Module 1 • Foundation for Novices
Institutional Architecture of US Public Healthcare & Fee-for-Service
To evaluate the United States Quality Payment Program (QPP), one must first understand how American public healthcare is structured. Unlike single-payer systems or direct public delivery models, the US healthcare economy is decentralized and heavily relies on Medicare. Enacted in 1965, Medicare is administered by the Centers for Medicare & Medicaid Services (CMS) under the Department of Health and Human Services (HHS).
Medicare Part A
Hospital Insurance
Funded via mandatory payroll taxes. Covers inpatient hospital care, skilled nursing facilities, home health, and hospice.
Medicare Part B
Medical Insurance (Focus of QPP)
Financed by tax revenues and beneficiary premiums. Reimburses outpatient services, doctor visits, diagnostics, and equipment.
Medicare Part C
Medicare Advantage
Capitated private insurance alternative contracting with CMS to deliver Part A and B benefits, often with extras.
Medicare Part D
Prescription Drug Benefit
Subsidized outpatient pharmaceutical coverage delivered through competing private insurers.
The Medicare Physician Fee Schedule (PFS) Formula
Reimbursement under Part B uses Relative Value Units (RVUs) multiplied by Geographic Practice Cost Indices (GPCI) and a national Conversion Factor (CF).
National Conversion Factor (CF): $32.35Calculated Payment: $90.58
Perverse Incentive of FFS: Revenue equals billing volume and procedural complexity. Clinicians were rewarded for ordering extra diagnostic panels, while care coordination and prevention yielded minimal compensation.
The Sustainable Growth Rate (SGR) Crisis
Enacted in 1997 to control Part B spending, the SGR formula tied annual physician expenditure targets to national GDP growth. If claims exceeded targets, SGR mandated automatic across-the-board cuts to the Conversion Factor.
The "Doc Fix" Cycle: Because medical spending outpaced GDP, strictly enforcing SGR would trigger double-digit fee cuts, threatening practice closures. Between 2003 and 2015, Congress intervened 17 times with temporary stopgap legislation ("Doc Fixes") to override cuts, accumulating huge deficits.
Key Takeaway for Novices:
The failure of SGR proved that spending cannot be controlled by administrative rate cuts alone without reforming the underlying fee-for-service volume incentive. This set the stage for MACRA in 2015.
Module 2 • Legislative Paradigm Shift
MACRA 2015 & The QPP Dual-Track Architecture
Passed with bipartisan majorities, the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) permanently repealed the SGR formula and established the Quality Payment Program (QPP). QPP formally links Medicare Part B clinician reimbursement to clinical quality, health IT adoption, process improvement, and resource efficiency.
Default Track
Track 1: MIPS
Merit-based Incentive Payment System
For clinicians remaining in traditional fee-for-service. Consolidates legacy programs into a single 0-100 score that adjusts Part B claims upward or downward two years later.
Acts as a regulatory reporting baseline for independent practices.
High-Value Track
Track 2: Advanced APMs
Advanced Alternative Payment Models
For integrated networks bearing financial risk for total care costs (e.g., ACOs). Exempts providers from MIPS reporting and grants preferential updates.
🌟 Exemption: Bypasses MIPS administrative burden
🌟 Historical Bonus: 5.0% to 1.88% lump-sum bonus
🌟 CF Spread (2026+): Permanent +0.75% vs +0.25% update
Strategic mechanism for systemic healthcare transformation.
Strategic Incentive Pathway: Moving Clinicians Up the Value Curve
Traditional Fee-for-Service
Unadjusted PFS Payments
High volume risk, zero quality alignment. Driven by RVUs.
MIPS evaluates clinicians across four statutory performance categories, yielding a Composite Score (0–100 points). This score determines payment adjustments applied to Medicare Part B claims two calendar years later.
MIPS Category Statutory Weights
*Categories can be dynamically reweighted by CMS for small practices or exceptions.
Adjust category performance scores below to calculate your estimated composite score and projected payment adjustment.
Calculated Final Score:
81.25 / 100
Performance Threshold: 75.0 pts
Projected Part B Adjustment:
+0.75%
Positive Adjustment (Scaled)
Budget Neutrality Constraint: Statutory ceiling is +9.0%, but MIPS is a closed loop. Positive bonuses are funded exclusively by penalties collected from clinicians scoring below 75 points. Because most clinicians score >75, actual positive adjustments are compressed to +0.5% – +2.0%.
Evolution: MIPS Value Pathways (MVPs)
Traditional MIPS was criticized for "measure gaming"—allowing clinics to pick 6 unrelated metrics from a menu of 200+. In response, CMS created MVPs: pre-selected, clinically connected subsets of quality, cost, and improvement measures focused on specific medical specialties or health conditions (e.g., Cardiology, Oncology, Chronic Kidney Disease).
1. Clinical Relevance
Eliminates cherry-picking by tying metrics directly to patient condition pathways.
2. Cross-Domain Alignment
Integrates Quality, Cost, and Health IT into unified condition care bundles.
3. Bridge to APMs
Prepares independent practices to assume two-sided financial risk in APMs.
Module 4 • Risk-Bearing Models
Advanced APMs, Qualifying Participants & ACO Architecture
Advanced Alternative Payment Models (Advanced APMs) transition healthcare networks from fee-for-service to population-level financial accountability.
Criterion 1
Certified Health IT (CEHRT)
At least 75% of participating clinicians in the APM entity must use Certified Electronic Health Record Technology.
Criterion 2
MIPS-Comparable Quality
Payments must be tied to quality measures comparable to MIPS, with at least one outcome-based metric.
Criterion 3
Nominal Financial Risk
Must bear downside risk equal to ≥8% of Medicare revenue or ≥3% of total expected benchmark expenditures.
Qualifying Participant (QP) Threshold Mechanics
Clinicians must pass attribution thresholds via APMs during snapshot dates to earn QP status and bypass MIPS.

