Compliance Criteria for E-Prescribing

HIPAA Compliance

You need verifiable controls for the HIPAA Privacy, Security, and Breach Notification Rules. Confirm risk analysis, risk management, workforce training, and administrative, physical, and technical safeguards. Ensure minimum necessary access, encryption, and documented incident handling.

DEA Controlled Substance Regulations (EPCS)

For controlled substances, require identity proofing by a trusted provider, multi-factor authentication, logical access controls, and independent third-party assessment of the EPCS application. Validate tamper-resistant prescription creation, approver separation, and revocation processes for prescriber credentials.

NCPDP SCRIPT Standard Conformance

The platform must implement the NCPDP SCRIPT Standard for e-prescribing transactions. Confirm support for NewRx, CancelRx, RxChange, RxHistory, renewals, and acknowledgments, with accurate code sets and error handling. Require plans for timely adoption of future SCRIPT releases.

Audit Trail Requirements

Ensure immutable, time-synchronized logs that record user identity, patient, prescription details, transaction type, status, and all administrative actions. Logs should be protected from alteration, retained per federal and state rules, and retrievable for legal hold and investigations.

Privacy and Patient Safety

Verify alignment with 42 CFR Part 2 where applicable, state PDMP integration workflows, and drug-drug/allergy checks. Require safe defaults that prevent incomplete or ambiguous prescriptions and support CancelRx to reduce medication errors.

Security Requirements

Data Encryption Protocols

• Encrypt data in transit with modern TLS (with forward secrecy), strong cipher suites, and certificate pinning where feasible.
• Encrypt data at rest with AES-256 or equivalent using FIPS-validated modules; manage keys in an HSM with rotation, separation of duties, and dual control.
• Protect backups with encryption, access controls, immutability, and routine restore testing.

Identity, Access, and Authentication

• Use prescriber identity proofing aligned to rigorous standards and enforce MFA for EPCS approval actions.
• Implement RBAC/ABAC, just-in-time access, and periodic recertification; monitor and alert on anomalous behavior.
• Support SSO via OpenID Connect/OAuth 2.0 or SAML, with conditional access and device hygiene checks where possible.

Application and Network Security

• Adopt secure SDLC with threat modeling, SAST/DAST, composition analysis, and manual code reviews for high-risk components.
• Segment networks, restrict management planes, and harden endpoints with EDR; manage vulnerabilities with defined SLAs.
• Run regular penetration tests and red-team exercises; provide executive summaries and remediation evidence.

Electronic Prescription Security

• Use digital signatures or message authentication to preserve prescription integrity and non-repudiation.
• Enforce tamper-evident records, duplicate detection, and strict CancelRx/change workflows to avoid diversion.
• Implement resilient queuing, retries with backoff, and positive/negative acknowledgments to prevent loss or duplication.

Operations, Monitoring, and Resilience

• Centralize logs in a SIEM with correlation rules for EPCS events and high-risk actions; support on-demand exports for investigations.
• Maintain tested incident response runbooks, defined communication plans, and forensic readiness.
• Design for business continuity with multi-region deployments, automated failover, and documented RTO/RPO targets.

Risk Assessment Procedures

Scope and Inherent Risk

• Classify the vendor by data sensitivity (PHI, PII), transaction volume, integration depth, and criticality to clinical operations.
• Map data flows end-to-end, identifying subprocessors, storage locations, and cross-border transfers.

Evidence Collection and Validation

• Use standardized questionnaires to gather controls evidence, then validate against independent attestations and sample configurations.
• Perform technical spot checks: TLS configuration scans, API auth flows, and log integrity tests.
• Interview security leadership and review change management boards, risk registers, and recent incident postmortems.

Risk Scoring and Treatment

• Score risks by likelihood and impact; map to your control framework and document compensating controls.
• Create remediation plans with owners and deadlines; tie go-live to completion of high-priority actions.
• Decide on risk acceptance, mitigation, transfer, or avoidance with clear executive sign-off.

Ongoing Vendor Risk Management

• Monitor performance SLAs, security metrics, penetration test cadence, and patch timelines.
• Track change notices, new subprocessors, and reportable incidents; refresh due diligence on a defined cycle.
• Test exit procedures annually to ensure data portability and minimize lock-in risk.
