Building connected medical devices means navigating FDA device regulations and HIPAA data requirements simultaneously. Here is how to avoid the compliance maze.
August 28, 2025 11 min read
Your startup is building a connected blood pressure monitor. The hardware captures patient vitals. The software transmits them to a mobile app. The cloud stores them for physician review.
You have just stepped into one of the most complex compliance environments in technology: the intersection of FDA medical device regulations and HIPAA data protection requirements. Each regulatory framework is demanding on its own. Together, they create a matrix of requirements that catches founders off guard.
The hardware must satisfy FDA safety and efficacy standards. The software qualifies as a medical device in its own right. The data pipeline must protect patient privacy under HIPAA. A failure in any dimension stops your product.
This is not theoretical complexity. Connected healthcare devices face rejection rates and delays that dwarf traditional software products. Understanding the dual compliance landscape before you build determines whether you reach market or stall in regulatory review.
Understanding the Two Regulatory Frameworks
The FDA and HIPAA serve different purposes and govern different aspects of your product.
FDA regulations ensure medical devices are safe and effective. The FDA cares whether your product works correctly, does not harm patients, and does what it claims. Their jurisdiction covers the device itself, including both hardware and software that affects diagnosis, treatment, or patient health.
HIPAA regulations protect patient health information. HIPAA cares about how you collect, store, transmit, and secure protected health information (PHI). Their jurisdiction covers any entity that handles patient data, regardless of whether they also make medical devices.
A connected medical device falls under both. The device hardware and software face FDA scrutiny. The data handling faces HIPAA scrutiny. Neither framework exempts you from the other.
This creates situations where compliance with one framework conflicts with the other. Aggressive security measures like frequent patching or restrictive network controls may satisfy HIPAA but interfere with FDA requirements around device performance. Manufacturer update processes approved by the FDA may not meet HIPAA technical safeguards. You must thread both needles simultaneously.

The FDA Device Classification System
The FDA classifies medical devices into three risk categories. Classification determines your regulatory pathway and documentation requirements.
Class I (Low Risk): General controls only. Most Class I devices are exempt from premarket notification. Examples include bandages, tongue depressors, and basic hospital beds. Connected IoT devices rarely qualify.
Class II (Moderate Risk): General controls plus special controls. Requires 510(k) premarket notification demonstrating substantial equivalence to a predicate device. Most connected healthcare devices fall here. Examples include powered wheelchairs, pregnancy tests, and many diagnostic instruments.
Class III (High Risk): General controls, special controls, and premarket approval (PMA). Life-sustaining or life-supporting devices, or devices without predicates. Examples include pacemakers, artificial hearts, and implantable defibrillators.
The 510(k) pathway is the most common for IoT healthcare products. You must demonstrate that your device is substantially equivalent in intended use and technological characteristics to a legally marketed predicate device.
Common rejection reasons for 510(k) submissions include:
Inadequate risk management documentation
Insufficient software validation and verification testing
Failure to clearly demonstrate substantial equivalence
Poorly organized submission documents
Missing or incomplete cybersecurity considerations
For software components specifically, the FDA uses a risk-based documentation approach. Basic Documentation suffices for minimal-risk software. Enhanced Documentation is required for software where malfunctions could lead to hazardous situations.
Software as a Medical Device (SaMD)
Your connected device likely contains software that the FDA considers a medical device in its own right.
SaMD is defined as "software intended to be used for one or more medical purposes that performs these purposes without being part of a hardware medical device." If your mobile app analyzes patient data and provides diagnostic recommendations, that app is a medical device regardless of the hardware.
SaMD documentation requirements include:
Architecture documentation describing system design
Risk analysis identifying failure modes and mitigations
The documentation level depends on risk. Software providing information to support clinical decisions requires more extensive documentation than software providing general wellness information.
For AI-enabled devices, the FDA now allows Predetermined Change Control Plans (PCCP). You can predefine the boundaries of acceptable algorithm changes in your initial submission. Updates within those boundaries do not require new submissions. This is crucial for ML-based products that improve over time.
