Vendor Due Diligence Checklist for an AI Prior Authorization Company Before Granting Limited EHR Scopes

Security Controls Evaluation

Before you grant any limited EHR scopes, confirm the vendor’s baseline security posture. Look for mature controls that protect ePHI end to end, demonstrate operational discipline, and align with healthcare risk tolerance.

Core technical protections

• Data encryption protocols: TLS 1.2+ (preferably 1.3) in transit; AES‑256 at rest; FIPS‑validated crypto modules; documented key management, rotation, and HSM/KMS usage.
• Identity security: SSO via SAML/OIDC, enforced MFA, least‑privilege role design, privileged access management (PAM), and just‑in‑time elevation with approvals.
• Network and endpoint defenses: segmented VPCs/VLANs, egress controls, WAF and DDoS protections, hardened images, EDR/AV on servers and workstations, and mobile device management for workforce devices.
• Logging and monitoring: centralized, tamper‑resistant audit logs for all EHR reads/writes; SIEM with alerting; time‑synced systems; retention aligned to regulatory needs.
• Backup and recovery: encrypted, immutable backups; tested restores; documented RTO/RPO targets tied to prior authorization service continuity.

Secure development and operations

• SDLC controls: threat modeling, peer code review, SAST/DAST, dependency scanning with SBOM, and vulnerability SLAs (e.g., critical within days, highs within weeks).
• Change management: documented change windows, rollback plans, and risk sign‑offs for model or API revisions impacting EHR data flows.
• Assurance: independent penetration tests at least annually and after major changes, plus remediation tracking through closure.

Compliance with Healthcare Regulations

Require clear, auditable evidence of HIPAA compliance and alignment with HITECH Act requirements. The vendor should show how its controls map to Privacy, Security, and Breach Notification Rules.

• HIPAA compliance artifacts: enterprise risk analysis and risk management plan; policies and procedures; workforce training records; sanctions and disciplinary process; audit controls and access reviews.
• HITECH Act requirements: breach notification workflows; encryption at rest/in transit to reduce exposure; accounting of disclosures when EHR data is accessed or shared.
• Business Associate Agreement (BAA): scope of services, permitted uses/disclosures, minimum necessary enforcement, and subcontractor (downstream) obligations.
• Minimum necessary standard: documented data minimization logic for prior authorization decisions; proof that only essential EHR elements are retrieved.
• Regulatory horizon scanning: process for tracking state privacy laws and 42 CFR Part 2 where applicable; legal review cadence for new jurisdictions.

Data Privacy and Consent Management

Protecting patient trust requires rigorous privacy governance, transparent data practices, and consent management that respects purpose limitations for limited EHR scope access.

Consent capture and enforcement

• Consent provenance: who authorized access, when, for what purpose, and how it is tied to each API call or record set.
• Revocation and expiry: real‑time enforcement when consent changes; time‑boxed tokens; automatic scope expiration and renewal prompts.
• Limited access scope governance: granular, patient‑ or encounter‑level filters; redaction of non‑essential elements; auditable scope decisions.

Privacy by design

• Data minimization: field‑level extraction aligned to medical‑necessity criteria; avoidance of full‑record pulls; suppression of free‑text where feasible.
• De‑identification and pseudonymization: HIPAA‑aligned techniques for analytics or model training; separation of identifiers; secure re‑linking only when justified.
• Retention and deletion: documented schedules; secure disposal; customer‑controlled retention overrides for legal holds.

AI algorithm transparency and ethics

• AI algorithm transparency: explanations suitable for clinicians and auditors; versioning of models and decision rules; change logs for model updates.
• Bias and performance monitoring: drift detection, fairness checks across populations, and human‑in‑the‑loop validations for edge cases.
• Training data governance: no training on customer PHI without explicit, contractually defined consent; strong isolation of environments.

System Integration Capabilities

Assess whether the solution integrates cleanly and securely using widely adopted EHR interoperability standards while preserving limited scope boundaries.

• Standards support: HL7 FHIR R4 (e.g., CoverageEligibilityRequest/Response, Patient, Coverage, Claim), SMART on FHIR launch, OAuth 2.0/OIDC, and—where required—HL7 v2 or X12 transactions (e.g., 278) with attachments.
• Prior authorization frameworks: alignment with HL7 Da Vinci use cases (CRD, DTR, PAS) to streamline documentation and payer submissions.
• Security in integration: fine‑grained FHIR scopes (patient/*.read), confidential clients, PKCE where applicable, signed JWTs, and short‑lived tokens.
• Reliability and scale: documented SLOs, rate limits, idempotency keys, replay protection, webhook signatures, and backoff strategies.
• Data fidelity: mapping for ICD‑10‑CM, CPT/HCPCS, LOINC, and SNOMED CT; robust error handling and reconciliation reports.
• Lifecycle readiness: sandbox environments, versioned APIs, migration plans, and rollout playbooks for phased go‑lives.

Risk Management and Incident Response

Your vendor should operate a living risk program and a tested incident response plan that rapidly contains issues and meets notification obligations.

• Enterprise risk register: documented risks with owners, likelihood/impact, and treatment plans; periodic reviews with leadership.
• Third‑party risk assessment: due diligence for all subcontractors handling ePHI; flow‑down BAAs; continuous monitoring of critical suppliers and cloud platforms.
• Detection and response: 24×7 monitoring, severity classification, containment and eradication runbooks, forensics readiness, and executive/on‑call rotations.
• Breach notification: processes to notify covered entities without unreasonable delay and within HIPAA timeframes; state‑law considerations and evidence preservation.
• Resilience: business continuity and disaster recovery testing, documented RTO/RPO, and failover drills for prior authorization workloads.
• Post‑incident improvement: root‑cause analysis, corrective actions, and regression testing to prevent recurrence.

Vendor Financial and Operational Stability

Stability reduces service risk during critical authorization windows. Validate financial strength and operational maturity before connecting to EHR data.

• Financial health: audited or management financials, cash runway, burn rate, revenue concentration analysis, and insurance coverage (e.g., E&O/cyber).
• Corporate hygiene: governance structure, board oversight, compliance attestations, and clean litigation/background checks.
• Operational maturity: staffing levels and skills, background screening, training programs, low turnover in security/engineering, and 24×7 support capabilities.
• Service reliability: documented SLAs/SLOs, escalation paths, maintenance windows, and customer success metrics tailored to prior authorization throughput and decision times.
• Roadmap alignment: product plans that track regulatory changes and payer/EHR updates; deprecation policies and long‑term support commitments.

Access Controls and Authorization Policies

Limited EHR scope access must be enforced by design. Verify policy depth, automation quality, and auditability across the access lifecycle.

• Limited access scope governance: ABAC/RBAC with context (patient, encounter, org, purpose), short token lifetimes, and per‑request policy evaluation with full audit trails.
• Granular permissions: FHIR resource‑level scopes, environment and tenant isolation, and explicit prohibitions on write access unless contractually required.
• User lifecycle: SCIM provisioning/de‑provisioning, periodic access recertifications, separation of duties for admins, and JIT approvals for elevated tasks.
• Session and secret hygiene: strong session management, key rotation, vaulted secrets, IP allow‑listing for admin interfaces, and device posture checks.
• Transparency and accountability: end‑user access reports, patient access logs upon request, and immutable evidence to support audits.

Conclusion

Grant limited EHR scopes only after you confirm strong security controls, demonstrable HIPAA compliance, disciplined privacy and consent practices, standards‑based integration, active risk management, solid financial/operational footing, and enforceable authorization policies. This due diligence reduces risk while enabling faster, safer AI‑driven prior authorizations.
