US Health Market, Decoded
A Practical Glossary for Israeli Founders Last Updated: December 2025Getting Started: How US Healthcare Actually Works
The U.S. healthcare system is enormous, fragmented, and financially driven. Clinical value matters, but alone it rarely wins. Buyers think in terms of reimbursement, workflow, incentives, evidence, compliance, and risk. Understanding the language : the terms payers, providers, and regulators use to justify decisions : is essential to selling into the system.
This glossary translates core concepts into operational knowledge: who pays for what, how reimbursement actually works, how health systems buy technology, and what evidence is needed to unlock coverage. Use it to frame your product’s value, design the right integrations, price correctly, build the right regulatory path, and avoid common mistakes that slow or kill deals.

The U.S. Health System Landscape
Payer▶
Providers▶
Regulators▶
Intermediaries
Entities that influence access, pricing, contracting, and adoption – often more than the buyer you think you’re selling to. examples:
PBMs (Pharmacy Benefit Managers)▶
TPAs (Third-Party Administrators)▶
GPOs (Group Purchasing Organizations)▶
Benefits Consultants / Benefits Brokers▶
Advisors hired by self-insured employers to design benefits, evaluate vendors, run RFPs, negotiate pricing, and manage compliance. Consultants heavily influence employer decisions and act as curators of which digital health solutions are even considered.
Network Administrators (Network Management Teams)▶
Insurance Models
Fully-Insured vs. Self-Insured▶
ASO (Administrative Services Only)▶
Stop-Loss Insurance▶
Sales Cycle▶
02
Payers & Payment Models
Fee-for-Service (FFS)▶
Value-Based Care (VBC)▶
Upside vs. Downside Risk▶
● Downside risk: Providers must repay losses if they overspend.
● Downside risk = strong buyers; urgent need for ROI-positive tools.
Founders should target organizations with real financial risk exposure.
Bundled Payments▶
Capitation / Global Budget▶
Medicare▶
Medicare Advantage (MA)▶
Risk Adjustment / HCC Coding▶
Medicaid & Managed Medicaid▶
Self-Insured Employers▶
Fully-Insured Employers▶
Stop-Loss Insurance▶
03
Payment and Risk Mechanisms
3.1 Coding Systems
ICD-10-CM (Diagnosis Codes)▶
CPT Codes (Category I, II, III)▶
● Category I = established, broadly reimbursed services
● Category II = quality tracking (not paid)
● Category III = emerging technologies with optional reimbursement
WARNING for founders:
● Getting a new CPT code takes 18–24 months, requires extensive clinical evidence, and approval is not guaranteed.
● Most startups should align with existing codes (e.g., RTM, CCM, psychotherapy, RPM) instead of relying on a future Category I code.
HCPCS Level II & J-Codes▶
Place of Service (POS) Codes▶
Modifiers (e.g., 25, 59, 95)▶
RVUs (Relative Value Units)▶
3.2 Key Reimbursement Mechanisms
DRG (Diagnosis-Related Group)▶
APC (Ambulatory Payment Classification)▶
DMEPOS▶
Buy-and-Bill▶
Prior Authorization (PA)▶
Step Therapy▶
3.3 Remote Monitoring Codes
RPM and RTM are large sources of confusion and are crucial for many digital health billing models.
RPM – Remote Physiologic Monitoring▶
● Requires device transmission of physiologic data
● Requires 16+ days of readings per month for certain codes
● Requires “incident-to” supervision rules depending on state
RPM is often not a fit for software-only startups or apps without FDA-cleared devices.
RTM – Remote Therapeutic Monitoring▶
● Can rely on patient-reported or software-collected data
● Applies to behavioral, MSK, respiratory, and adherence solutions
● Great fit for many “digital therapeutic” or “app-first” models
RTM is one of the most important developments for digital health startups in the last 5 years.
Code Stacking▶
CPT Code Creation Cycle (Warning)▶
● Expensive (studies + health economic evaluations)
● Slow
● Not appropriate for early-stage startups
Founders should build GTM around existing codes, not assume a new CPT code will be created.
