Direct Primary Care and On-Site Clinics in Self-Funded Health Plan Design for 2026

The Claims Curve Begins at the Front Door

Two-thirds of covered American workers now sit inside self-funded plans — sixty-seven percent, by the Kaiser Family Foundation’s 2025 count — and the average family premium has crossed $26,993. For a plan sponsor who carries the claims risk directly, that figure is not an abstraction; it is a balance-sheet exposure that renews every year whether or not anyone intervenes. The instinct is to manage the catastrophic tail. The discipline is to also manage the front door — because the place where most members actually touch the health system, primary care, is the place where downstream claims are either prevented or set in motion. The front door is unglamorous, and it is precisely where leverage tends to hide.

What DPC and On-Site Care Actually Change

Direct Primary Care replaces the fee-for-service transaction with a fixed periodic membership: the employer pays a flat monthly fee per enrolled member, and the member gains unhurried access — longer visits, direct messaging, same-day appointments — without a claim being generated for each encounter. On-site and near-site clinics apply the same logic at a facility the employer sponsors, the near-site version shared across several nearby employers so that mid-market sponsors can reach the model without the capital of a dedicated build. The intent is identical: move routine care out of the high-cost, episodic channel and into a relationship. Monthly memberships in the market commonly run from roughly $65 to $85 per adult — a fixed, forecastable line item that behaves nothing like an open-ended claims account. The Society of Actuaries’ evaluation of a DPC population found risk-adjusted allowed claims running 12.64 percent below a matched traditional cohort, with emergency-department use roughly forty percent lower once age, gender, and health status were controlled. Fewer avoidable ED visits, fewer reflexive specialist referrals — that is where the curve bends.

The 2026 HSA Question, Finally Answered

For years a structural problem shadowed DPC: a membership arrangement looked like “other coverage,” which disqualified an employee from contributing to a Health Savings Account alongside a qualifying high-deductible plan. That ambiguity has been resolved. Under the One Big Beautiful Bill Act and the IRS guidance that followed in Notice 2026-5, a qualifying Direct Primary Care Service Arrangement no longer disqualifies HSA eligibility for months beginning after December 31, 2025. The safe harbor carries real boundaries — the arrangement must provide only primary care from primary care practitioners for a fixed fee, capped at $150 per month for an individual and $300 for a multi-person arrangement, and it cannot bundle in general-anesthesia procedures, most prescription drugs, or lab work outside the ambulatory setting. Cross those lines and the arrangement reverts to disqualifying coverage. A fiduciary-minded sponsor should treat that cap as a design constraint to engineer around, not a footnote to discover at audit.

Carve-Out Mechanics and the Weight of the Evidence

Mechanically, DPC and clinic access sit alongside the self-funded plan rather than inside the insured risk pool — a carve-out layered on top of the third-party administrator’s adjudication, with the membership or clinic cost treated as a plan expense and the HDHP left intact behind it. The evidence rewards sponsors who hold realistic expectations and punishes those who expect a turnkey miracle. The Self-Insurer has documented well-run clinics returning on the order of $1.50 for every dollar spent after three to five years, with one health-system employer reporting an eighty-percent reduction in hospital stays across its clinic population; The Alliance places total-cost-of-care reduction from clinics and DPC in the fifteen-to-thirty-percent range, typically surfacing twelve to eighteen months after launch rather than in the first quarter. Milliman’s 2026 analysis of a DPC Advantage model reaches parallel conclusions on cost deflection. None of this is instantaneous, and engagement is the hidden variable — a clinic no one visits, or a membership no one activates, bends nothing at all.

Why This Steadies the Stop-Loss and Captive Layer

The strategic payoff is not only the dollars recovered; it is the volatility removed. Primary-care-anchored designs compress the frequency of the mid-size, preventable claims that make a self-funded year swing — and a steadier claims distribution is precisely what a stop-loss contract, or a group-health captive layer, must otherwise absorb at a price. When the underlying curve is calmer, the risk transferred upward is smaller and more predictable, which illuminates itself at renewal in the specific-deductible submission and in the captive’s loss experience. That is ownership of risk rather than rental of it. At PFTN we test the fit through our four-step strategic process — Strategic Discovery to uncover the workforce and its real care patterns, Risk Assessment to quantify the exposure and the runway it buys, Solution Design to craft the carve-out and HSA interaction with intention, and Ongoing Optimization to hold the engagement that lets the model earn its place.
