Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsGoodwill ImpairmentOn October 11, 2022, our Evolent Health Services segment was notified by Bright Health Group that it intended to exit its Individual and Family lines of business. Due to an expected decrease in projected future cash flows which could impact our estimated fair value, our existing goodwill in the EHS segment may require an adjustment. Such adjustment could be material. As of the date of this filing, the Company has not yet completed the analysis due to the complexities and time involved in determining the implied fair value of the goodwill. The analysis will be completed in the fourth quarter of 2022. As of September 30, 2022, goodwill in our EHS segment is $214.2 million. If the fair value of the EHS segment is determined to be less than the carrying value, an adjustment to goodwill will be required, and such amount could be material.
