Cleared doesn't say which track it took

A cleared device’s public record carries a K-number, a decision date, an applicant, a product code. It does not carry which of FDA’s three 510(k) programs got it there — and the three programs review very different amounts of new evidence.

One regulation, three programs

Every premarket notification answers the same question under 21 CFR Part 807, Subpart E: is this device substantially equivalent to a predicate already on the market. How a submitter is allowed to answer it depends on which of three programs the 510(k) goes in under. A Traditional 510(k)is the original form — the full substantial-equivalence case, built under 807.87 from scratch. FDA created two narrower tracks in 1998 and split their guidance into two separate documents in 2019. A Special 510(k)covers a manufacturer’s own change to its own already-cleared device, and lets the firm rely on the design-control file it already built — the risk analysis and the verification and validation it already ran — instead of resubmitting a full new case. An Abbreviated 510(k)covers a device whose performance can be shown against an FDA guidance document, a set of special controls, or a recognized consensus standard, rather than against a specific predicate’s own bench data.

The record keeps the outcome, not the path

None of that distinction survives into the public dataset. openFDA’s clearance feed, and FDA Radar’s own ingestion of it, keep the K-number, applicant, device name, product code, decision code and description, the review panel, and two dates — received and decided. Which program the submission went in under is not one of the fields either side stores. Two clearances can share a decision date and a product code and have gone through entirely different reviews — one a Traditional filing built on new bench data against a competitor’s predicate, the other a Special 510(k) leaning on a firm’s own five-year-old design file. The public record cannot tell you which is which.

A decision date says a device cleared. It says nothing about what FDA read to reach it.

What this doesn’t change

None of this says which program a specific competitor’s filing used, or whether a Special or Abbreviated route was even available to a specific device — that determination sits with the submission itself, not with a public dataset three fields short of the answer. Per what FDA Radar monitors and how often, this is regulatory intelligence about a gap in the public record, never regulatory advice about which program a specific filing used or should have used.
