How to appeal an Aetna maternity & postpartum denial

The framework that applies to your appeal

Federal law gives you the right to a full and fair internal appeal, then an external review by an independent third party.

Aetna-specific note: Owned by CVS Health since 2018. CVS Caremark is the PBM. Aetna ASA administers self-funded ERISA plans. Meritain Health is Aetna's TPA brand.

What Aetna's policy requires for maternity & postpartum

Cited policy: Aetna ACA §2713 Preventive Services — Breast Pump Coverage

ACA §2713 + HRSA mandate. Often interpreted to cover only basic manual model.

How Aetna denies maternity & postpartum — and how to counter it

Where Aetna pushes back: 1) Deluxe electric not medically necessary; 2) Hospital-grade rental denied.

Counter-arguments that hold up: ACA §2713 + HRSA Women's Preventive Services Guidelines mandate breastfeeding equipment + supplies without cost-sharing + WITHOUT restriction to lowest-cost device. CMS FAQ Part XXIX clarifies plans may NOT limit to manual pumps as default. Document medical-necessity scenario (return-to-work, NICU/preterm neonate, low milk supply, latch difficulty).

How to submit the appeal to Aetna

1. Read the denial letter — note the exact denial reason code and the appeal deadline (180 days from the date on the letter).
2. Gather supporting documentation: physician letter of medical necessity, relevant clinical notes, peer-reviewed citations supporting the treatment for your indication, and the policy or coverage document Aetna cited in the denial.
3. File the appeal through Aetna's portal (members: https://www.aetna.com ; providers: https://www.aetnaprovider.com). Standard decision returns within 30 days; expedited urgent appeals return within 72 hours.
4. If denied again, request external review by an independent reviewer within 4 months of the final internal denial. In CT, the state insurance department coordinates external review for fully-insured plans; ERISA self-funded plans use a federal external review through DOL/EBSA.
