Big news! After 16 years, the FDA is changing its guidance on the software documentation needed in regulatory submissions. The new draft guidance, “Content of Premarket Submissions for Device Software Functions,” was announced last month. When finalized, this new guidance will supersede the Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices (May 2005). 

This new draft guidance is quite different from the 2005 guidance. Here are some key changes in it:

This new draft guidance is quite different from the 2005 guidance. Here are some key changes in it:

  • The documentation will no longer be determined by software Level of Concern (Minor / Moderate / Major); instead, it will be determined as needing Basic or Enhanced level of documentation (based on the software’s risk).  The Enhanced level is required if any of the following apply:
    • Class III or combination device
    • Device tests blood donations or determines donor-recipient blood compatibility.
    • Device software functions could present a probable risk of death or serious injury (pre-mitigations)
  • The Device Hazard Analysis is replaced by the device’s Risk Management File documents.
  • The new guidance allows for the declaration of conformity to the IEC 62304 medical software standard.
  • The new guidance has more explanations of what is required in each type of software document, such as the architecture diagram.

The Software Landscape

At a medical device company, there can be many types of software, and it’s often confusing to know what are the regulatory requirements for each type and what documentation is needed.  The diagram below summarizes the different types of software with some examples of each. The types are split broadly into Product vs. Non-Product software because the regulations and standards are split that way (e.g., the IEC 62304 standard only applies to Product software). The regulated Product software is divided by safety classification (A/B/C).

For Non-Product software, it can be difficult to know what is regulated and what is not.  The key consideration here is determining if the software automates or otherwise supports a regulated process. For example, software that manages document approvals and changes for Doc Control is regulated and needs to be validated for its intended use.

*Enforcement discretion means that FDA regulations apply but the FDA has decided not to enforce them for certain low risk software.

Confusingly, many modern medical devices, especially in digital health, include both regulated and non-regulated product software.  For guidance on managing a mix of regulated and non-regulated software functions, see the FDA guidance Multiple Function Device Products: Policy and Considerations (JUL 2020).
