What Documentation Is Required for an FDA 510(k) Submission? Complete 2026 Guide

Quick Answer: What Documents Do You Need for an FDA 510(k)?

An FDA 510(k) submission must contain enough evidence for the Food and Drug Administration to determine that a medical device is substantially equivalent to a legally marketed predicate. The FDA 510(k) documentation requirements vary by device, but most submissions include administrative information, an Indications for Use statement, a detailed device description, predicate comparison, labeling, performance testing, risk management evidence, and software documentation when applicable.

For connected or software-enabled devices, cybersecurity can become one of the most important parts of the submission. FDA’s February 2026 cybersecurity guidance recommends structured evidence covering cybersecurity risk management, security architecture, threat modeling, controls, testing, labeling, and lifecycle management. Devices meeting the statutory definition of a cyber device under Section 524B must also satisfy specific cybersecurity requirements, including an SBOM and postmarket vulnerability-management processes.

What Is a 510(k) Submission?

A 510(k), formally called a Premarket Notification, is used to demonstrate that a new medical device is substantially equivalent to a legally marketed predicate device.

FDA considers whether the new device has the same intended use as the predicate and whether differences in technological characteristics raise different questions of safety and effectiveness. If there are differences, the manufacturer must provide appropriate performance evidence showing that the device remains as safe and effective as the predicate.

Since October 2023, most 510(k) submissions to FDA’s Center for Devices and Radiological Health are prepared using the electronic Submission Template and Resource, or eSTAR. eSTAR organizes the submission into structured sections and prompts sponsors to provide required information.

What Administrative Documents Are Required for a 510(k)?

The submission may include applicant and correspondent details, submission type, device classification information, prior FDA interactions, applicable standards, a cover letter, a Truthful and Accurate Statement, and either a 510(k) Summary or a 510(k) Statement.

The device name, model number, software version, manufacturer identity, and submission owner should remain consistent throughout the file.

What Should the Indications for Use Statement Include?

The Indications for Use statement explains what the device is intended to do, the patient population or clinical condition it addresses, and the environment or circumstances in which it is intended to be used.

It should match the proposed labeling and claims supported by testing because it influences classification, predicate selection, and substantial equivalence.

What Device Description Documentation Does FDA Expect?

The device description should enable an FDA reviewer to understand the product without relying on assumptions.

Depending on the device, documentation may include engineering drawings, photographs, block diagrams, dimensions, materials, components, accessories, operating principles, energy sources, user interfaces, software functions, communication interfaces, network connections, and cloud dependencies.

For multiple models or configurations, explain the differences and identify which configuration was tested. Connected products should also show external applications, cloud services, hospital systems, and accessories.

How Should You Document Predicate Comparison and Substantial Equivalence?

The predicate comparison is the central regulatory argument of the 510(k).

Manufacturers should identify an appropriate legally marketed predicate and provide a structured comparison covering intended use, indications, technological characteristics, materials, design, operating principles, performance, software, connectivity, sterilization, and other relevant features.

Differences should be addressed directly.

A stronger submission explains why each difference does not raise a different question of safety or effectiveness, or provides performance evidence showing that the difference has been adequately evaluated.

What Performance Testing Documentation Is Required?

Performance testing should support device specifications and the substantial equivalence argument.

Depending on the product, FDA may expect bench testing, electrical safety, electromagnetic compatibility, mechanical testing, biocompatibility, sterilization validation, packaging, shelf-life evidence, usability or human factors testing, wireless coexistence testing, software verification, animal testing, or clinical data.

Every report should clearly state its objective, test method, sample configuration, acceptance criteria, results, deviations, and conclusion.

Where applicable, identify FDA-recognized consensus standards and explain any differences between tested and final commercial configurations.

What Software Documentation Is Required for a 510(k)?

If the device includes software, the submission should provide software documentation appropriate to the device.

Typical evidence includes a software description, architecture, software requirements, system requirements, risk analysis, verification and validation results, revision history, unresolved anomaly information, and documentation explaining how software functions interact with the medical purpose of the device.

For SaMD, mobile applications, cloud platforms, and embedded software, reviewers should understand interactions with users, external systems, data, and safety-relevant functions.

Which 14 Cybersecurity Documents Should Manufacturers Prepare?

For devices with cybersecurity risk, FDA’s guidance identifies multiple forms of cybersecurity evidence that may be relevant to a premarket submission. For cyber devices, Section 524B adds specific statutory requirements.