The 2025 HIPAA Security Rule Updates
HIPAA requirements are strengthening in response to healthcare cybersecurity threats.
The 2025 updates introduce stricter vulnerability scanning and risk management requirements. Proposed modifications to the Security Rule would be the first significant changes since the standards were initially issued.
Risk analysis identifying threats and vulnerabilities
Risk management implementing security measures
Workforce security training
Contingency planning for incidents
Physical Safeguards:
Facility access controls
Workstation security
Device and media controls
Connected devices create specific challenges. Edge devices collecting PHI must implement appropriate safeguards. Data transmission from device to cloud must be encrypted. Cloud storage must enforce access controls. Every point in the data pipeline faces HIPAA requirements.
Where the Frameworks Conflict
The tension between FDA and HIPAA manifests in concrete scenarios.
Patching and updates. HIPAA encourages aggressive patching to address vulnerabilities. FDA requires that updates not affect device safety and efficacy. A software update that closes a security hole might also change device behavior in ways requiring new FDA review. You cannot freely patch medical device software the way you patch a web application.
Logging and audit trails. HIPAA requires detailed audit trails of PHI access. Some devices have limited storage for logs. Logging requirements may conflict with device performance constraints approved by FDA.
Network segmentation. HIPAA best practices recommend micro-segmenting networks so devices only communicate with approved services. This zero-trust networking can conflict with FDA-approved device behavior if the device expects different network access.
Vendor management. Healthcare delivery organizations (HDOs) deploy FDA-cleared devices but may fail to integrate them into enterprise logging or access control systems. The device manufacturer satisfies FDA requirements. The HDO creates HIPAA gaps by failing to implement proper controls around the device.
The solution is unified compliance strategy. You cannot approach FDA and HIPAA as separate workstreams that you merge at the end. The architecture must satisfy both from the design phase.
Cybersecurity Requirements for Connected Devices
The FDA finalized cybersecurity guidance in September 2023 requiring manufacturers to submit cybersecurity risk assessments including threat modeling, Software Bills of Materials (SBOMs) listing third-party components, and postmarket vulnerability management processes.
This guidance classifies cybersecurity issues as potential quality defects. Inadequate security is grounds for enforcement action, not just a compliance gap.
Required documentation includes:
Threat models identifying attack vectors
SBOMs listing all software components with versions
Secure update mechanisms for deploying patches
Postmarket vulnerability management processes
Incident response procedures
The emphasis on SBOMs reflects the interconnected nature of modern software. Your device likely includes open-source components, third-party libraries, and cloud dependencies. Each creates potential vulnerabilities. The FDA wants to know what is in your software so they can assess risk.
Practical Compliance Architecture
Certain architectural patterns help satisfy both FDA and HIPAA requirements.
Edge security gateways. Funnel all device traffic through hardened gateways that enforce firewall rules, protocol filtering, and intrusion detection. This creates a single point where you can implement HIPAA security controls without modifying FDA-approved device behavior.
Zero-trust networking. Micro-segment networks so each device only communicates with approved services and peers. Implement this at the network level rather than in device software to avoid FDA implications.
Data minimization. Collect only the PHI you need. Store it only as long as required. The less data you handle, the smaller your HIPAA attack surface.
Encryption everywhere. Encrypt data at rest and in transit. Use TLS for network communications. Encrypt local storage. This is table stakes for both FDA and HIPAA.
Separation of concerns. Isolate FDA-regulated device functionality from HIPAA-regulated data handling. The device captures data. A separate system manages PHI. Changes to data management do not affect device behavior.
The Documentation Burden
Connected healthcare devices require extensive documentation for both frameworks.
These documentation requirements interact. Your FDA risk analysis should address HIPAA-relevant threats. Your HIPAA risk assessment should account for device-specific vulnerabilities.
Products fail dual compliance in predictable ways.
