The first nine seasons of the series debuted on Crackle and are currently streaming on Netflix.
Season 10 is scheduled to premiere July 6 on Netflix
Netflix confirmed Thursday that Lewis' episode will be part of Season 10.
"As I've said many times, if you don't get Jerry Lewis, you don't understand comedy. Spending an afternoon with him a couple of months ago in Vegas for Comedians in Cars was a comedy life moment for me," Seinfeld captioned an Instagram photo of him laughing with Lewis, while riding in a convertible with the top down.
Seinfeld shared the photo in August as he paid tribute to Lewis after his death.