The following 14 documents or evidence artifacts provide a practical readiness framework.

1. Security Architecture

The security architecture explains system components, interfaces, trust boundaries, assets, communication pathways, user roles, and implemented security controls. FDA recommends security architecture views that help reviewers understand the device globally, including updateability, multi-patient impact, and relevant security use cases.

2. Threat Modeling Report

A threat model identifies credible attack paths, threat actors, assets, entry points, trust-boundary crossings, and potential consequences. It should reflect the final device architecture and connect identified threats with security requirements and controls.

3. Software Bill of Materials

An SBOM identifies software components used in the device. For covered cyber devices, Section 524B requires an SBOM containing commercial, open-source, and off-the-shelf software components.

4. Software Level of Support and End-of-Support Information

Manufacturers should document software maintenance expectations, support status, end-of-support dates, patch availability, and plans for components that become obsolete.

5. Penetration Testing Report

Penetration testing provides practical evidence about the effectiveness of cybersecurity controls.

Testing may cover firmware, device interfaces, authentication, authorization, APIs, mobile applications, cloud services, communication protocols, update mechanisms, and other relevant attack surfaces.

The report should identify scope, methodology, configuration, findings, evidence, and remediation.

6. Retesting Report

A retesting report confirms whether previously identified vulnerabilities were successfully remediated.

Map each original finding to its corrective action and verified status.

7. Security Assessment of Unresolved Anomalies

Known unresolved software anomalies should be evaluated for cybersecurity implications.

The assessment should explain exploitability, possible impact, existing controls, residual risk, and the rationale for releasing the device with the anomaly unresolved.

8. Cybersecurity Risk Assessment

The cybersecurity risk assessment evaluates threats and vulnerabilities affecting confidentiality, integrity, availability, device functionality, and safety.

9. Safety and Security Risk Assessment of Vulnerabilities

Cybersecurity findings should be evaluated for potential clinical and patient-safety impact.

A useful traceability chain is: vulnerability, exploitation pathway, compromised device function, hazardous situation, risk control, verification, and residual risk.

10. Cybersecurity Controls Documentation

Cybersecurity controls documentation describes safeguards such as authentication, authorization, encryption, secure communication, least privilege, secure boot, code signing, update integrity, logging, monitoring, recovery mechanisms, and data integrity protections.

Each control should be linked to identified threats and verification evidence.

11. Cybersecurity Risk Management Report

The cybersecurity risk management report consolidates the security evidence into a coherent record showing how cybersecurity risks were identified, assessed, controlled, verified, and accepted.

12. Cybersecurity Labeling

Cybersecurity labeling provides information necessary for secure deployment, operation, maintenance, and decommissioning.

This can include network requirements, secure configuration, authentication responsibilities, software update instructions, backup and recovery guidance, logging capabilities, supported software information, and security contact details.

13. Cybersecurity Metrics

Cybersecurity metrics provide measurable information about security performance.

Examples may include unresolved findings, remediation timelines, security requirement verification coverage, vulnerability trends, component support status, or patch performance.

14. Cybersecurity Risk Management Plan

The cybersecurity risk management plan defines how cybersecurity risks will be governed throughout the product lifecycle.

For covered cyber devices, Section 524B requires plans and processes for monitoring, identifying, and addressing postmarket vulnerabilities and exploits, providing reasonable assurance of cybersecurity, and making appropriate updates and patches available.

FDA 510(k) Cybersecurity Documentation Checklist

Are All 14 Cybersecurity Documents Legally Mandatory for Every 510(k)?

No.FDA does not publish a universal rule stating that every 510(k) must contain fourteen separately titled cybersecurity documents.

Applicability depends on the device, its architecture, cybersecurity risk, software functions, and whether it meets the statutory definition of a cyber device.

Section 524B creates specific legal requirements for cyber devices. FDA’s February 2026 cybersecurity guidance provides broader recommendations for cybersecurity documentation in premarket submissions involving cybersecurity risk.

Manufacturers should perform a device-specific assessment rather than create generic files.

What Documentation Gaps Commonly Trigger FDA Questions?

Frequent gaps include architecture diagrams that do not match the tested system, incomplete threat models, weak traceability between risks and controls, penetration testing without remediation evidence, outdated SBOMs, unresolved vulnerabilities without clinical analysis, and cybersecurity labeling that conflicts with actual deployment assumptions.

Late cybersecurity testing can force software changes, repeat verification, and document updates shortly before filing.
