Oscar Health in California: dispute windows have lapsed (verified)
Oscar Health exited the Covered California market at the end of 2023, and its current provider manual no longer lists California in its dispute-window table. With Oscar’s last California explanations of payment issued around 2024, the dispute windows tied to those payments have effectively lapsed.
Oscar’s California entries are therefore retained in our dataset as historical runout records only, and no current deadline values are published here. The source of record for the historical rule:
