrates
That cost isn't spread evenly. Willis Towers Watson's 2025 Best Practices in Healthcare Survey (417 employers, 5 million employees) found the top 1% of plan members drive roughly 28% of total plan costs. AHRQ's Medical Expenditure Panel Survey puts it sharper: the top 5% of spenders account for 49.7% of all healthcare expenditures, with top-1% spenders averaging $147,071 per year.
For a self-funded employer with 1,000 lives, that means 8 to 12 high-cost cases per year can represent 20-30% of total claims. Knee replacements. Spinal fusions. Cardiac bypass. Bariatric surgery. These are the procedures that move the needle on plan performance.
Why Domestic Cost-Containment Has Plateaued
Reference-based pricing generates friction with providers. Narrow networks generate friction with employees. Surgical bundling reduces the unit cost but doesn't touch the pricing dynamic underneath: US hospitals charge multiples of what JCI-accredited international hospitals list for the same work.
About half of US metropolitan areas are served by one or two health systems for all inpatient commercial hospital care (Peterson-KFF). That concentration is why the RAND 254% figure exists. Negotiating harder with a local monopoly doesn't change the math.
The 2024 iFHP International Healthcare Cost Comparison Report makes it concrete. Median coronary bypass surgery cost in the US: $89,094. In Australia: $17,741. In Spain: $10,734.
The math is structural. For self-funded employers evaluating healthcare cost containment, international price data offers something domestic negotiation can't: a completely different cost basis.
How Walmart Centers of Excellence and Domestic COE Programs Work
This isn't new. According to the Business Group on Health's 2024 survey, 92% of large employers have adopted at least one type of COE. Walmart, Lowe's, McKesson, GE, Boeing, and JetBlue all route employees to designated domestic providers for high-cost procedures.
Elizabeth Mitchell, President of the Purchaser Business Group on Health (representing ~40 employers spending $350B annually): "Getting access to price and quality data to effectively evaluate whether employers and families are paying a fair price for health care services is still too hard."
She's right. And that's the gap.
What Peer-Reviewed Research Shows
Whaley et al. (Health Affairs, 2021) studied 2,372 procedures across 8 self-insured employers between 2016 and 2020. They found an average $4,229 reduction in episode price (10.7%), with spinal fusion savings of 29.1% ($29,164 per episode) and joint replacement savings of 18.4%. For every $1 in copayments waived, employers saved $7. Thirty percent of referred patients received recommendations for conservative treatment instead of surgery.
That's published in Health Affairs, the top health policy journal in the country. Peer-reviewed. RAND-authored.
Walmart COE Programme Outcomes
Walmart's programme routes employees to designated hospitals for spine surgery, joint replacement, and cardiac care. Travel and lodging covered. Voluntary. Launched in 2013.
According to Woods, Slotkin, and Coleman writing in Harvard Business Review (March 2019): 95% reduction in 30-day readmission rates for spine surgery (3 per 1,000 at COE sites versus 65 per 1,000 elsewhere), 2.6 weeks faster return to work, and 70% lower readmission rates for joint replacements. Of roughly 2,300 employees referred for spine evaluation, 54% received non-surgical treatment.
Lowe's and PBGH Coalition Results
Lowe's reported 700+ employees used its COE programme with 20-30% cost reduction versus prior bundled rates, with roughly 30% of surgical candidates redirected to conservative care.
An Honest Counterpoint
A 2013 study by Mehrotra et al. in Medical Care, analysing over 85,000 spinal procedures across 369 insurer-designated COEs, found no significant differences in complication rates, readmission rates, or costs. But that study evaluated the older volume-based model. The employer-directed bundled-payment model with second-opinion gatekeeping that Whaley et al. studied in 2021 is a different approach entirely. That's the one producing the results above.
Where Sylk Health Fits
44% of large employers already offer at least one medical travel benefit (Mercer, 2022 survey of 701 organisations). But most of them are running it with ad hoc reimbursement accounts, finding hospitals on their own, verifying accreditation themselves, negotiating over email.
Sylk Health lists what they've been doing manually: published pricing from JCI-accredited and equivalent nationally accredited providers, a 1,954-procedure searchable catalogue with US and international pricing side by side, direct booking, zero integration burden.
Employees search providers, compare published prices, and book consultations directly. It's a voluntary, self-service model. Sylk Health doesn't manage episodes of care, negotiate bundled payments, or oversee clinical quality.
