How to submit prior authorization

If the member received anti-emetic drugs in an outpatient setting for a cancer diagnosis from May 1, 2021, through July 31, 2021, you DO NOT need to submit a prior authorization request until a new anti-emetic drug will be administered.

We will authorize the anti-emetic drug the member was receiving prior to Aug. 1, 2021, and the authorization will be effective until Jan. 31, 2022, unless a change in treatment is needed.

Please complete all notifications online. Sign into the UnitedHealthcare Provider Portal using your One Healthcare ID and select the Prior Authorization and Notification tool. Once you are in the tool, select Oncology, and when prompted, answer the questions about the service type, member type and state. You can submit authorizations for anti-emetics on July 1, 2021, in advance of the Aug. 1, 2021, requirement.
