$TDOC Teledoc is currently negotiating with UnitedHealth Group $UNH to offer telehealth as a benefit in some of its plans. Baird analyst Matthew Gillmor says that a deal with the U.S.'s largest health insurer would be an important validation of Teladoc's offering and serve as a positive catalyst for the stock. Additionally, Medicare Advantage plans with over 20 million members in 2018 will be able to include virtual care in their bids for the 2020 plan year. A partnership with CVS Health $CVS to incorporate Teladoc's platform into its app is gradually rolling out during 2019.
