What “Not Medically Necessary” Actually Means
If your imaging, therapy, or procedure was denied by Aetna as “not medically necessary,” it usually means the insurance company doesn’t believe there was enough clinical evidence to justify the service.
These decisions are often based on documentation—not your actual condition or symptoms. If key details are missing, your claim may be denied even if the service was appropriate.
Why Aetna Claims Get Denied
Claims are often denied for reasons like:
- The service wasn’t considered necessary based on symptoms
- Missing or incomplete provider documentation
- The diagnosis didn’t meet the insurer’s criteria
- Prior treatments weren’t documented (when required)
Even a recommended service can be denied if it isn’t properly documented.
What Aetna Is Really Looking For
Insurance companies want to see:
- Clear clinical reasoning for why the service was needed
- Documentation supporting your condition or symptoms
- Provider notes explaining medical necessity
- Evidence that the request aligns with their guidelines
If your appeal doesn’t include this, it may be denied again.
Common Mistakes When Appealing a Denial
Common mistakes include:
- Submitting the same documentation without addressing the denial reason
- Not including provider notes that justify the service
- Failing to explain why the service was necessary
- Sending incomplete or disorganized records
Appeals need to show new, stronger justification.
Before You Submit Your Appeal
Before you submit your appeal, make sure you’re not missing something that could lead to another denial.
Many appeals fail because missing details are not obvious until after submission. Use the checklist before you send anything.
