A single software defect has the potential to endanger patient safety while also leading to the failure of your product launch. Medical device software development requires programmers to do more than write error-free code because of its critical nature.
Market Research Future predicts the software-as-a-medical-device sector will expand from USD 5.56 billion in 2026 to reach USD 80.12 billion by 2035 through a 34.5% annual growth rate.
The budget for software development starts at $150K for basic programs and reaches above $2M for developing complicated firmware systems. The FDA requires all organisations to follow its established rules without any exceptions.
The guide presents information about classification, compliance, process, testing, tools, AI, and cost to help you plan medical device software development while preventing expensive backtracking.
What Is Medical Device Software Development?
Medical device software development follows a regulated process which includes software design, construction, testing, and maintenance for applications that perform patient diagnosis, monitoring, and treatment either as independent programs or as device firmware.
SaMD vs SiMD vs General Wellness Software
- SaMD: Standalone software performing a medical function, such as AI imaging triage.
- SiMD: Embedded firmware running a physical device, such as an infusion pump.
- General wellness: Low-risk apps without medical claims, such as step counters.
Who Is a Software as a Medical Device Developer?
A medical software developer who builds clinical software under IEC 62304 operates as a medical device software developer. This developer uses their engineering abilities together with their understanding of medical regulations and risk assessment for medical software development.
Medical Device Software Classification: FDA Classes and IEC 62304 Safety Levels
The classification system determines which regulatory path you must follow, while it also determines your documentation needs and your financial expenses. The system uses two separate systems for operation: the FDA device class, which controls market entry, and the IEC 62304 safety class, which determines software development requirements.
- FDA Class I: Most low-risk medical devices under FDA Class I receive 510(k) exemption but remain subject to general controls and quality system requirements.
- FDA Class II: The FDA classifies moderate-risk medical devices as Class II, which includes most SaMD products that require 510(k) or De Novo clearance.
- FDA Class III: Medical devices that pose high risk or need implantation require premarket approval through clinical evidence evaluation.
- IEC 62304 Class A: A software failure in IEC 62304 Class A creates no danger to people, so it requires the minimum amount of documentation.
- IEC 62304 Class B: This failure can cause moderate injury, so the system needs documented architecture, and developers must do unit testing and integration testing with traceability.
- IEC 62304 Class C: Its failure can cause fatal injuries or severe bodily harm, so it requires the highest level of design, testing, and documentation.
Medical device software risk management depth depends on safety class requirements. Medical app development projects that start as basic applications must follow Class II regulations.
Regulatory Standards Every Medical Device Software Developer Must Follow
There is no unique regulation or law covering medical software development. Developers must be able to demonstrate that the software lifecycle and quality control procedures were implemented and followed. There are many standards and regulations that developers must comply with, including those relating to security, risk, and privacy. From the beginning, developers must be able to produce documentation and evidence to support their software and the processes used to develop that software.
A. IEC 62304, ISO 13485 and ISO 14971
- IEC 62304: This starts with planning and continues through maintenance activities. The level of control depends on the safety class according to IEC 62304 standards.
- ISO 13485: Need organisations to develop a quality management system which tracks all activities and handles all problems before they start producing their code.
- ISO 14971: All software requirements and test cases to their corresponding hazards and the protective measures which reduce the remaining risk.
B. FDA QMSR, Section 524B Cybersecurity and EU MDR
- FDA QMSR: The FDA QMSR will become operational in February 2026 to establish an equivalence between 21 CFR Part 820 and ISO 13485 standards.
- Section 524B: The cyber devices need to present either a secure design plan along with the SBOM and vulnerability management plan, or they must face rejection of their risk assessment.
- EU MDR: Requires medical devices to obtain certification for use in Europe, but FDA approval does not grant automatic entry because IEC 62304 and ISO 14971 evidence remains valid for use.
Medical device software development companies with good reputations make these standards their standard practice during every development sprint. Healthcare data exchange should follow HIPAA standards when you combine them with these controls.
