From the Wikipedia for the ninth season:

> Lawrence considered the eighth season to be the end of the show Scrubs, going so far as to ask ABC if he could change the name to Scrubs Med School. ABC declined, but Lawrence still advised fans to treat it as a new show, even putting a caption under the "Created By" on the X-ray in the opening sequence saying [Med School]

So the showrunner treated it like a spinoff but the network wanted to keep the name.
