Code Audit for Healthcare
Your healthcare platform handles patient data. We make sure your code handles it correctly - tracing every PHI flow, encryption boundary, and access control decision.
Variant Systems brings deep domain experience so you ship compliant, production-ready software from day one.
Why this combination
- Healthcare code audits must evaluate compliance, not just code quality
- We trace PHI data flows across every layer of your application
- Findings are mapped to HIPAA requirements so your compliance team can act immediately
- We've audited health tech platforms from seed stage to enterprise
Patient Data Safety Over Code Quality Metrics
A code audit for a healthcare platform can’t just look at code quality metrics and call it done. The real question isn’t whether your code is clean. It’s whether patient data is safe.
Healthcare software operates under HIPAA’s technical safeguard requirements. That means encryption, access controls, audit logging, and transmission security aren’t nice-to-haves. They’re legal obligations. A standard code review won’t catch a PHI field that’s logged in plaintext, or an API endpoint that returns patient records without proper authorization checks, or an EHR integration that transmits HL7 messages over an unencrypted channel.
We audit healthcare code with a compliance-first lens. Every finding gets mapped to the HIPAA Security Rule requirement it relates to. Your compliance officer and your engineering lead both get something they can act on.
The stakes are real. A single HIPAA violation can result in penalties from $100 to $50,000 per occurrence, with annual maximums reaching $1.5 million per violation category. Beyond fines, a breach notification requirement can damage patient trust and derail partnerships with health systems. A thorough code audit is cheaper than any of those outcomes.
PHI Flows, Encryption, Access Controls, and EHR Security
We start with PHI data flows. Where does patient data enter your system? How does it move between services? Where is it stored, cached, or logged? Where does it leave your system - to EHR platforms, analytics services, email providers, error tracking tools? Every PHI touchpoint gets documented and evaluated.
Encryption is next. We verify that data at rest uses AES-256 or equivalent, that TLS 1.2+ is enforced for all transmissions, and that key management follows established practices. We check database-level encryption, application-level encryption for sensitive fields, and backup encryption. We also look for the gaps people miss - PHI in search indexes, cached API responses, temporary files, and log aggregators.
Access controls get a thorough review. We evaluate your RBAC implementation, session management, API authentication, and inter-service authorization. We check whether the principle of least privilege is actually enforced or just documented. We look at how access is granted, revoked, and audited.
Audit logging is critical for HIPAA compliance. We verify that your system records who accessed what PHI, when, and from where. We check log integrity, retention policies, and whether logs themselves are protected from tampering.
For EHR integrations, we assess FHIR and HL7 implementations for data validation, error handling, and security. We check whether inbound data is sanitized and whether outbound data includes only the minimum necessary PHI.
From Architecture Discovery to HIPAA Mapping
We begin with architecture discovery. We review your infrastructure configuration, application architecture, and deployment pipeline. We need to understand the full picture before we can identify where PHI might be exposed.
Then we do a systematic code review, tracing PHI data paths through your codebase. We’re not skimming - we follow every data flow from ingestion to storage to retrieval to deletion. We use static analysis tools where they’re useful, but the core work is manual review by engineers who understand both healthcare compliance and software architecture.
We test authentication and authorization boundaries. Can a user in one practice access another practice’s patient records? Can a patient see another patient’s data through IDOR vulnerabilities? Does your API enforce the same access rules as your UI? We verify these boundaries systematically.
We also review your BAA coverage. If you’re using third-party services that handle PHI - cloud providers, email services, analytics platforms, error tracking - we verify that appropriate agreements are in place and that the integrations are configured correctly.
Every finding is categorized by severity and mapped to the relevant HIPAA requirement. Critical findings - PHI exposure, broken encryption, missing access controls - are flagged immediately so you can begin remediation before the full report is delivered.
Stakeholder Reports and Remediation Roadmap
You receive a detailed report with three sections tailored to different stakeholders. The executive summary gives leadership a clear picture of compliance posture and risk exposure. The technical findings give your engineering team specific code locations, reproduction steps, and remediation guidance. The compliance mapping gives your compliance officer a HIPAA crosswalk showing which safeguards are met, partially met, or missing.
We include a prioritized remediation roadmap. Not everything needs to be fixed at once, but some things need to be fixed this week. We help you distinguish between the two and sequence the work so the highest-risk gaps close first.
We’re available for a follow-up session with your engineering team to walk through findings, answer questions, and discuss implementation approaches. If you want us to handle the remediation, we can do that too. But the audit stands on its own - you’ll have everything you need to fix things with your own team if that’s the path you choose.
For investors evaluating healthtech acquisitions, our audit quantifies HIPAA remediation cost and compliance timeline - the numbers your investment committee needs. We deliver a deal-oriented executive summary that translates technical findings into integration risk and regulatory exposure, so your diligence team can factor compliance gaps directly into the transaction model.