Medical Device Software Development Process Step by Step
The software development process needs to follow exact steps that maintain proper alignment between code, risk controls, and documentation to achieve full traceability from requirements to verification evidence and risk analysis.
- Planning and Software Development Plan: Fix the safety classification system together with the lifecycle framework and verification approach and toolset.
- Requirements, Architecture and Design: Develop requirements that can be tested through unique identification numbers and modular architecture to track all SOUP (software of unknown provenance) components.
- Implementation and Integration: Organisations need to follow coding standards, conduct document reviews, and create test-to-requirement links.
- Release and Post-Market Surveillance: The process requires formal sign-off before it moves forward to complaint handling and then to vigilance reporting and controlled updates.
- Agile in Medical Device Software Development: Agile works when each sprint needs to create verification artefacts which update both traceability and risk documentation.
A strong healthcare IT solutions partner applies exactly the same disciplined approach.
Medical Device Software Testing: Verification, Validation and Cybersecurity
Documented evidence is required for regulatory purposes. This includes the planning and execution of all device software tests. It requires traceability of all software testing back to the device software requirements.
1. Verification
Requirements for medical device software testing, including unit, system, and integration testing. Document the link between each test and the associated requirement ID.
2. Validation
Usability studies and clinical evaluation. These activities validate the requirements in relation to user needs.
3. Cybersecurity
Penetration, fuzz, and static analysis results form required Section 524B evidence.
4. Regression and SOUP checks
Changes to the device or software should be evaluated and tested for potential impacts. These should include tests related to existing vulnerabilities.
5. Connectivity testing
Wireless connectivity, particularly for mobile device connectivity, requires interface and data integrity tests. Experience in the area of IoT development is a resource of benefit.

| AI/ML stack | Model building and versioning | Python, TensorFlow, PyTorch, MLflow |
Plan early to develop interoperability by considering the overlap between EHR software, FHIR, and HL7.
AI Medical Device Software Developer: Building AI/ML-Enabled Devices
The AI medical device software developer needs to establish predictive software update processes that fulfil regulatory needs by using unaltered data and establishing continuous monitoring systems. The system needs to monitor itself at all times.
A. Predetermined Change Control Plans (PCCP)
- Pre-specified updates: The PCCP document establishes specific model update procedures which teams must follow to achieve validation after approval without needing to submit additional documents for every change.
B. Bias, Data Provenance and Post-Market Monitoring
- Bias evaluation: The evaluation process needs to assess how diagnostic and triage algorithms perform with different demographic groups during their testing phase.
- Data provenance: The data provenance requires organisations to record all training data origins and obtain proper consent for data use while following established labelling methods for each version of their models.
- Post-market monitoring: The monitoring system for post-market products tracks model changes which appear in actual use to create data that supports improvement initiatives.
Healthcare professionals need to understand how AI technology reshapes their diagnostic work and their monitoring operations.
Custom Software Development for Medical Devices: When Off-the-Shelf Fails
Standard, off-the-shelf software is typically not designed to satisfy the requirements for traceability, safety, and documentation from a regulator’s perspective. Custom software development for a medical device puts the user in control from the very first line of code.
1. Hidden Third-Party Code
Generic software platforms often contain undocumented components which create gaps for a SOUP (Software of Unknown Pedigree) analysis or findings for an audit.
2. Exact Intended Use Fit
Standard platforms force the user to work with their generic workflows, creating a disconnect between the device and its intended users. A custom device is the most efficient device for a clinician, reducing use errors and rework.
3. Controlled Integrations
Design, implement, and verify the connections with firmware, EHRs, and other cloud-based devices.
4. Early-stage R&D
Software research for medical devices is much faster and cheaper with early, tailored prototyping of software.
5. Clear Ownership
Control of software IP and design history record (DHR) submissions speeds regulatory filings.
There are numerous software developers in the marketplace who create devices. Some do it right and develop a great foundation of custom medical software that other developers in other industries adopt for regulated work.
How Much Does Medical Device Software Development Cost?
