Out-of-network oncologist required for specialized care

Issues to check in the Aetna notice
A "not medically necessary" finding — ask which records the reviewer actually had and which written criteria were applied
Step-therapy requirements — check whether the plan credited treatments you already tried and documented
For Medicare Advantage, criteria that may differ from applicable Medicare rules — compare the cited policy with the current NCD, LCD, or permitted public internal criteria

Tips for Appealing to Aetna
Request the specific clinical criteria used to deny your claim
Ask for a peer-to-peer review between your doctor and their medical director
If the internal appeal fails, external review or a regulator complaint may be an option — a state-regulated plan goes to your state insurance department; a self-funded employer (ERISA) plan is overseen by the U.S. Department of Labor (EBSA), not the state
