Basically you would start with the Product Code for the product you are looking at that gives an indication for the Class of device and whether a 510(k) is required or not. The FDA has done a great job with the database
Product Classification with the information there about each device types. Probably outside of this discussion, but there are devices unclassified, De Novo, and whether a device is a medical device or not. Now there are a small number of devices that are Class I requiring a 510(k) and a few that are Class II that are 510(k) Exempt. You are correct in understanding that a 510(k) Exempt device that needs a 510(k) is because it has exceeded the limitations under section 8xx.9. This basically means that if the device has indications, features, or functionality that do not fall under the regulation number or product code then it "exceeds" the regulation. As a quick example, if there is a device indicated for 'x' that is 510(k) Exempt, but then a change is made to add indication 'y' (claim) and feature 'z' that exceeds the regulation, then a new 510(k) would be needed.

Recently I have been doing research on 510k exemptions and how they work.
My understanding is that as long as a new product complies with the Regulation Number and follows 21 CFR 890.9 it can be registered and marketed without 510k clearance in the US.
My question arises after seeing a 510k clearance for a product after the exemption had occurred. The product must have needed clearance due to not conforming with all criteria of the 21 CFR 890.9 document.
I read through a blog post found at 510(k) Exemption - What's Actually Exempt Part II that has a quote from the FDA saying "When a company submits a 510(k) for a device under a 510(k) exempt regulation, it is because the device exceeded the limitations of exemption for that regulation. If the device is then found substantially equivalent, the technology and/or indications newly cleared within that 510(k) would then expand the limitations of exemption within that regulation".
My question is with the phrasing of "expanding the limitations" quote. Does a post-exemption 510k clearance expand the indications for use/Fundamental Scientific Technology for all products that come after? Am I understanding that correctly?
-Thanks!
