Why Insurers Deny Claims in Washington

• Not medically necessary — Cigna's reviewer determined treatment does not meet its clinical policy criteria or eviCore standards
• Prior Authorization Denied: How to Appeal" class="auto-link">Prior authorization not obtained — Service required pre-approval not secured before treatment

How to Appeal a Cigna Denial in Washington

Step 1: Read and Document the Denial

Your denial letter must include the specific reason, the policy provision relied on, and your appeal rights with deadlines. Under RCW 48.43.530 and federal ERISA Section 503, request the complete claims file — including reviewer notes and the specific criteria applied. You have 180 days from receipt of denial to file an internal appeal. Cigna must respond within 30 days for standard appeals, 72 hours for urgent requests, and 24 hours for emergent situations.

Step 2: Gather Evidence and Identify Washington-Specific Protections

Collect medical records, physician letters, and clinical guidelines. RCW 48.43.730 requires Cigna to grant step therapy overrides if the required drug has been tried and caused adverse effects or failed, is contraindicated, is not clinically appropriate, or if you are clinically stable on your current treatment. Washington law (RCW 48.43.093) requires Cigna to make prior authorization decisions within 72 hours for non-urgent requests and 24 hours for urgent requests — retroactive denial of previously authorized services is prohibited in most cases. Washington's Balance Billing Protection Act (RCW 48.49) is one of the strongest in the country.

Step 3: Request a Peer-to-Peer Review

For medical necessity denials, your treating physician can request a peer-to-peer review — a direct call with Cigna's medical reviewer. Washington law supports this right, and peer-to-peer review resolves a large percentage of clinical denials before formal escalation.

Step 4: File Your Level 1 Internal Appeal

Submit within 180 days. Send via certified mail AND through the myCigna member portal. Cite RCW 48.43.530 and applicable federal statutes in your appeal letter. Request reversal with a clear response deadline.

Step 5: Escalate if Needed

Request an IRO through the Washington Office of the Insurance Commissioner (OIC) at insurance.wa.gov — (800) 562-6900. The IRO's decision is binding on Cigna. File an OIC complaint simultaneously — Washington's OIC is highly responsive and actively investigates insurer violations. For step therapy overrides, cite RCW 48.43.730. For balance billing, cite RCW 48.49 and the No Surprises Act. For significant claims, consult a Washington insurance attorney.
