Aetna MRI and imaging appeal

Why Aetna (CVS Health) denies mri and imaging

Aetna, owned by CVS Health since 2018, runs commercial group plans, Medicare Advantage, and a large pharmacy benefit footprint via Caremark. GLP-1, specialty drug, and behavioral health denials are the highest-volume categories.

For mri and imaging specifically: MRI, CT, PET, and other imaging denials are almost always issued at the prior-auth stage. They move fast, and so should the appeal.

The law that controls this appeal

The ACR Appropriateness Criteria are the recognized clinical standard; the plan's radiology-benefit-manager criteria must be disclosed on request.

What Aetna (CVS Health) denies for mri and imaging

The mri and imaging services most often denied:

Cardiac imaging (echo, MUGA, stress)
Repeat imaging within 90 days

Why mri and imaging claims get denied

A typical Aetna (CVS Health) mri and imaging denial almost always cites one of these reasons. Each one maps to a specific rebuttal in the appeal:

Conservative imaging (X-ray, ultrasound) not tried first
Documented symptoms don't match imaging request
Out-of-network imaging facility
Plan claims it's a 'screening,' not diagnostic
ICD coding doesn't justify the CPT requested

Common Aetna (CVS Health) denial patterns for mri and imaging

GLP-1 / Wegovy denials citing BMI. Aetna denies most weight-loss GLP-1 prescriptions citing BMI thresholds or 'lifestyle modification first' criteria. Switching the prescription path to a T2D-approved molecule (Ozempic, Mounjaro) when comorbidities exist often produces a same-week reversal.
Caremark formulary denials. Aetna's pharmacy benefit (Caremark) issues formulary denials separate from medical benefit denials. Each requires its own appeal track, confusing the two costs weeks.
Internal appeal then external review. Aetna's first appeal is internal and must be filed within 180 days. After internal denial, an external review by an Independent Review Organization (IRO) is available within 60 days, a separately strong reversal lane.

How to win your Aetna (CVS Health) mri and imaging appeal

Strategy for mri and imaging: Mark the appeal as urgent, most plans honor this when the ordering physician signs off. Request peer-to-peer the same day. Provide symptom documentation that maps directly to the imaging-justification ICD codes.

Filed against Aetna (CVS Health), that strategy rides on this procedural spine:

Procedural-rights anchor. Every Aetna (CVS Health) denial triggers ERISA § 503 or 45 C.F.R. § 147.136 procedural rights. The cover letter invokes these in the opening paragraph to lock the timeline and force criteria disclosure.
Criteria-disclosure demand. Aetna (CVS Health) frequently denies on "not medically necessary" without disclosing the clinical criteria applied. Once disclosed, those criteria become the rebuttal map.
Controlling-standard citation. The ACR Appropriateness Criteria are the recognized clinical standard; the plan's radiology-benefit-manager criteria must be disclosed on request.
Treating-provider attestation. A letter from the treating physician addressing each criterion in Aetna (CVS Health)'s own policy language. This is the single strongest evidentiary element.
Requested action. A specific demand to reverse the mri and imaging denial and approve the service, not a general "please reconsider."

Aetna (CVS Health) mri and imaging appeals: frequently asked questions

Can I appeal your Aetna (CVS Health) MRI or imaging denial?

Yes, and quickly. Imaging denials are almost always issued at prior authorization. Mark the appeal urgent if your ordering physician signs off, which compresses the decision to 72 hours, and request a same-day peer-to-peer review.

How long does your Aetna (CVS Health) imaging appeal take?

An urgent designation requires a decision within 72 hours; standard appeals take up to 30 days. Most plans allow 180 days to file the appeal itself.

Why was my MRI denied as not necessary?

Common reasons are that conservative imaging such as X-ray or ultrasound was not tried first, the symptoms do not match the imaging request, or the ICD diagnosis codes do not justify the CPT ordered. The ACR Appropriateness Criteria are the recognized standard to cite back.

What proves an MRI is medically necessary?

Symptom documentation that maps directly to the imaging-justification diagnosis codes, the ordering physician's notes, and any prior imaging. Citing the ACR Appropriateness Criteria for your clinical scenario is decisive.
