Distributed Healthcare's mental model is Medicare plus Medigap, for all ages. The universal essential floor is comprehensive across categories — hospital, emergency, primary, specialty, maternity and newborn, mental health and SUD, AHQB-formulary prescriptions, preventive care at $0 cost sharing, basic dental prevention and emergency extraction, emergency vision exams, hearing screening — with cost sharing set by AHQB evidence. The regulated supplemental (standardized tiers, guaranteed issue, community-rated, AHQB-supervised) is a financial and convenience layer on the same clinical floor, and the AHQB one-way ratchet migrates supplemental benefits into the floor as unit costs fall. Payment is set centrally by AHQB.
The regulated supplemental is Medigap-like, not second-tier care: a financial and convenience enhancement on the same clinical floor. Same doctors, same AHQB standards — supplemental does not buy anyone out of the system. It carries reduced or zero point-of-care cost sharing, private rooms where available, faster elective scheduling within the same wait-time ceiling, comprehensive adult dental, vision correction, hearing aids, and premium prosthetics. Standardized tiers: plans are comparable line-for-line, Medigap-style, not a confusion market. Guaranteed-issue: no medical underwriting, no exclusions for pre-existing conditions. Community-rated: premium varies only by age and geography within statutory bands, never by health status. AHQB-supervised throughout. Estimated take-up analogous to current Medicare Medigap take-up, which is a politically familiar pattern.
Supplemental tiers are separately priced; the floor's $0-premium commitment never extends to them. And the boundary is not fixed: the AHQB one-way ratchet reviews annually whether a supplemental benefit migrates into the floor as unit cost falls or evidence strengthens. The ratchet is how competition above the floor keeps improving the floor itself.
The supplemental market exists for three reinforcing architectural reasons.
First, it carries the financial and convenience layer without inflating the federal promise. Reduced cost sharing, comprehensive adult dental, vision correction, hearing aids — and premium options like concierge access, private rooms in hospitals, brand-name pharmaceuticals where bioequivalent generics are clinically equivalent, designer eyewear, premium hearing aids with smartphone integration — need a regulated home. The supplemental provides that path on the same clinical floor, until the one-way ratchet migrates a benefit into the floor.
Second, it prevents flight to private alternatives. Without a regulated supplemental layer, high-income households that want premium options would migrate to fully-private alternatives outside the architecture. Over time this would erode the universal architecture from above — provider organizations would tier their service offerings, and public-rail coverage risks becoming "what poor people use." The supplemental tier captures premium-preference dollars within the architecture's regulatory perimeter so that the floor is what everyone uses, not what some people use because they have to.
Third, it follows the Medicare-Medigap pattern. Roughly 65 million Americans on Medicare interact with supplemental Medigap policies; the architecture is politically familiar at scale. Critics who attack supplemental as "two-tier healthcare" face the awkward fact that the existing US Medicare program already operates exactly this way and has for decades.
Coverage scope is a financial and convenience layer on the same clinical floor, in standardized tiers:
- Cost sharing: reduced or zero point-of-care cost sharing on floor services - Dental: comprehensive adult dentistry (restorative work, dentures, prosthetics, root-canal-plus-crown sequences), adult orthodontics, cosmetic procedures — beyond the floor's basic prevention and emergency extraction - Vision: vision correction — routine exams, corrective lenses, and frames — beyond the floor's emergency and disease-related exams; plus designer frames, premium lens coatings, sunglass packages - Hearing: hearing aids at standard and premium tiers (rechargeable, smartphone-integrated) — beyond the floor's hearing screening; the standing illustrative one-way-ratchet candidate - Provider tier upgrades: concierge access, longer appointment slots, specialist preferences - Hospital amenities: private rooms where available, premium meals, expanded visitor accommodations - Pharmaceutical tier: brand-name where bioequivalent generic exists at comparable clinical outcome - Long-term care: private rooms in skilled nursing, premium amenities in memory care - Fast-track scheduling: faster elective-procedure scheduling within the same wait-time ceiling
Funding mechanism: supplemental tiers are separately priced and privately purchased — never bundled with the payroll tax. Employers may fund supplemental tiers for workers as taxable compensation, with no new tax exclusion (rebuilding the employer-insurance exclusion would rebuild the distortion the architecture removes), or employees may purchase directly.
Take-up assumption: ~60-70% of workers in industries with current rich benefit packages (technology, finance, professional services) carry supplemental in early years, declining to ~30-40% as the floor proves adequate for typical needs. Industries with currently-thin benefit packages see lower take-up. Population-wide take-up: ~10-25% steady state.
- Essential floor
- Supplemental is a financial/convenience layer on the same clinical floor. Floor coverage is identical regardless of whether supplemental is purchased; the AHQB one-way ratchet reviews annually whether a supplemental benefit migrates into the floor as unit cost falls or evidence strengthens.
- Anti-cream-skimming
- Tier-4 plans cannot use targeting or pricing to attract healthy populations or exclude high-cost ones. AHQB monitors enrollment patterns.
