Bevacizumab (Avastin) prior authorization at Regence
Submission criteria, P2P prep, and appeal path if denied — for prescribers and PA staff
Regence requires prior-authorization documentation for Bevacizumab (Avastin): a diagnosis with ICD-10 code, documented step-therapy history, and prescriber attestation of medical necessity. Standard PA decisions return on the clock printed in the current member-specific payer source; if denied, use the appeal window printed on the denial notice to appeal.
The PA criteria you'll need to meet
Regence reviews Bevacizumab (Avastin) prior authorizations against its medical policy . Regence-specific context: BCBS licensee operating in Oregon, Washington (Clark/Cowlitz counties), Idaho, and Utah (~3.1M members). Subsidiary of Cambia Health Solutions. Prime Therapeutics PBM. Each state's DOI handles complaints for policies issued in that state.
Documentation packet checklist
- Chart note with diagnosis (ICD-10 code) and clinical severity markers
- Documented failure of, contraindication to, or intolerance of step-therapy alternatives in this class
- Prior treatment history including dosing, duration, and reason for discontinuation
- Relevant labs, imaging, or assessment scores supporting medical necessity
- Prescriber attestation linking the FDA-approved indication to the patient's presentation
- Regence's medical policy URL referenced in the cover letter
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:
- Cross-state coordination for multi-state members (OR/WA/ID/UT)
- Step therapy via Prime Therapeutics
- Behavioral health network adequacy
- Specialty drug PA
Bevacizumab (Avastin)-specific review scenarios and context
Check whether the current notice cites any of these label-, REMS-, or policy-related scenarios:
- Off-label use (ovarian, cervical maintenance)
- Plan-mandated biosimilar switch
- Site-of-care reduction
- Compounded intravitreal use denial (Avastin off-label for AMD)
Brand: Avastin. VEGF inhibitor. Biosimilars: Mvasi, Zirabev, Alymsys, Vegzelma, Avzivi. Off-label intravitreal use for wet AMD is widespread but commonly denied — appeals lean on AAO clinical practice and CATT trial.
Manufacturer patient-assistance program: Genentech Patient Foundation — relevant when a Regence denial sticks and the patient needs bridge access while appealing.
How Regence approaches Biosimilars PAs
For Bevacizumab, check whether the current Regence Biosimilars policy cites step therapy via prime therapeutics or specialty drug pa. Pharmacy-benefit review for Bevacizumab at Regence is routed through Prime Therapeutics. 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 Regence; if denied, use the filing date and route printed on that denial notice. Regence treats interchangeability designation and prescriber "dispense-as-written" language as the two pivot points for biosimilar-vs-reference disputes. Regence is domiciled in OR, so unresolved appeals escalate to the OR 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://www.regence.com/provider) with the same packet plus an applicable, current clinical source supporting Bevacizumab (Avastin)for the patient's indication.

Frequently asked questions
What documentation does Regence need for Bevacizumab (Avastin) prior auth?
Regence's typical PA packet for Bevacizumab (Avastin): (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.
What's the turnaround time at Regence?
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 Bevacizumab (Avastin) at Regence?
Preparation scenarios to check against the current notice and policy include: Cross-state coordination for multi-state members (OR/WA/ID/UT); Step therapy via Prime Therapeutics; Behavioral health network adequacy. These are not measured frequency claims. For Bevacizumab (Avastin), verify whether the actual denial raises step therapy, indication, or another plan-specific criterion before responding.
Can Regence force a mid-treatment switch from the reference biologic to Bevacizumab?
Regence 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 Prime Therapeutics. External-review escalation for Regence fully-insured policies sits with the OR insurance department.
How do I prep for a peer-to-peer with Regence on Bevacizumab (Avastin)?
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.
