The pre-authorization process generally involves the following steps: 1. Consultation: Your oncologist consults with you and recommends a treatment plan. 2. Submission: Your healthcare provider submits a pre-authorization request to your insurance company, including all necessary medical documentation. 3. Review: The insurance company reviews the request to determine if the treatment is medically necessary and covered by your plan. 4. Decision: The insurance company approves or denies the request. If approved, you can proceed with the treatment; if denied, you may need to explore other options or appeal the decision.
