Software as a Medical Device (SaMD)
Software as a Medical Device is software intended for a medical purpose that runs independently of dedicated hardware, such as a diagnostic algorithm or imaging analysis tool. Regulators classify and review it by risk, separate from software embedded in devices.
What is Software as a Medical Device (SaMD)?
Software as a Medical Device (SaMD) is software created for a medical purpose that performs its function on its own, without being part of a specific piece of hardware. Examples include algorithms that analyze images, detect conditions, or otherwise inform diagnosis and treatment.
What sets SaMD apart is that the software itself is the medical device, rather than code embedded inside a physical instrument. It can run on general computing platforms such as servers, phones, or cloud environments while still serving a regulated medical function.
Why does SaMD matter to regulators and providers?
Regulators classify and review Software as a Medical Device according to the level of risk it poses, applying greater scrutiny to software that informs higher-stakes clinical decisions. This risk-based approach treats standalone medical software distinctly from software merely built into a device.
As clinical algorithms and analytic tools become more common in care delivery, clear rules for SaMD help ensure these products are safe and effective before they influence patient care. For providers adopting such tools, understanding their regulatory status supports responsible and compliant use.
