HIPAA Compliance Requirements for Custom Healthcare Software
If you're building custom software that touches patient data, HIPAA isn't optional. It's the baseline. And yet, we see healthcare companies make the same compliance mistakes over and over, usually because their development team treated HIPAA as an afterthought rather than a design constraint.
We've built multiple healthcare platforms, from medical records management systems to concierge care coordination tools to payment portals handling insurance claims. Every one of them required HIPAA compliance baked into the architecture from day one. Not bolted on at the end. Not handled by a checkbox on a vendor questionnaire.
Here's what healthcare companies actually need to get right when building custom software that handles protected health information (PHI).
What HIPAA Actually Requires of Your Software
HIPAA gets talked about in vague terms a lot. "Be HIPAA compliant" is about as useful as "be secure." The reality is more specific. The Security Rule lays out three categories of safeguards your software needs to address: administrative, physical, and technical.
For custom software development, the technical safeguards are where most of the engineering work happens. But the administrative ones trip people up more often because they're about processes, not code.
Encryption: At Rest and In Transit
This one sounds simple, and it mostly is. All PHI must be encrypted when it's stored (at rest) and when it's moving between systems (in transit).
In transit means TLS 1.2 or higher for all connections. No exceptions. Every API call, every database connection, every file transfer that carries patient data needs encryption.
At rest means your database, your file storage, your backups, and your logs (if they contain PHI) all need encryption. AES-256 is the standard most auditors expect to see.
Where teams stumble: temporary files, cache layers, search indexes, and log files. It's easy to encrypt the main database and forget that your application writes PHI to a temp directory during PDF generation, or that your search engine has unencrypted copies of patient records in its index.
On one healthcare platform we built, we identified 14 distinct locations where PHI could exist in the system, from the primary database to cached API responses to generated reports queued for download. Each one needed its own encryption strategy.
Access Controls: The Principle of Least Privilege
Every user should have access to exactly the data they need to do their job. Nothing more.
This sounds obvious, but implementing it properly in a multi-role healthcare application is harder than most teams expect. A medical records management system we built had four distinct user roles: administrators, attorneys, providers, and custodians. Each role needed different views of the same underlying data, with different permissions for reading, creating, modifying, and exporting records.
Role-based access control (RBAC) is the minimum. For healthcare applications with complex organizational hierarchies, you often need attribute-based access control (ABAC) too, where access depends not just on the user's role but on their relationship to the specific patient, facility, or case.
A care coordination platform we developed had seven user roles, including coordinators, case managers, approvers, billing staff, and CFO-level oversight. Each role could see different subsets of patient case data, and access was further scoped by which employer plans they were authorized to manage.
Common mistakes we see:
- Giving all staff members admin-level database access during development, then never locking it down
- Building role checks only in the UI while the API returns unrestricted data
- Forgetting to restrict access to exported files and reports
- Not revoking access when staff roles change or people leave
Audit Logging: Who Accessed What, When
HIPAA requires that you track who accesses PHI and when. This isn't just "keep server logs." It means building application-level audit trails that record every meaningful interaction with patient data.
Good audit logging captures:
- Who accessed the record (user ID, role, IP address)
- What they accessed (which patient, which data fields)
- When they accessed it (timestamp)
- What they did (viewed, edited, exported, deleted)
- Why they accessed it (linked to a case, task, or workflow step)
The "why" is the part most systems miss. Knowing that a user viewed a patient record is useful. Knowing they viewed it because they were assigned to that patient's case, and they were performing a billing review, is what makes an audit trail actually meaningful during an investigation.
In one concierge care platform, we built a full activity audit trail that logged every action across the patient case lifecycle, with 17 distinct case statuses from initial request through billing and resolution. Every status change, every document access, every communication was logged with context.
Where Off-the-Shelf Software Falls Short
Healthcare companies often start with generic tools: a standard CRM, a project management app, maybe some shared spreadsheets for tracking patient information. They assume these tools are "HIPAA compliant" because the vendor says so on their website.
There are two problems with this assumption.
Problem 1: The BAA Gap
A Business Associate Agreement (BAA) is a legal contract required by HIPAA whenever a third party handles PHI on your behalf. Your software vendors, your hosting providers, your email service, your payment processor: if they touch patient data, you need a BAA with them.
Many SaaS tools will sign a BAA. But signing a BAA doesn't mean the tool is configured correctly for HIPAA compliance. It means the vendor agrees to be responsible for their part. Your configuration, your data handling practices, and how your team actually uses the tool are still on you.
We've seen healthcare organizations using mainstream CRM platforms with signed BAAs while simultaneously emailing unencrypted patient spreadsheets to staff members' personal accounts. The BAA covered the CRM. It didn't cover the workflow around it.
Problem 2: Workflows That Don't Fit
Healthcare workflows are specific. A claims processing system needs to handle UB-04 and CMS-1500 form formats. A care coordination platform needs to track patients through intake, scheduling, procedures, billing, and follow-up with specific data requirements at each step. A medical records system needs to manage request lifecycles across multiple parties with different access levels.
Generic software can't handle these workflows without extensive customization. And extensive customization of off-the-shelf tools often creates its own compliance risks, because you're working around the tool's design rather than with it.
Custom software built for your specific healthcare workflow can enforce compliance at every step because the workflow itself is the architecture.
Multi-Tenant PHI: The Hidden Complexity
If your healthcare platform handles data for multiple organizations, clinics, or employer groups, you're dealing with multi-tenant PHI. This adds a layer of complexity that many development teams underestimate.