Medical device software development costs start at approximately $150K for a Class A SaMD MVP, but they can reach over $2M for sophisticated firmware systems and AI/ML devices. The pricing system bases its calculations on safety class, regulatory pathway, connectivity, cybersecurity requirements, and testing scope instead of counting features while excluding FDA fees, clinical studies, and EU notified body costs.
The cost for classification, compliance, and clinical risk management determines the costs instead of product features. The cost estimation process for medical device software development begins with these range figures, which you need to adjust according to your specific project requirements.
1. Medical Device Software Development Cost Estimate by Device Class
| Build Type | Pathway | Cost Range | Timeline |
| Class A SaMD MVP | 510(k) exempt | 150K–350K | 7–10 months |
| Class B SaMD | 510(k) | 350K–750K | 10–14 months |
| Class C SaMD | 510(k) / De Novo | 750K–1.5M | 14–20 months |
| SiMD (device firmware) | 510(k) / De Novo / PMA | 600K–2M+ | 18–30 months |
| AI/ML SaMD with PCCP | De Novo | 900K–2M+ | 15–24 months |
Excludes clinical validation, FDA fees, and EU notified body fees.
2. Medical Device Cost Breakdown: Engineering, QMS, Testing, Regulatory and Clinical
The medical device cost breakdown shows that engineering expenses appear as a single entry, but the combined expenses of quality work, testing, regulatory, and clinical activities exceed engineering costs.
| Cost Component | Typical Range |
| Engineering | Hours × rate (1,000 hours at $125/hour = $125,000) |
| QMS setup (from zero) | 30K–80K |
| Regulatory submission prep | 50K–250K |
| Clinical validation | 150K–500K+ |
3. MedTech Cost Breakdown: Software vs Hardware vs Compliance
A medtech cost breakdown should separate software (about 150K–2M+), hardware costs, device engineering fees, and compliance expenses, which range from tens of thousands up to more than $500K.
4. Medical Device Manufacturing Costs After Design Transfer
The medical device manufacturing costs start when the design transfer process finishes, and these costs exist independently of engineering fees because they cover tooling, moulds, per-unit components, assembly, and inspection under the ISO 13485-based quality management system.
5. FDA Fees and Hidden Costs: Most Quotes Skip
FDA fees will be $28,653 for a regular 510(k) submission and $7,163 for a submission from a small business. A submission will be $191,020. Quotations regularly overlook the need to establish a quality management system and fail to consider the need for SOUP risk analysis and do not provide for the requirements for evidence of compliance with standards on cybersecurity and post-market surveillance and clinical evaluations. Development of an application for non-regulated use in the healthcare sector is less costly, due primarily to the overhead requirements related to the regulatory process.
Outsource Medical Device Software Development: In-House vs Partner
First-time teams in the medtech space will usually look to external partners to develop their software, primarily because a seasoned partner will already have a robust, audited, ready-to-go quality system in place and the required regulatory documentation know-how to guide a medtech company through its development cycles.
| Factor | In-House Team | Outsourced Partner |
| QMS and documentation | Must build or already own | Uses an established QMS |
| Regulatory experience | Depends on past clearances | Brings submission track record |
| Cost structure | Salaries, tools, audits | Phase-based or hourly |
| Best for | Teams with prior FDA clearances | First regulated product |
Medical Device Software Consulting: When to Bring in Regulatory Experts
Bring in software consultants as early as possible (preferably before fixing your device’s architecture) to verify your device’s classification and decide whether to pursue the 510(k) or de novo pathways. Doing so will prevent costly retrofitting of your device’s quality system.
How to Evaluate a Medical Device Software Development Partner
Whether you choose a medical device software development company in the USA or offshore, compare medical device software development companies on:
- A set of redacted plans, risk files, and test protocols.
- A list of previous FDA submissions that fall under the specific pathway you’re targeting.
- Experience with Section 524B (Cybersecurity for Medical Devices)
- Ownership of the device’s source code and design documents.
- An itemised list of estimates for each stage of development (with exclusions clearly marked).
A proven healthcare software development company is a safer shortlist starting point.
