How to appeal your Aetna (CVS Health) medicare denial
Medicare denials follow a federally-defined 5-level appeal process. This guide is specific to Aetna (CVS Health) appeals.
Why Aetna (CVS Health) denies medicare
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 medicare specifically: Medicare denials follow a federally-defined 5-level appeal process. Most beneficiaries stop at level 1. The higher levels, particularly the Independent Review Entity and ALJ, reverse a meaningful share of cases.
Coverage must track Traditional Medicare (NCDs and LCDs); CMS rule CMS-4201-F (2024) bars algorithm-only denials, resolved through the federal five-level appeal ladder.
What Aetna (CVS Health) denies for medicare
The medicare services most often denied:
- Skilled nursing facility (SNF) coverage
- Home health services
- Durable medical equipment (hospital beds, oxygen, mobility)
- Hospice eligibility
- Inpatient vs. observation status
- Part D drug coverage (separate ladder)
Why medicare claims get denied
A typical Aetna (CVS Health) medicare denial almost always cites one of these reasons. Each one maps to a specific rebuttal in the appeal:
- Plan claims criteria for SNF / home-health not met
- DME deemed 'not medically necessary' or 'convenience'
- Inpatient stay reclassified as observation (lower coverage)
- Drug not on plan formulary or step therapy required
The Aetna (CVS Health) appeal process
Appeal levels: Internal level 1 (30 days standard / 72h urgent), then external IRO review (45 days standard).
Carrier timing: 180 days from denial for internal appeal; 60 days from final internal denial for external review.
Medicare timing: 60 days between each appeal level. Level-3 ALJ requires the case value to exceed $200 (2026), multiple denials can be consolidated to meet this threshold.
What we know about Aetna (CVS Health): Aetna's internal appeals respond well to peer-to-peer review requests filed alongside the written appeal.
Common Aetna (CVS Health) denial patterns for medicare
- 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) medicare appeal
Strategy for medicare: File at level 1 within 60 days. Begin level-2 paperwork immediately on receipt of level-1 denial. The ALJ level (level 3) is where the most complex reversals happen, Medicare provides a federal judge to hear the case by phone.
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. Coverage must track Traditional Medicare (NCDs and LCDs); CMS rule CMS-4201-F (2024) bars algorithm-only denials, resolved through the federal five-level appeal ladder.
- 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 medicare denial and approve the service, not a general "please reconsider."
Documents you'll need for your Aetna (CVS Health) medicare appeal

What a medicare appeal can recover
Typical recovery for medicare cases runs $1,000 - $100,000+. The exact figure depends on the specific service and your plan's contracted rates.
Aetna (CVS Health) medicare appeals: frequently asked questions
How do I appeal your Aetna (CVS Health) Medicare denial?
Medicare denials follow a federal five-level appeal process. File level 1 within 60 days, and begin level-2 paperwork the moment the level-1 denial arrives. The Independent Review Entity and the ALJ levels reverse a meaningful share of cases.
What is the deadline for each Medicare appeal level?
You generally have 60 days between each level. The level-3 ALJ hearing requires the case value to exceed roughly $200, and multiple denials can be consolidated to meet that threshold.
Why was my SNF, home health, or DME denied?
Plans deny when they claim the skilled-nursing or home-health criteria are not met, when equipment is deemed convenience rather than medically necessary, or when an inpatient stay is reclassified as observation. Coverage must track Traditional Medicare's national and local coverage determinations.
Does an algorithm decide Aetna (CVS Health) Medicare Advantage denials?
It cannot be the sole basis. CMS rule CMS-4201-F (2024) prohibits algorithm-only coverage denials in Medicare Advantage; a denial that relies on a data model instead of your individual record is non-compliant and appealable on that ground.