In a multi-tenant healthcare system, you need to guarantee that:
- Organization A can never see Organization B's patient data, even through indirect queries or reporting
- Shared infrastructure (databases, file storage, search indexes) has tenant isolation at the data layer
- Administrative users for one tenant can't accidentally (or intentionally) access another tenant's data
- Audit logs are tenant-scoped so each organization can review their own access history
We've built this pattern across multiple healthcare platforms. One medical records system supported multiple law firms, each managing their own patient records for legal cases. The data isolation had to be absolute because firms were sometimes on opposing sides of the same case.
Another platform managed care coordination for multiple self-insured employers and third-party administrators. Each employer's patient data had to be completely isolated, even though the same coordinators might work across accounts.
The technical approaches vary (database-per-tenant, row-level security, application-layer filtering), but the principle is the same: tenant isolation has to be enforced at the lowest possible level, not just at the UI.

Secure Payment Processing in Healthcare
Healthcare payments are complicated. You're dealing with insurance claims, patient responsibility, payment plans, and often multiple payers per episode of care. When payment data intersects with PHI, you're subject to both HIPAA and PCI DSS requirements.
We've handled this intersection on multiple projects:
- A medical records platform with integrated payment processing through multiple gateways (Authorize.Net and Braintree), where payment records needed to be associated with patient cases without exposing card data
- A pediatric therapy payment portal using vault-based tokenization for bulk CSV payment processing, where the system needed to process hundreds of payments without ever storing raw card numbers
- A care coordination system with dual estimate workflows (provider cost vs. client billing with configurable markup) where financial data and PHI lived in the same case records
The key principle: tokenize payment data immediately and never store raw card numbers alongside PHI. Use a PCI-compliant payment vault, reference payments by token, and keep your HIPAA audit trail connected to payment events without duplicating sensitive financial data.
Five Mistakes That Get Healthcare Software Projects in Trouble
Based on what we've seen across healthcare builds, here are the mistakes that cause the most pain.
1. Treating Compliance as a Final Step
"We'll add HIPAA compliance before launch" is the most expensive sentence in healthcare software development. Retrofitting encryption, access controls, and audit logging into an existing system takes two to five times longer than building them in from the start.
The architecture decisions you make in week one (how you structure your database, how you handle authentication, how you log events) determine how hard or easy compliance will be in month six.
2. No Formal Risk Assessment
HIPAA requires a documented risk assessment. Not a mental checklist. An actual written analysis of where PHI exists in your system, what threats it faces, and what controls you've put in place.
Many healthcare companies skip this because it feels like bureaucracy. But the risk assessment is what an auditor asks for first. If you don't have one, everything else you've done is harder to defend.
3. Ignoring the Human Layer
The best-encrypted database in the world doesn't help if a staff member emails a patient list to their personal Gmail. Technical controls need to be paired with training, policies, and workflow design that makes the compliant path the easiest path.
4. Forgetting About Data Export and Portability
HIPAA gives patients the right to access their data. Your system needs to support data export in usable formats. This isn't a feature you can add later without significant rework if your data model wasn't designed for it.
On every healthcare platform we build, data export capabilities are part of the initial architecture. We design data models that support patient-scoped extraction from day one.
5. Assuming Your Cloud Provider Has It Covered
AWS, Azure, and Google Cloud all offer HIPAA-eligible services and will sign BAAs. But "HIPAA-eligible" means they've done their part. Configuration is yours. An S3 bucket with PHI that's publicly accessible violates HIPAA regardless of what your BAA with Amazon says.
You need to configure infrastructure correctly: encrypted storage, private networking, restricted access, proper key management. The cloud provider gives you the tools. Using them correctly is your responsibility.
How We Approach HIPAA-Compliant Healthcare Builds
Our approach starts before any code gets written. Discovery before code isn't just our philosophy for business requirements. It applies to compliance architecture too.
Compliance Architecture During Discovery
During our discovery process, we map out every point where PHI will exist in the system. Every database table, every API endpoint, every file upload, every report, every integration. This map becomes the foundation for your compliance strategy.
We also identify your specific regulatory context. Are you a covered entity or a business associate? Do you need to handle state-level privacy laws in addition to HIPAA? Are there industry-specific requirements (like claims processing formats) that add complexity?
Security by Design
Encryption, access controls, and audit logging go into the first sprint, not the last. The data model includes tenant isolation, field-level access permissions, and audit columns from the initial schema design.
This approach costs slightly more upfront but saves significantly on rework, remediation, and the stress of trying to patch compliance into a system that wasn't designed for it.
Testing and QA for Compliance
Our quality assurance process for healthcare projects includes specific compliance test cases: verifying that role permissions work correctly across all endpoints, confirming that audit logs capture every required event, testing tenant isolation boundaries, and validating encryption at every PHI storage point.
Transparency and ownership are central to how we work. You get full visibility into the compliance architecture, documentation of every security decision, and complete ownership of your code and infrastructure.
Getting HIPAA Right From the Start
HIPAA compliance in custom software isn't a mystery. It's a set of specific, well-defined requirements that experienced development teams know how to implement. The hard part isn't knowing what to do. It's doing it consistently across every feature, every integration, and every edge case in your healthcare workflow.
If you're building healthcare software, or if you have existing software that needs a compliance overhaul, we can help. We've done this across medical records systems, care coordination platforms, claims processing tools, and patient payment portals.
Every healthcare organization has different workflows, different risk profiles, and different compliance requirements. We start by understanding yours.
