HIPAA-Compliant Software Development Checklist for HealthTech Startups

Introduction

You are building a healthcare product that handles protected health information (PHI).
You have confirmed that HIPAA applies to your product.

‍Now you need a concrete answer to the question every technical founder asks next: what does my software actually need to do to be compliant?

This article is that answer. It is a checklist, organized by the four areas that matter for HIPAA-compliant software development: technical safeguards, infrastructure, application design, and administrative policies. Each item is specific enough to assign to an engineer or add to a sprint backlog.

This is engineering guidance, not legal advice. Consult a healthcare compliance attorney for your specific situation. For the regulatory framework, see Momentum's HIPAA Compliance Guide for CTOs and the HIPAA Decision Tree. This checklist covers what to build.

HealthStack: HIPAA-Compliant Infrastructure in Days

Momentum's open source HealthStack Terraform modules reduce HIPAA-compliant infrastructure setup from weeks to days.

HealthStack is a set of pre-built, production-tested Terraform modules that deploy HIPAA and GDPR-compliant infrastructure on AWS. It handles the infrastructure checklist items covered in this article:

• VPC with network segmentation that isolates PHI workloads in private subnets
• Encryption configured by default using AWS KMS for data at rest and TLS for data in transit
• Audit logging through CloudWatch and CloudTrail with tamper-evident log storage
• Access controls via IAM roles with least-privilege permissions
• Monitoring and alerting pre-configured for security events and infrastructure health
• Automated backups with cross-region replication for disaster recovery

What HealthStack Covers vs. What You Handle

HealthStack automates the infrastructure layer: cloud configuration, network segmentation, encryption, logging, and monitoring. These are the items in the Infrastructure Checklist section above.

Your team remains responsible for the application layer: PHI data handling, authentication logic, session management, input validation, and API security. These are the items in the Application Checklist and Technical Safeguards Checklist sections.

Your team also remains responsible for the administrative layer: BAAs, incident response plans, workforce training, and risk assessments.

Infrastructure is the part of compliance that benefits most from automation and standardization. Application logic and organizational policies are specific to your product and cannot be generalized into a Terraform module.

Common Mistakes That Break HIPAA Compliance

After supporting 100+ healthcare deployments, Momentum's engineering team sees the same compliance failures repeatedly. These are operational gaps that exist in production systems that otherwise appear well-architected.

1. Storing PHI in services without a BAA

A team configures their database and cloud storage correctly, then sends PHI to an analytics platform or error tracking tool without a BAA. Every service that receives PHI needs a BAA. If the vendor does not offer one, the service cannot be used for PHI.

Common offenders: logging platforms, analytics tools, support chat widgets, marketing automation platforms, and third-party form builders.

2. Logging PHI in application logs or error tracking

A stack trace that includes a patient name. A debug log that prints the full API request body. An error message that contains a diagnosis code. These are breaches. Implement structured logging with PHI field masking at the framework level, not as something individual developers remember to do.

3. Sharing database credentials instead of using IAM roles

Shared credentials make it impossible to attribute access to specific individuals, which violates the unique user identification requirement. Use IAM-based database authentication (supported by AWS RDS, Aurora, and equivalents on other cloud providers) so every access is tied to a specific identity.

4. Skipping encryption for internal services

"It's only internal traffic" is not a valid justification. Service-to-service communication within your VPC should use TLS, and internal databases should enforce encrypted connections.

5. Using consumer-grade tools for PHI communication

Personal Gmail accounts, free Slack workspaces, consumer Dropbox, and SMS messages are not HIPAA-compliant channels for PHI. If your team discusses patient cases or shares PHI for debugging, those communications need to happen on platforms with BAAs and appropriate access controls.

6. Not testing backup restoration

Having automated backups is necessary but not sufficient. If you have not tested restoring from those backups within the last 90 days, you do not know whether your disaster recovery plan works. Schedule quarterly restoration tests and document the results.

Start Your HIPAA Compliance Implementation

This checklist provides the technical foundation for HIPAA-compliant software development. The work is in implementing each item, validating it through testing, and maintaining it as your product evolves.

If you are building a healthcare product and need engineering support for HIPAA-compliant development, Momentum's team has implemented these requirements across 100+ healthcare deployments. Explore our HIPAA compliance services to see how we can help you build on a compliant foundation from day one.
