Fraud-Resistant Patient Enrollment Records

A shared, permissioned ledger creates a single source of truth for patient identity, preventing the same individual from enrolling multiple times under different identities—a common source of fraud in Medicaid and clinical trials. Real-world impact: A major U.S. health insurer reduced duplicate member records by 15% in a pilot, directly cutting overpayment losses and administrative reconciliation costs.

Every enrollment event—from initial sign-up to eligibility changes—is time-stamped and cryptographically sealed on-chain. This creates an immutable audit trail that satisfies HIPAA, GDPR, and payer requirements. ROI Driver: Slash audit preparation time by up to 70% and eliminate fines for incomplete documentation. For example, a European health network reduced its annual audit compliance costs by €2M after implementation.

Break down data silos between hospitals, insurers, and clinics. With patient consent managed via smart contracts, verified enrollment data can be shared instantly and securely, without manual faxes or portals. Key Benefits:

• Accelerate prior authorizations from days to minutes.
• Enable real-time eligibility checks at point of care.
• Reduce administrative FTEs dedicated to manual data requests.

Give patients control over their enrollment data via a private key or wallet. They can selectively share verified credentials with new providers, eliminating repetitive form-filling. This builds loyalty and reduces attrition. Business Case: A direct-to-employer health plan using this model saw a 25% increase in patient satisfaction scores and a 12% reduction in customer service calls related to enrollment issues.

Automate manual, error-prone processes like data entry, verification, and reconciliation between systems. Smart contracts can trigger workflows (e.g., sending welcome kits, updating CRM) upon successful on-chain enrollment. Cost Savings: A regional hospital network reported reducing its cost per enrollment by 40% and cutting data entry errors by 95%, reclaiming hundreds of staff hours monthly.

Immutable enrollment records are the foundation for accurate attribution in value-based contracts. They definitively link patients to providers and payers, ensuring correct reimbursement for outcomes. Strategic Advantage: Enables participation in advanced payment models that require verifiable, tamper-proof patient rosters, opening new revenue streams and improving margin predictability.

The Pain Point: Coordinating benefits and enrollment across primary and secondary payers (e.g., Medicare and a supplemental plan) involves slow, manual processes prone to errors and disputes.

The Blockchain Fix: A shared ledger among payers allows for real-time synchronization of a patient's enrollment status, coverage details, and coordination of benefits rules via smart contracts.

• Real Example: While full multi-payer systems are emerging, consortium models like the Synaptic Health Alliance explore using blockchain to maintain accurate provider directories, a foundational step for enrollment data.
• Business ROI: Accelerates claims processing, reduces inter-payer disputes, and improves patient satisfaction by simplifying their billing experience.

The Pain Point: The manual patient onboarding process is a major cost center, involving data entry, verification calls, and document processing.

The Blockchain Fix: Zero-knowledge proofs (ZKPs) allow patients to prove they meet enrollment criteria (e.g., residency, income) without revealing the underlying sensitive documents. This automates verification.

• Real Example: Protocols like zkPass are pioneering the use of ZKPs for private data verification, enabling applications where users can prove eligibility from verified sources.
• Business ROI: Can reduce the cost of patient onboarding by over 50% by automating manual checks, while simultaneously enhancing privacy and security.
