Variable Interest Entity [Line Items]
Variable Interest Entity, Financial or Other Support, Reasons	The Company holds a variable interest in Talkspace Provider Network, PA (“TPN”) and seven affiliated professional corporations (“PC entities”). The Company evaluates whether an entity in which it has a variable interest is considered a VIE. VIEs are generally entities that have either a total equity investment that is insufficient to permit the entity to finance its activities without additional subordinated financial support, or whose equity investors lack the characteristics of a controlling financial interest (i.e., ability to direct the activities of the entity that most significantly impact the entity's economic performance through voting rights and a right to receive the expected residual returns of the entity or an obligation to absorb the expected losses of the entity).