3.4 Additional Risk / Documentation Concepts
Medical Necessity▶
Risk Coding / Documentation Optimization▶
Attribution▶
Eligibility & Coverage Rules▶

3. It reduces clinical or operational burden
4. It meaningfully affects quality metrics or financial outcomes
05
Regulation & Compliance
HIPAA▶
State Privacy Laws (CCPA, CPRA, etc.)▶
BAA (Business Associate Agreement)▶
SOC 2 Type II▶
• Type I = “we have policies.”
• Type II = “we follow them consistently.”
HITRUST▶
FDA Medical Device Classification▶
● Class I: Low risk, general controls
● Class II: Moderate risk; requires 510(k) or special controls
● Class III: High risk; requires Premarket Approval (PMA) with clinical trials
510(k) Pathway▶
De Novo Pathway▶
PMA (Premarket Approval)▶
SaMD (Software as a Medical Device)▶
Non-Device CDS Exemption▶
PCCP▶
ONC Certification (CEHRT)▶
21st Century Cures Act (Info Blocking)▶
CDR / Auditability Requirements▶
Telehealth Licensure Requirements▶
HITECH Act▶
OIG & Anti-Kickback Statute (AKS)▶
06
Interoperability & Data
FHIR▶
USCDI▶
SMART on FHIR▶
● embedded workflows inside the clinician’s EHR
● single sign-on
● reduced friction during clinical use
Embedding into the EHR is one of the strongest adoption drivers. But only a subset of EHRs fully support SMART.
HL7 v2▶
C-CDA▶
ADT Feeds▶
QHIN (Qualified Health Information Network)▶
TEFCA▶
Information Blocking Rule▶
De-Identified Data (HIPAA Safe Harbor)▶
Limited Data Set (LDS)▶
Data Use Agreement (DUA)▶
Encryption & Security Requirements▶
Patient Access APIs▶
Common Founder Mistakes in Interoperability▶
• Assuming EHR vendors want to integrate. They often don’t; business models may conflict.
• Underestimating testing + certification steps. Even small integrations undergo weeks of validation.
• Ignoring HL7 v2. It’s still mandatory in many workflows.
• Not budgeting for interface fees. Some EHRs charge per interface, per site, per data type.
• Forgetting operational integration. Technical integration is only half; workflow integration is often harder.
07
Clinical Evidence & Validation
Real-World Data (RWD)▶
Real-World Evidence (RWE)▶
Pragmatic Trials▶
Comparative Effectiveness Research▶
Coverage with Evidence Development (CED)▶
Phases 1-4 Clinical Trials▶
● Phase 2: Preliminary efficacy
● Phase 3: Confirmatory trials for approval
● Phase 4: Post-marketing evidence
ROI vs VOI▶
● VOI: Soft value (e.g., patient satisfaction, clinical champion engagement, staff workload reduction).
● CFOs only sign for ROI → determines whether a pilot turns into a contract.
Founders must articulate both – VOI to get inside the door, ROI to get paid.
The J-Curve of Validation▶
Pilot Design▶
● Clear success criteria
● Pre-defined conversion triggers
● Assigned champion
● Data access commitments
● End-of-pilot decision deadline
Pilotitis▶
● Require defined success metrics
● Require pre-agreed conversion criteria
● Require data access to measure ROI
● Limit pilots to short, time-bound windows
● Only pilot with organizations who have a budget owner committed
Without these terms, pilots rarely convert.
Evidence Requirements by Stakeholder▶
• Payers: Want cost reduction, clinical outcomes, and quality improvements tied to measures.
• Employers: Want utilization improvement (ED/urgent care avoidance), absenteeism reduction, and patient experience.
• Pharma: Wants adherence, real-world outcomes, or disease insights.
Founders often fail because they collect the wrong type of evidence for the buyer they are selling to.