Treating FDA and HIPAA as sequential. Teams complete FDA clearance, then turn to HIPAA. They discover the FDA-approved architecture cannot satisfy HIPAA requirements. Redesign delays launch by months.
Underestimating software documentation. Hardware-focused teams assume software is a small part of the submission. SaMD documentation requirements are extensive. Insufficient software documentation is a top rejection reason.
Ignoring postmarket obligations. FDA clearance is not the finish line. Both FDA and HIPAA require ongoing monitoring, vulnerability management, and incident response. Failing to plan for postmarket obligations creates compliance gaps after launch.
Assuming cloud providers handle HIPAA. AWS, Azure, and GCP offer HIPAA-eligible services. This does not make your product HIPAA-compliant. You must implement controls using those services correctly. The provider gives you tools. You bear responsibility.
Neglecting vendor agreements. Every third-party touching PHI needs a Business Associate Agreement. Missing BAAs with cloud providers, analytics services, or support tools creates compliance gaps.
Risk Management as a Unifying Framework
ISO 14971 provides a risk management framework that can satisfy both FDA and HIPAA requirements.
The standard requires:
Risk analysis identifying hazards and estimating risk
Risk evaluation determining acceptability
Risk control implementing mitigation measures
Residual risk evaluation assessing remaining risk
Risk management report documenting the process
Production and post-production activities monitoring for new risks
Applying ISO 14971 comprehensively addresses FDA safety requirements and HIPAA security requirements through a single process. The threats differ (patient harm from device malfunction versus privacy breach from data exposure), but the methodology is consistent.
Building Your Compliance Team
Dual compliance requires specialized expertise.
Regulatory affairs specialist. Someone who understands FDA submission requirements, can navigate predicate device identification, and knows how to structure documentation for approval.
Privacy and security expert. Someone who understands HIPAA technical and administrative requirements, can conduct risk assessments, and knows healthcare-specific security controls.
Quality assurance. Someone who can implement quality management systems, manage documentation, and ensure ongoing compliance.
Early-stage startups often cannot hire all three roles. Options include:
Regulatory consultants who guide FDA submissions
HIPAA consultants who conduct assessments and implement controls
Fractional compliance leadership through CTO-as-a-Service arrangements
The expertise costs money. The alternative, submitting inadequate documentation, costs more through rejection, delay, and rework.
The Timeline Reality
Connected healthcare device development takes longer than founders expect.
FDA 510(k) review: Average review time is 90-180 days after submission. This assumes your submission is complete. Deficiency letters requesting additional information extend timelines significantly.
Submission preparation: Compiling a quality 510(k) submission takes 3-6 months of focused work. Software documentation is often the bottleneck.
HIPAA implementation: Implementing appropriate controls, training staff, and documenting compliance takes 1-3 months for simple products, longer for complex ones.
Total timeline: From starting development to market launch, plan for 18-24 months minimum. Complex products take longer.
For startups building MVPs in healthcare, this timeline affects everything: fundraising, hiring, competitive dynamics. Factor it into planning from the beginning.
Strategic Recommendations
For startups entering connected healthcare:
Start with regulatory strategy. Before building, understand your classification pathway. Identify predicate devices. Understand what documentation you need. This informs architecture decisions.
Design for both frameworks. Architecture choices made early are expensive to change later. Build with FDA and HIPAA requirements in mind from day one.
Document as you go. Reconstruction documentation after the fact is painful and error-prone. Maintain design history files, risk analyses, and compliance documentation throughout development.
Engage experts early. A few thousand dollars spent on regulatory consulting before you build saves tens of thousands in rework. Do not discover compliance requirements during submission review.
Plan for postmarket. Launch is not the end. Budget ongoing compliance costs: vulnerability monitoring, incident response, adverse event reporting, periodic risk reassessment.
The dual compliance environment is demanding. Products that navigate it successfully have genuine competitive moats. Competitors face the same barriers. If you can get through, others will struggle to follow.
