Understanding Regence BlueCross BlueShield

Regence operates through state-specific entities:

• Regence BlueShield (Washington)
• Regence BlueCross BlueShield of Oregon (Oregon)
• Regence BlueCross BlueShield of Utah (Utah)
• Regence BlueShield of Idaho (Idaho)

Each entity is licensed by its respective state insurance department. Regence is part of the Cambia Health Solutions family of companies, which also includes other health and wellness brands in the Pacific Northwest.

Common Reasons Regence Denies Claims

• Prior Authorization Denied: How to Appeal" class="auto-link">Prior authorization: Regence requires advance approval for many procedures, specialty medications, surgeries, imaging studies, and inpatient admissions.
• Medical necessity: Regence uses clinical criteria to evaluate whether a service is medically necessary. These reviews may not always align with your treating physician's clinical judgment.
• Out-of-network care: Regence HMO plans restrict coverage to network providers. PPO members may have out-of-network benefits but face higher cost-sharing.
• Formulary restrictions: Specialty drugs and non-preferred brand medications may be denied or require step therapy.
• Coding and billing errors: Incorrect procedure or diagnosis codes from your provider can result in automatic denials.

How to File a Regence Appeal

1. Obtain your denial notice: Regence must provide a written denial with the specific reason, the clinical criteria applied, and your appeal rights. Review this document carefully.

2. Contact Regence Member Services: Call 888-367-3424 or the number on your insurance card. Ask for the appeals and grievances department and request written appeal instructions.

3. Submit your written appeal: Mail to Regence BlueCross BlueShield (or the appropriate state entity), Attn: Grievances and Appeals, P.O. Box 1827, Medford, OR 97501. Alternatively, use the address specified in your denial letter, as processing centers may vary by state.

4. Gather medical evidence: Obtain a letter of medical necessity from your treating physician that specifically addresses the denial criteria Regence cited. Include clinical records, test results, and published medical guidelines.

5. Request a peer-to-peer review: Your physician can request a direct clinical discussion with Regence's medical director. This step often resolves medical necessity disputes before a formal appeal decision.

6. Escalate to your state regulator: File a complaint with the WA OIC, Oregon Insurance Division, Idaho DOI, or Utah Insurance Department if Regence is unresponsive or the denial appears improper.

Federal Employee Program (FEP) Members

Regence administers Federal Employee Program (FEP) plans for federal employees in its service territory. FEP members have appeal rights through the Office of Personnel Management (OPM) in addition to Regence's internal process. Contact Regence FEP at the number on your card and, if needed, escalate to OPM at opm.gov/healthcare-insurance.

Multi-State Considerations

If you receive care in one Regence state while living in another (for example, a Washington resident treated in Oregon), clarify which state's plan document and which state's appeal procedures apply. Generally, the state where your plan was issued governs your appeal rights. Contact Regence's member services to confirm.

Oregon Surprise Billing and Balanced Billing Protections

Oregon has specific surprise billing protections that apply to Regence members receiving care at out-of-network facilities or from out-of-network providers during otherwise covered procedures. If your denial or unexpected bill involves a provider you did not knowingly choose as out-of-network, Oregon's protections may apply.

Mental Health Parity Across Regence States

All four states where Regence operates have mental health parity laws, in addition to the federal Mental Health Parity and Addiction Equity Act (MHPAEA). If your denial involves behavioral health, mental health, or substance use disorder treatment, compare Regence's coverage standards to how it handles comparable medical/surgical benefits. Apparent parity violations are legally significant grounds for appeal.
