FDA issued a version of its “Refuse to Accept Policy for 510(k)s” dated 21-Feb-2019. This supersedes the prior 30-Jan-2018 version. As FDA guidance goes, this a short period of time between updates. It focuses on explaining the initial 15 day administrative completeness check, review initial questions, provision of a checklist for this administrative review which includes checking that if standards are referenced in any way their usage is explained, any device-specific guidance was addressed, electrical safety and EMC information is included if relevant.
The term Software is used many times in this guidance including that if software is included in the device the information requested in the FDA “Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices” and the associated Off-the-shelf software guidance (if relevant) is included. If a device does not contain software it must be clearly indicated that it does not.
