How Aetna approaches GLP-1 receptor agonists PAs
For TIRZEPATIDE (ZEPBOUND), check whether the current Aetna GLP-1 receptor agonists policy cites step therapy on specialty drugs. Pharmacy-benefit review for TIRZEPATIDE (ZEPBOUND) at Aetna is routed through CVS Caremark (parent CVS Health since 2018). The applicable review clock depends on the member's current product, whether the request is complete and urgent, and governing plan rules. Confirm receipt and timing with Aetna; if denied, use the filing date and route printed on that denial notice. The current Aetna policy may distinguish T2D-indication PAs (Ozempic, Mounjaro, Trulicity) from weight-management-indication PAs (Wegovy, Zepbound, Saxenda); verify any benefit-exclusion language in the member product. Aetna is domiciled in CT, so unresolved appeals escalate to the CT insurance department's external-review program for fully-insured policies (self-funded ERISA plans route to the DOL EBSA instead).

Frequently asked questions
What documentation does Aetna need for TIRZEPATIDE (Mounjaro, Zepbound) prior auth?
Aetna's typical PA packet for TIRZEPATIDE (Mounjaro, Zepbound): (1) chart note documenting the indication and prior-treatment failures, (2) supporting lab/imaging where indicated, (3) prescriber attestation that step-therapy alternatives were tried or contraindicated, (4) FDA-approved indication mapped to ICD-10 diagnosis. For Glucose-dependent Insulinotropic Polypeptide Receptor Agonist, expect clinical-criteria documentation specific to this class.
What's the turnaround time at Aetna?
Verify the decision clock in the current member-specific payer policy and request receipt. Product type, urgency, state law, and plan terms can change the applicable timing; this page does not supply an operational deadline.
What documentation issues should be checked for TIRZEPATIDE (Mounjaro, Zepbound) at Aetna?
Preparation scenarios to check against the current notice and policy include: UM-2575 medical necessity denials; Prior auth absent; Step therapy on specialty drugs. These are not measured frequency claims. For TIRZEPATIDE (Mounjaro, Zepbound), verify whether the actual denial raises step therapy, indication, or another plan-specific criterion before responding.
Why does Aetna require specific BMI documentation for TIRZEPATIDE (ZEPBOUND)?
Aetna's GLP-1 prior-auth policy distinguishes T2D-indication submissions (A1C-based criteria) from weight-management-indication submissions (BMI ≥30, or ≥27 with weight-related comorbidity, matching the FDA label). For weight-management TIRZEPATIDE (ZEPBOUND) the reviewer also screens for the plan's anti-obesity-medication exclusion — submit the chart note with BMI, weight-related comorbidity (HTN, dyslipidemia, T2D, OSA, OA), and either (a) documented lifestyle intervention or (b) a documented reason intensive lifestyle was inappropriate. Verify current criteria and timing in the member-specific payer source. Pharmacy-benefit handling is routed through CVS Caremark (parent CVS Health since 2018). External-review escalation for Aetna fully-insured policies sits with the CT insurance department.
How do I prep for a peer-to-peer with Aetna on TIRZEPATIDE (Mounjaro, Zepbound)?
Lead with the FDA-approved indication and the specific clinical criteria the policy lists. Have the patient's chart open, document number, and policy URL on screen. State your name and credentials, the policy number, the indication, and the documented failures of step-therapy alternatives. Keep notes — if the P2P reviewer overturns, get the decision in writing.
