De Novo Reviews

Review Times At a Glance

De Novo reviews are generally longer than 510(k)s.  Over time, the review times have decreased, but the average is still closer to what we see with original PMAs.

Most are submitted directly, although there are still a few that are Post-NSE.

Less than half of De Novo submissions logged in are eventually approved.  The longer review times mean that we wait longer to really see the success rate.

Note that in 2018, one outlier (DEN070001) in MI, drives their average higher.  Without the outlier, MI had an average review time in 2018 of 207 days.
