Why they said no
Common reasons CT Scan claims are denied
Not medically necessary based on clinical criteria
MRI recommended instead of CT
Prior imaging not attempted first
Aetna checks
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
What works
How to Strengthen Your CT Scan Appeal
Physician order with clinical indication
Evidence that CT is more appropriate than MRI for the condition
ACR Appropriateness Criteria supporting CT for diagnosis
Rules to verify
Rights and coverage rules that may apply
The plan’s CT imaging and medical-necessity criteria — most diagnostic CT scans are not ACA preventive services
Preventive-service rules — apply only when the exact screening and patient criteria meet a current covered recommendation
Emergency prudent-layperson rules — relevant only when the scan is part of an emergency claim governed by those protections

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
