About Sarah Chen, RN-BSN, CPC

Editorial lead and clinical reviewer at InsureDefense.

Background

Sarah Chen, RN-BSN, CPC, leads InsureDefense’s clinical review. She spent twelve years working appeals at a major US health insurer — first on the prior-authorization line, then as a senior appeals analyst, and finally on the medical-policy team that wrote the criteria reviewers applied to denials. She left the payer side in 2022 to work as an independent patient advocate, and joined InsureDefense as editorial lead in 2026.

Credentials

• Registered Nurse (RN-BSN). Bachelor of Science in Nursing. Licensed and active. Twelve years clinical-adjacent payer experience.
• Certified Professional Coder (CPC). American Academy of Professional Coders. CPT, HCPCS, and ICD-10 proficiency — the codes that drive most insurance denials.
• Four years as an independent patient advocate working medical-necessity and specialty-drug appeals for consumers.

Why this matters for your appeal

The reviewer who decides whether your appeal succeeds at the insurer almost certainly has a clinical background and works from a written set of criteria. The strongest appeals are written by someone who has seen those criteria from the inside. That’s why every Premium and Urgent appeal we prepare is reviewed by a named clinical specialist before delivery, not by an anonymous algorithm.

Editorial standards

Every guide on this site is reviewed by Sarah for factual accuracy and currency. Statistics come from Kaiser Family Foundation, the Centers for Medicare & Medicaid Services (CMS), HealthCare.gov, and state insurance department resources. Where a guide references an Anthem, Aetna, Cigna, UnitedHealthcare, BCBS, or Kaiser policy, the policy is named and dated. InsureDefense does not publish “our win rate” until we have audited outcome data from at least 100 closed cases.

What Sarah does not do

Sarah is not your physician, not your lawyer, and not a licensed insurance agent for the public. The reviewed appeals are document-preparation products, not medical or legal advice. For urgent medical situations, contact your doctor or emergency services directly. For complex legal disputes — ERISA litigation, alleged bad faith, large damages — consult a healthcare attorney.
