Denial scenarios to check against the current policy
These are preparation scenarios, not frequency claims. Use only those supported by the current member-specific source:
- Mental health parity violations
- Step therapy
- Specialty drug prior auth
- OON balance billing disputes
TRASTUZUMAB (Herceptin)-specific review scenarios and context
Check whether the current notice cites any of these label-, REMS-, or policy-related scenarios:
- Plan-mandated biosimilar switch mid-treatment
- HER2 IHC 2+ with FISH equivocal — plan demands IHC 3+
- Adjuvant duration beyond 1 year
- Site-of-care reduction
Brand: Herceptin. Reference biologic for HER2-positive breast and gastric cancer. Biosimilars: Kanjinti, Trazimera, Ogivri, Ontruzant, Herzuma. Also a component of Enhertu (trastuzumab deruxtecan, separate molecule) and Kadcyla.
Manufacturer patient-assistance program: Genentech Patient Foundation — relevant when a Cigna denial sticks and the patient needs bridge access while appealing.
How Cigna approaches Biosimilars PAs
For TRASTUZUMAB (ONTRUZANT), check whether the current Cigna Biosimilars policy cites step therapy or specialty drug prior auth. Pharmacy-benefit review for TRASTUZUMAB (ONTRUZANT) at Cigna is routed through Express Scripts (in-house since the 2018 acquisition). 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 Cigna; if denied, use the filing date and route printed on that denial notice. Cigna treats interchangeability designation and prescriber "dispense-as-written" language as the two pivot points for biosimilar-vs-reference disputes. Cigna 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).
If the PA is denied
Verify the appeal window and decision clock in the current denial notice and member-specific payer source before relying on either. Submit through the provider portal (https://cignaforhcp.cigna.com) with the same packet plus an applicable, current clinical source supporting TRASTUZUMAB (Herceptin)for the patient's indication.

Frequently asked questions
What documentation does Cigna need for TRASTUZUMAB (Herceptin) prior auth?
Cigna's typical PA packet for TRASTUZUMAB (Herceptin): (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 HER2/neu Receptor Antagonist, expect clinical-criteria documentation specific to this class.
What's the turnaround time at Cigna?
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 TRASTUZUMAB (Herceptin) at Cigna?
Preparation scenarios to check against the current notice and policy include: Mental health parity violations; Step therapy; Specialty drug prior auth. These are not measured frequency claims. For TRASTUZUMAB (Herceptin), verify whether the actual denial raises step therapy, indication, or another plan-specific criterion before responding.
Can Cigna force a mid-treatment switch from the reference biologic to TRASTUZUMAB (ONTRUZANT)?
Cigna can require biosimilar use at initiation, but mid-treatment forced switches face higher appeal-reversal rates when the chart documents a stable patient, a defined transition-of-care concern, or prescriber "dispense-as-written" intent supported by a clinical rationale (immunogenicity history, nocebo response in prior switches, narrow therapeutic window). Cite the FDA Purple Book interchangeability designation when arguing the switch — interchangeable biosimilars permit pharmacy substitution; non-interchangeable biosimilars do not. Pharmacy-benefit handling is routed through Express Scripts (in-house since the 2018 acquisition). External-review escalation for Cigna fully-insured policies sits with the CT insurance department.
How do I prep for a peer-to-peer with Cigna on TRASTUZUMAB (Herceptin)?
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.
