Before You Start: Verify Your Coverage

Check Your Plan Type

Lutathera is covered under Aetna's medical benefit, not as a retail prescription. This means:

  • It's administered in a hospital or specialty infusion center
  • Billed using HCPCS code A9513 (per mCi)
  • Subject to medical benefit deductibles and coinsurance

Confirm Network Status

Ensure your treating facility and nuclear medicine team are in-network with your Aetna plan. Out-of-network administration can significantly increase costs and complicate prior authorization.

Verify Specialty Pharmacy Requirements

While Lutathera isn't dispensed through retail pharmacy, coordinate with CVS Specialty or your plan's designated specialty pharmacy for any required coordination of benefits.

From Our Advocates: We've seen several successful Lutathera appeals in Michigan where the initial denial cited "experimental" status.

Most external reviews through DIFS ruled in favor of coverage when the clinical evidence clearly supported medical necessity.
