A HealthTech Engineer’s Regret: 5 Costly HIPAA Compliance Mistakes I Made (And How to Avoid Them)

Building software for healthcare? You’re not just coding—you’re handling real people’s private data. HIPAA isn’t just paperwork to check off. It’s the backbone of trust in HealthTech. And after years in the trenches, I’ve learned the hard way that cutting corners here comes with painful consequences.

My Early Days in HealthTech: A Compliance Wake-Up Call

When I started in HealthTech, I was all energy and no caution. I wanted to build tools that helped people, fast. EHR integrations, telemedicine, dashboards—I was proud of what we made. But I focused on speed, not safeguards.

Then came our first audit. We’d built a telemedicine platform that clinics loved. We used HTTPS, encrypted data, and React. We thought we were solid. Then the compliance officer asked, “Where are your audit logs? Who can access them?”

I had no answer. We hadn’t set up audit trail retention or tracked access control logging. The result? Six months of rework, a $40K fine, and a lost client. That moment taught me: in HealthTech, compliance isn’t optional. It’s part of your product.

The 5 HIPAA Compliance Mistakes I Regret the Most

These five mistakes cost me time, money, and peace of mind. If you’re building in healthcare, learn from my regrets—not your own.

1. Treating Encryption as an Afterthought

At first, I saw encryption like a light switch: on or off. “Encrypted at rest?” Check. “In transit?” Check. Done. But that’s not how HIPAA works.

Under 45 CFR § 164.312(a)(2)(iv), ePHI needs strong encryption standards. We used AES-128 and TLS 1.2—but we skipped end-to-end encryption (E2EE) for video calls. And our encryption keys? Just sitting in environment variables. A hacker’s dream.

How to fix it: Use a key management service (KMS) like AWS KMS or Google Cloud KMS. Apply envelope encryption for EHR data. And never, ever store keys with data.


// Example: Envelope Encryption with AWS KMS
const crypto = require('crypto');
const { KMSClient, GenerateDataKeyCommand } = require('@aws-sdk/client-kms');

async function encryptEHRData(data) {
const kms = new KMSClient({ region: 'us-east-1' });
const command = new GenerateDataKeyCommand({
KeyId: 'alias/healthtech-ehr-key',
KeySpec: 'AES_256'
});
const { Plaintext, CiphertextBlob } = await kms.send(command);

const iv = crypto.randomBytes(16);
const cipher = crypto.createCipheriv('aes-256-cbc', Plaintext, iv);
let encrypted = cipher.update(JSON.stringify(data), 'utf8', 'base64');
encrypted += cipher.final('base64');

return { encryptedData: encrypted, iv: iv.toString('base64'), key: CiphertextBlob.toString('base64') };
}


This way, even if your database leaks, the keys aren’t there. Your ePHI stays safe.

2. Ignoring Audit Trails Until It Was Too Late

We didn’t log who accessed patient records—until someone did. We couldn’t tell if it was an insider or a hacker. No logs, no proof. Just panic.

HIPAA requires audit controls (45 CFR § 164.308(a)(1)(ii)(D)) and logs kept for at least six years. No exceptions.

How to fix it: Log every access. Who, what, when, where. Use structured logs with user ID, IP, timestamp, and action. Store them in a secure, immutable system.


// Example: Audit log middleware for Express.js
app.use((req, res, next) => {
const userId = req.user?.id || 'anonymous';
const action = req.method + ' ' + req.path;
const ip = req.ip;
const timestamp = new Date().toISOString();

logger.info('ACCESS_LOG', {
userId,
action,
ip,
timestamp,
userAgent: req.get('User-Agent')
});

res.on('finish', () => {
logger.info('RESPONSE_LOG', {
userId,
statusCode: res.statusCode,
responseTime: Date.now() - req.startTime
});
});

next();
});


Use AWS S3 with Object Lock or a similar WORM solution. Once logs are written, they can’t be altered. That’s what auditors want to see.

3. Assuming “HIPAA-Compliant Cloud” Means Full Compliance

We used AWS—“HIPAA-eligible,” they said. We assumed that meant we were covered. It didn’t.

Cloud providers offer tools. But you’re still responsible for how you use them. Open S3 buckets, weak IAM policies, missing MFA—those are all on you.

How to fix it: Don’t trust defaults. Run a cloud security posture assessment. Tools like AWS GuardDuty or Prowler can catch misconfigurations fast.

• Block all public S3 access by default
• Require MFA for root and all users
• Enable VPC flow logs
• Rotate access keys regularly

4. Poor Access Control in Telemedicine Platforms

Our app let nurses join video visits. But once in, they could see full patient records—including sensitive mental health notes. Just because they worked in the same clinic.

HIPAA’s Minimum Necessary Standard (45 CFR § 164.502(b)) says: only give access to what’s needed. Nothing more.

How to fix it: Use role-based access control (RBAC) and attribute-based access control (ABAC) in your APIs and databases.


// Example: ABAC policy for EHR access
function canViewEHR(user, patient) {
if (user.role === 'doctor' && user.specialty === patient.specialty && user.clinicId === patient.clinicId) {
return true;
}
if (user.role === 'nurse' && user.clinicId === patient.clinicId && user.ward === patient.ward) {
return true;
}
return false;
}


For sensitive data—like psychotherapy notes—add two-person authentication. One person alone shouldn’t have full access.

5. No Business Associate Agreement (BAA) with Third Parties

We added a third-party analytics tool to track app usage. Turns out, it processed ePHI. We didn’t know. When they got breached, we were on the hook—because we had no BAA.

Under HIPAA, any vendor that touches ePHI is a Business Associate. And you must have a signed BAA. No excuses.

How to fix it: Before you integrate anything, ask:

• Will they sign a BAA?
• Do they audit their security yearly?
• Do they encrypt and log like you do?
• How do they notify you if something goes wrong?

Use tools like Compliance Manager or OneTrust to track BAAs and renewal dates.

How to Build a Sustainable HIPAA Compliance Culture

Compliance isn’t a one-time task. It’s how your team thinks, builds, and responds. Here’s how I changed my team’s mindset.

1. Shift-Left Security

Don’t wait for audits. Bake compliance into your workflow. Use tools to catch issues early:

• Bandit for Python security
• Gitleaks to find secrets in code
• Checkov to scan infrastructure as code

If a scan finds a problem, stop the deployment. Fix it first.

2. Annual Risk Assessments

Do a HIPAA Security Risk Analysis (SRA) every year. Use the NIST 800-30 framework. It walks you through threats, gaps, and fixes.

3. Developer Training

Train your team—quarterly. Real stories, real code, real risks.

• Break down recent health data breaches

<

• Review code with security in mind
• Run phishing drills to test awareness

The best engineers aren’t just fast—they’re careful.

Conclusion: Keep Your “Coins” — Build Compliant, Not Just Functional

Every mistake I made felt small at the time. A shortcut here, a delay there. But those choices cost us big. Like selling a rare coin for a short-term gain—I traded long-term safety for speed.

In HealthTech, your code protects lives. It’s not just about features. It’s about trust, privacy, and safety. Every decision—encryption, access, logging—matters.

Don’t wait for an audit. Or a breach. Start today. Build with HIPAA in mind from the first line of code. That’s how you protect your patients—and your career.

Be the engineer who keeps their coins. Not the one who regrets letting them go.
