US TPA landscape and self-funded employer share

Self-funded employer plans account for approximately 60 to 65 percent of US commercial covered lives, with the share heavily concentrated in large employers. For employers with over 500 employees, self-funding is typically 80-plus percent of the covered-lives base; for employers over 5,000 employees, self-funding approaches 90 percent. Small-employer (under 100 employees) self-funding is meaningfully lower (20-30 percent) though growing through level-funded plan designs. The trend has been toward greater self-funding across the mid-market over the past decade.

TPAs administering these plans fall into two categories. First, the ASO (administrative services only) divisions of the large commercial carriers — UnitedHealthcare, Aetna, Cigna, Elevance/Anthem BCBS, and the regional BCBS state plans all operate ASO businesses that provide TPA services to self-funded employers using the carrier's provider network. Second, independent TPAs (Health Payer Systems, Meritain, HealthComp, Boon-Chapman, and regional TPAs) operate without a carrier network affiliation and typically rent access to a rented-network product or work with reference-based pricing.

TPA structure and marketing implications

The critical marketing distinction is between carrier-ASO TPA arrangements and independent TPA arrangements. A carrier-ASO plan (a self-funded employer using UnitedHealthcare as ASO with UnitedHealthcare's network) looks to the provider like the same UnitedHealthcare commercial patient — the provider sees the UnitedHealthcare network card, bills UnitedHealthcare, and the ASO-administered plan is invisible in the day-to-day claims workflow. Empanelment surfacing for these plans is the same as commercial-carrier empanelment surfacing.

An independent TPA arrangement is different. The provider sees a member card that names the TPA (Meritain, Health Payer Systems, HealthComp) rather than a commercial carrier, and the underlying network access flows through a rented-network product or through direct provider contracting. Empanelment status with the TPA — or with the rented network the TPA uses — needs to be surfaced separately from commercial-carrier empanelment. Practices in corporate-employer catchments should audit which independent TPAs administer plans covering local employers and surface TPA acceptance appropriately.

Direct-contracting funnels — employer-to-clinic direct

Direct contracting between a clinic (or a Center of Excellence) and a self-funded employer is a growing practice pattern that bypasses the TPA network intermediary entirely. The employer contracts directly with the clinic for specific services (joint replacement, cardiac procedures, bariatric surgery, oncology second-opinions) or a bundled care pathway (musculoskeletal care, cardiovascular care, complex-diagnosis navigation). Employees receive the contracted service through the direct-contract clinic without the usual TPA-network claims processing.

Marketing for direct-contract capability shifts from patient-direct marketing to employer-benefits-team B2B marketing. The audience is the HR benefits manager, the benefits consultant advising the employer, the wellness-vendor procurement lead, and the CFO evaluating the total cost of a direct-contract arrangement versus continued full network access. Content depth on outcome quality (procedure success rates, complication rates, readmission rates), cost predictability (bundled pricing), and case-management workflow (how the employee navigates the direct-contract pathway) is essential. Ichelon Consulting US's direct-contracting-capable clinic engagements build a separate employer-facing content library from the patient-facing content library.

Reference-based pricing and the network-less funnel

Reference-based pricing (RBP) is a plan design where the plan pays providers a fixed multiple of Medicare (typically 120 to 160 percent) rather than negotiating a specific network rate. RBP plans typically do not use a traditional provider network — the plan pays the reference rate to any provider the member sees, and the member may be responsible for any balance billed above the reference rate. RBP plans have grown in the small-and-mid-employer market over the past decade as a lower-cost alternative to network-based plans.

Marketing to RBP-covered patients is complex because there is no traditional network status to surface. The provider either accepts the RBP payment as sufficient (typically settling for the reference rate as payment in full) or does not accept it (balance-billing the member). Practices that accept RBP payment as sufficient should communicate that policy in patient-facing content, and practices that do not should communicate the balance-billing consequence transparently. Balance-billing surprise for RBP-plan members has been a source of consumer-complaint activity and, in some states, of state-AG action.

Direct Primary Care subscription marketing

Direct Primary Care converts insurance-covered patients into subscription cash-pay members paying a monthly or annual fee for enhanced primary-care access. DPC members typically maintain separate insurance for services outside DPC scope (specialist visits, hospitalisation, prescription drugs, imaging). Employers increasingly offer DPC as part of a self-funded plan design, with the employer paying the DPC subscription on behalf of employees as a benefit.

DPC marketing to employers requires an employer-benefits-team-scoped content library — DPC value proposition for the employer plan (predictable primary-care cost, employee-experience improvement, downstream medical-spend reduction), integration with the underlying employer plan design, and case-study content on DPC-adopting employers. DPC marketing to individual patients (for practices that also market direct-to-consumer subscription enrollment) is subscription-marketing scoped for the value-proposition-and-comparison content the member needs to evaluate.

Corporate-employer wellness-vendor procurement cycle

Corporate-employer benefits procurement operates on an annual cycle typically running spring through summer for plan-year changes taking effect January 1. Direct-contracting and DPC vendors marketing to employers should scope their B2B outreach to this cycle — outreach in April, May, and June for plan-year decisions communicated in September-October and taking effect January 1. Wellness-vendor procurement typically involves the employer's benefits consultant (Mercer, Willis Towers Watson, Aon, Segal Group, or a regional benefits consultancy) as an evaluator, and marketing that acknowledges the consultant workflow moves better than marketing that ignores it.

Empanelment vs direct-contract funnel differentiation

A clinic operating both a traditional empanelment funnel (accepting commercial carrier plans, MA plans, and self-funded TPA-administered plans through the network path) and a direct-contract funnel (contracting directly with specific employers) needs to differentiate the two funnels in creative, content, and stakeholder outreach. The empanelment funnel targets the patient searching for a provider that accepts their coverage; the direct-contract funnel targets the employer benefits stakeholder evaluating a bundled care contract. The two audiences do not overlap, and marketing that conflates them dilutes both.

Metrics for TPA-heavy marketing

TPA-heavy clinic marketing should track: bookings by TPA versus by direct commercial carrier, per-TPA CAC, direct-contract-pipeline B2B conversion (employer-outreach to signed contract), DPC subscription-conversion, RBP-plan patient volume and balance-billing complaint rate, and employer-facing content engagement (benefits-manager and CFO-scoped content). Ichelon Consulting US's corporate-employer-catchment engagements build reporting that isolates each dimension.