One-Sided Risk: Share savings up to 40-50%, zero downside liability (Not Advanced APM).
Two-Sided Risk: Share up to 75% savings, but must repay 40-75% of losses if benchmark exceeded (Qualifies as Advanced APM).
ACO REACH (CMMI Innovation Model)
Advanced model focusing on health equity and capitated payments:
Capitated Primary Care: Monthly upfront payments instead of fee-for-service claims.
Health Equity Benchmark Adjustments: Extra resources for underserved populations.
Direct Contracting Infrastructure: Evolving toward future models such as ACO LEAD.

National Registry Scoring & Payment Adjustment
Note: Multi-vendor EHR fragmentation in the US creates massive translation overhead—a pitfall Hong Kong can bypass using its centralized eHealth platform.
Despite noble intentions, empirical evaluations of MIPS reveal severe operational friction, negative return on investment, and systemic socioeconomic inequities.
$12,811
Annual Compliance Cost
Per physician per year spent navigating MIPS documentation, IT systems, and registry reporting (Khullar et al., JAMA).
201.7 Hours
Staff Burden Per Doctor
Time spent annually by physicians, administrative staff, and IT specialists handling checklists (54% direct physician time).
-$8,000+
Net ROI Disparity
Average MIPS positive bonus is only $300–$4,000, creating a severe negative net financial return for most clinics.
Complying with MIPS costs vastly more than the maximum budget-neutral bonuses awarded.
⚠️
MedPAC Recommendation: Repeal MIPS Completely
The Medicare Payment Advisory Commission (MedPAC)—the independent congressional advisory agency—formally recommended that Congress repeal MIPS entirely due to four fundamental design flaws:
1. Statistical Unreliability
Individual doctor patient sample sizes are too small for accurate quality/cost measurement.
2. Metric Gaming & Score Inflation
Clinicians self-select high-scoring menu items, masking true variations in care quality.
3. Process Checklists vs Outcomes
Rewards administrative box-checking rather than population outcome improvements.
4. Zero Transparency for Consumers
Scores show no statistically significant correlation with patient clinical outcomes.
MedPAC's Proposed Alternative: The Voluntary Value Program (VVP)
Abolish individual doctor reporting. Withhold 2% of fee-for-service claims automatically. Allow doctors to earn it back ONLY by joining integrated clinician groups evaluated collectively using population-level claims data (e.g., avoidable hospitalizations, mortality).

Module 8 • Policy Action Plan
Strategic Recommendations for the Hong Kong SAR Government
By distilling lessons from US QPP failures and successes, the Health Bureau, PHC Commission, and Strategic Purchasing Office can design a world-class Value-Based Care framework for Hong Kong.
1
Avoid Fee-for-Service Micro-Measurement Burden
US Lesson: MIPS spent $12,811 and 201 hours per doctor annually measuring 200+ process checklists without improving health outcomes. HK Action: Hong Kong primary care consists mostly of solo practitioners. The SPO should forgo micro-process reporting and focus strictly on 4-5 core clinical outcomes (e.g., Blood Pressure control, HbA1c < 7.0%, annual kidney screening, avoidable hospitalizations).
2
Capitalize on Centralized eHealth Infrastructure
US Lesson: US clinics struggle with hundreds of incompatible EHRs requiring costly translation standards (QRDA/HL7). HK Action: Leverage Hong Kong’s centralized eHealth platform. Embed native quality tracking tools directly into eHealth so that routine clinical data (prescriptions, BP readings, lab orders) automatically calculate quality metrics without doctors filling extra forms.
3
Adjust Quality & Cost Benchmarks for Socioeconomic Risk
US Lesson: Unadjusted MIPS metrics penalized safety-net providers, causing a "Reverse Robin Hood" wealth transfer to rich hospital systems. HK Action: When rewarding family doctors in CDCC, incorporate a Complex Patient Bonus or risk-adjusted target tiers for clinics operating in lower-income districts (e.g., Sham Shui Po, Kwun Tong) to prevent penalizing clinics treating high-risk patients.
4
Transition from Fee-for-Service Subsidies to Capitated Bundles
US Lesson: Marginal claims tweaks under MIPS failed to change behavior, whereas capitated shared-risk models (ACOs) drove real efficiency. HK Action: Evolve CDCC from visit-based subsidies (HK$166/visit) into annual risk-adjusted primary care capitation bundles contracted with physician networks or District Health Centre clusters.
5
Align Primary Care Incentives with Public Hospital Decompression
US Lesson: Success in value-based care requires aligning financial rewards across the entire care continuum. HK Action: Direct primary care incentive pools toward public hospital decompression metrics. Reward physician groups that achieve verifiable reductions in avoidable A&E attendances and acute bed-days for chronic condition flare-ups.
The Ultimate Strategic Goal for Hong Kong
By combining the efficiency of single-payer centralized health IT (eHealth) with population capitation incentives, Hong Kong can build a high-performing primary care gatekeeping system that relieves Hospital Authority pressure and ensures long-term healthcare sustainability.