Where domestic COE programmes reduce per-procedure cost by 15-30% versus general in-network pricing, JCI-accredited international providers on Sylk Health's directory list prices at substantially deeper differentials for the same procedures. The numbers are visible on the marketplace before you talk to anyone.
And here's the competitive reality: as of April 2026, Sylk Health is one of the few directories in this category that publishes real, procedure-level pricing from accredited international providers. Every competitor asks you to call for a quote. We publish the prices.
ERISA Fiduciary Context
Stern v. JPMorgan (2026) confirmed that plan design choices are settlor functions, not fiduciary acts. Cunningham v. Cornell (2025) shifted the burden: defendants must now prove fees are reasonable. The DOL's FAB 2026-01 put it plainly: "ERISA is a law of process, not results."
Employers who document that they evaluated pricing alternatives demonstrate the procedural diligence ERISA requires. International pricing data is one input for that evaluation.
Regulatory context only. Not legal advice. Consult your ERISA counsel.
How It Fits Your Existing Benefits Stack
Sylk Health isn't replacing your domestic network, your TPA, your PBM, or your existing COE programme. It's one more resource your plan makes available to employees.
No TPA Renegotiation Required
Adding the directory requires no changes to your existing benefits administration workflow. None.
What Stays the Same
No eligibility file exchange. Sylk Health doesn't receive your census, your eligibility file, or your member roster. Employees access the directory directly. Sylk never knows who's enrolled in your plan.
Minimal data footprint. Sylk Health collects an email address and an auto-assigned ID. No names, no demographics, no medical history, no insurance information. No BAA required.
No technology integration. No API connections, no SSO, no data feeds. Standard web browser.
No TPA renegotiation. International claims can be processed through your existing out-of-network or COE reimbursement pathway.
Zero cost to the plan. Sylk Health is paid by providers on completed treatment. No platform fee, subscription, or per-member charge.
What Your Plan Gains
Employees get access to a directory of JCI-accredited international providers with published pricing for 1,954 procedures. Your plan gets a documented international pricing reference point for high-cost procedures. And employees who opt in and complete treatment internationally may generate measurable plan savings, depending on utilisation and provider pricing.
That's it. No months-long implementation. No vendor management overhead. No system migration.
Who This Works For: Self-Funded Employers, 500-5,000 Employees
This page is for VP Benefits, CFOs, and benefits consultants at self-funded US employers with 500 to 5,000 employees. It isn't for everyone.
Strongest Fit
Self-funded plans, 500-5,000 employees. Large enough to have a meaningful number of high-cost procedures per year. Small enough that each case visibly moves plan performance.
Employers already running domestic COE programmes. The procurement framework, employee communication model, and travel-benefit infrastructure already exist. This is an additional resource, not a new capability.
ESOPs and employee-owned companies. Plan savings flow directly back to employees through improved plan economics.
Employers with a distributed or remote workforce. Employees already travel for domestic COE procedures. International travel is a smaller incremental step.
Multi-national employers with employees who have ties to specific countries. Some employees have family, language fluency, or comfort with healthcare systems abroad.
Not a Fit Today
- Fully insured plans without self-funded carve-outs
- Employers with fewer than 200 employees
- Organisations that can't amend their plan document
Implementation Timeline: About 30 Days
Review your current plan structure. Decide whether you're making the directory available as an informational resource or as a formal plan benefit.
Your ERISA counsel reviews plan-document implications. Your TPA gets notified that international claims may come through. No TPA renegotiation required.
Employee communication materials are finalised. Sylk Health's branded fact sheet gets reviewed internally. HR approves messaging.
The resource is announced to employees. They can start using the marketplace immediately. No enrolment step required.
Total implementation work on your side: one legal review, one TPA notification, one employee communication.
No technical integration. No data exchange. No system configuration.

TL;DR for Your Benefits Advisor
Forward this to your benefits advisor or ERISA counsel before the next renewal:
- Your plan may be overpaying. RAND's 2024 data shows employers pay 254% of Medicare for the same hospital services. For the six highest-cost procedure categories, JCI or equivalent nationally accredited international providers list prices at 60-85% below US commercial rates.
- The fiduciary bar just moved. DOL FAB 2026-01 says ERISA is "a law of process, not results." Documenting that you evaluated international pricing alternatives is now one of the clearest ways to show procedural diligence. Litigation is accelerating post-Cunningham v. Cornell.