- Medicare transition (Phase 4)
- Existing Medigap policies convert to Distributed Healthcare supplemental on equivalent terms. Continuity of coverage for Medicare beneficiaries.
- Employer-insured high-comp transition
- High-comp employer plans typically convert to floor + supplemental. Employees with current platinum coverage match or exceed their current scope under the combined architecture.
Supplemental premiums are estimated at roughly $300-500B/yr at full deployment, depending on take-up. The market is private: premiums fund the supplemental coverage delivery and never subsidize — or draw from — the basic floor.
This boundary is statutory: the supplemental market is self-funding from its own premiums and copays. A household that opts out of supplemental does not lose floor coverage and does not subsidize other households' supplemental coverage.
- No medical underwriting
- Insurers cannot ask about health status or condition history. Premiums cannot vary by health risk.
- Guaranteed issue
- All applicants accepted. No exclusions for pre-existing conditions, ever.
- Community rating with bands
- Premium variation is permitted only by age and geography, within statutory bands. No individual risk-rating, no occupation-based variation, no behavior-based variation.
- Marketing prohibition
- Plans cannot target healthy populations, exclude high-cost ones, or design benefit structures that effectively cream-skim by category (e.g., excluding mental-health-heavy regions).
- AHQB product-design authority
- Tier-4 product designs are subject to AHQB approval. Designs that would produce cream-skimming patterns are denied approval before market launch.
- Enrollment-pattern monitoring
- AHQB monitors actual enrollment patterns for emergent cream-skimming. Plans with anomalous enrollment patterns face audit and regulatory action.
The supplemental tier is the single most-attacked component of universal architectures because it's the place where private-insurance-style cream-skimming could re-enter. The architecture's anti-cream-skimming rules are explicit and enforceable.
Supplemental coverage is regulated but not standardized — diversity of options is the architectural intent. Quality assurance focuses on (a) accurate disclosure of coverage scope, (b) network-adequacy requirements where the supplemental claims premium provider access, and (c) AHQB oversight of plan design to prevent fraud and cream-skimming.
The architecture's commitment is that supplemental coverage cannot degrade the floor. A patient on the floor receives identical clinical care to a patient with supplemental — supplemental adds amenities and optionality but does not change the underlying clinical standard.
Existing private-insurance workforce has the most natural transition path through supplemental. The architecture preserves a regulated private market for supplemental products; insurance carriers, brokers, and benefit consultants who today serve the employer-sponsored private-coverage market can pivot to supplemental sales and administration.
The transition is not full preservation of the current insurance industry — claims-processing, prior-authorization, and network-management roles substantially diminish because the floor architecture absorbs that work — but supplemental provides a continued role for the customer-facing elements of the existing private-insurance industry.
From the patient's perspective, supplemental is a separate enrollment decision: opt in or not, choose among approved plans, receive a separate identification and benefits package. The patient interacts with their primary-care provider on the same terms regardless of supplemental status; the supplemental coverage applies when the patient elects premium options (private hospital room, brand-name medication where generic is clinically equivalent, etc.).
For households transitioning from current high-end employer coverage, the supplemental layer typically replicates or expands their current scope. The household's net cost is comparable: supplemental withholding (~10% additional) replaces the employer/employee premium contribution they currently pay for premium employer coverage.
Supplemental coverage creates a two-tier healthcare system regardless of the architecture's intent. Wealthy households will buy premium access; poor households will use the floor. Over time the floor's quality will degrade because the political constituency for floor improvement will be the population that uses it — which is the politically weaker population.
The Medicare-Medigap pattern has operated for ~50 years without producing the degradation pattern this objection predicts. Medicare beneficiaries with Medigap and beneficiaries without Medigap receive identical hospital and physician care; Medigap covers cost-sharing and amenity gaps, not clinical care quality.
The architecture's anti-cream-skimming rules and AHQB oversight prevent the failure modes the objection cites. Supplemental cannot use targeting, cannot exclude high-cost populations, cannot offer benefit designs that effectively segment risk. The floor's clinical quality is enforced by AHQB independent of supplemental enrollment patterns.
Crucially, the political-constituency concern points the other direction. The architecture's universal-floor design — every adult enrolled, comprehensive coverage across categories, AHQB-calibrated cost-sharing — creates a political constituency at scale that the current US system lacks. The floor's political constituency is everyone, not just the poor. That constituency strengthens floor coverage over time, not weakens it.
Honesty about gaps. Distributed Healthcare has more unresolved specification than other Engines because operational complexity is higher; the items below are flagged for v10.2 specification or for outside expert review.
- Statutory band specifications for community rating: the exact age-band and geography-band ratios are pending v10.2.
- Network-adequacy requirements for supplemental plans claiming premium provider access: pending v10.2.
- Treatment of high-deductible-plus-HSA arrangements that some current employer-sponsored plans use: how these convert to supplemental at the transition is pending.