Attribution (Who Gets Credit)▶
Regression to the Mean▶
Clinical KPIs vs Financial KPIs▶
● Financial KPIs: ED visits, readmissions, hospitalizations, medication adherence, risk adjustment accuracy
Digital Health Evidence Maturity Curve▶
● Stage 1: Engagement
● Stage 2: Behavioral change
● Stage 3: Clinical outcome
● Stage 4: Cost reduction
08
Pharma, PBMs & Drug Channels
PBMs (Pharmacy Benefit Managers)▶
Intermediaries managing the pharmacy benefit for health plans and employers. PBMs control formularies, negotiate drug prices, extract rebates from manufacturers, determine member cost-sharing, and manage pharmacy networks and utilization rules.
Formularies & Tiers▶
Rebates (Manufacturer → PBM)▶
Specialty Pharmacy▶
White Bagging▶
Brown Bagging▶
Clear Bagging▶
Medical vs. Pharmacy Benefit▶
● Medical benefit: Covers drugs administered by clinicians (infusions, injections)
● Medical benefit drugs require provider billing (J-codes, buy-and-bill)
● Pharmacy benefit drugs require PBM alignment
Digital health tools must understand which benefit applies to the medications they influence.
Utilization Management (UM)▶
Specialty Drug Prior Authorization▶
Pharma Commercial Teams▶
● Adherence support
● Patient identification
● Real-world evidence generation
● Patient onboarding/coaching
Understanding how pharma evaluates partnerships unlocks new revenue channels.
Hub Services▶
Copay & Affordability Programs▶
Patient Support Programs (PSPs)▶
Where Digital Health Fits Into the Drug Channel▶
● Adherence (behavioral, reminders, coaching)
● Prior authorization automation
● Patient onboarding for complex therapies
● Remote monitoring of safety/efficacy
● Real-world evidence generation
09
Business Models & Contracting
SaaS (Software as a Service)▶
PMPM (Per Member Per Month Pricing)▶
Shared Savings▶
● Clear baselines
● Data sharing
● Attribution logic
● Agreement on measurement methods
Founders often underestimate how hard it is to validate savings rigorously.
Direct-to-Consumer (D2C)▶
Hybrid Clinical + SaaS Model▶
Results-Based or Performance-Based Contracts▶
10
The Most Critical Entries for Startups
Pilotitis▶
● But without strict success criteria, they rarely turn into paid deals
● Pilots consume engineering resources, product time, and credibility
To avoid Pilotitis, founders must insist on:
● Pre-agreed success metrics
● Conversion triggers (what turns pilot → contract)
● Clear budget owner
● Defined timeline and decision date
If a buyer will not define success criteria or budget path, the pilot is a dead end.
Sales Cycle▶
● Providers: 12–18 months (longer for IDNs)
● Health plans: 18–24 months
● Employers: 3–9 months
Underestimating sales cycle length is a leading cause of startup failure. Your fundraising must accommodate at least one full cycle.
Procurement (IT + Security Review)▶
Budget Owner vs. Influencer vs. User▶
● User = clinician, care manager, patient
● Influencer = medical directors, quality leaders
● Buyer = CFO, benefits director, service line administrator
Buyer / User / Beneficiary Triangle▶
● Buyer: employer
● User: employee
● Beneficiary: the health plan (cost savings)
MSA, BAA, SLA (Contract Bundle)▶
● BAA: Defines PHI handling responsibilities
● SLA: Defines uptime, performance, support standards
Benefits Consultants (as a Contracting Layer)▶
GPO Contracts (Hospitals)▶
Utilization Management Integration▶
Risk Contracting Alignment▶
Pricing Strategy Mistakes (Common Founder Pitfalls)▶
• A PMPM price that exceeds the actuarial value delivered
• Assuming clinicians will pay out-of-pocket for software
• Charging providers for solutions that reduce FFS revenue
• Forgetting to include integration costs
• Underestimating procurement friction
Healthcare pricing must map to economic impact, not product cost.
J-Curve of Commercial Traction▶
Contracting “Triggers” (What Buyers Need Before Signing)▶
• Champion buy-in
• Security approval
• Integration feasibility
• Clear budget line
• Demonstrated patient adoption
Missing even one can kill deals.