- No integration burden. Sylk Health is a directory with published pricing. Minimal data footprint, no TPA renegotiation, no platform fee. International claims go through your existing out-of-network pathway.
- The COE infrastructure gap is real. 92% of large employers run a domestic COE programme. The dominant third-party administrator in this space closed in December 2025. Employers are rebuilding these programmes from spreadsheets.
- Minimal implementation burden. 30-day implementation. No cost if nobody uses it. You keep the pricing data as fiduciary documentation regardless.
Your advisor needs the RAND pricing data and the ERISA litigation trend before renewal season.
Frequently Asked Questions
12 questions self-funded employers ask about international COE directories
Making an international provider directory available to employees is a plan-design decision. Under ERISA, that's a settlor function. Settlor functions aren't subject to ERISA's fiduciary duties. The decision is structurally similar to adding a domestic COE programme or a cost-comparison tool.
After Stern v. JPMorgan and Cunningham v. Cornell, fiduciaries face increasing scrutiny on whether they're paying reasonable compensation for medical services. The DOL's FAB 2026-01 reinforces that ERISA is "a law of process, not results," and that employers who document their evaluation of pricing alternatives demonstrate the process-based diligence the statute requires.
Consult your ERISA counsel for plan-specific guidance. Sylk Health doesn't provide legal advice.
It depends on positioning. If you're making the marketplace available as an informational resource (similar to a cost-comparison tool), no amendment is required. If you want to formally recognise international care under the plan as a covered benefit, you'd need a plan-document amendment and Summary of Material Modifications. Consult your ERISA counsel.
Notify your stop-loss carrier. Most carriers cover international claims at JCI-accredited facilities, particularly when the per-case cost is substantially below the domestic equivalent. Because international procedures are typically priced well below US rates, the net effect may reduce the likelihood of hitting specific and aggregate stop-loss thresholds.
Talk to your stop-loss carrier or broker before the next renewal cycle.
All medical procedures carry risk. Employees who proceed with treatment contract directly with the treating provider. Post-treatment care is between the employee and the provider. Employees should discuss complication protocols with the provider before proceeding.
The employee's domestic plan continues to cover follow-up care according to its terms. JCI-accredited hospitals maintain clinical records that can be shared with US providers. Many patients who travel for procedures independently purchase complication coverage from third-party insurers.
Sylk Health doesn't manage complications, follow-up, or any aspect of clinical care.
HSA and FSA funds can generally be used for qualified medical expenses under IRC Section 213(d). Medical care at an accredited facility in another country can qualify. Travel costs are subject to IRS rules and limitations ($50/night lodging cap per person under current rules). Consult your tax adviser.
If international marketplace access is part of the plan document as a covered benefit, COBRA continuation applies. If it's offered as an informational resource outside the plan document, COBRA doesn't apply. Consult your ERISA counsel.
Minimal changes. International claims can be processed through your existing out-of-network or COE reimbursement pathway. No system integration, no new data feeds, no eligibility file exchange with Sylk Health. A brief notification to your TPA is sufficient.
Joint Commission International is the international arm of the Joint Commission, which accredits US hospitals. JCI evaluates hospitals against international patient safety and quality standards across more than 1,200 measurable elements. JCI-accredited hospitals undergo on-site surveys every three years. As of 2026, roughly 600 hospitals in over 70 countries hold JCI accreditation. Every provider listed on the Sylk Health marketplace holds current JCI accreditation or equivalent national accreditation.
No. Sylk Health is a directory and booking layer. Employees see published prices, wait times, and consultation availability. They compare options and choose a provider themselves. Sylk Health doesn't rank, feature, match, or recommend providers.
Nothing. Sylk Health is paid by providers on completed treatment. There's no platform fee, subscription fee, per-member fee, or implementation fee charged to the employer, plan, or employee.
Then the resource cost your plan nothing. No minimum commitment, no usage threshold, no penalty. The marketplace stays available. And you retain the pricing data as documentation that your plan conducted international pricing due diligence.
Providers upload their own pricing to the marketplace. These are the prices providers are willing to publish, not estimates or averages. Because patients see and compare prices from multiple providers for the same procedure, providers have a structural incentive to keep listed prices current and competitive. Sylk Health doesn't set, negotiate, or guarantee prices.
