How to Appeal a Cigna Denial in Wisconsin

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 Wis. Stat. § 632.83 et seq. and federal ERISA Section 503, request the complete claims file — including reviewer notes and the specific clinical criteria applied. You have 180 days from receipt of denial to file an internal appeal. Cigna must respond within 30 days for standard appeals and 72 hours for urgent/expedited requests.

Wisconsin has enacted step therapy override requirements for prescription drugs.

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. This is often the fastest path to overturning a clinical denial before formal appeal.

Step 4: File Your Level 1 Internal Appeal

Step 5: Escalate if Needed

Request an IRO through Wisconsin OCI at oci.wi.gov — (608) 266-3585 or (800) 236-8517. The IRO's decision is binding on Cigna. File an OCI complaint simultaneously. For step therapy overrides, document prior drug failures or contraindications and request an override under Wisconsin's step therapy statute. For prompt-pay violations, file a separate OCI complaint under Wis. Stat. § 628.46. For significant claims, consult a Wisconsin insurance attorney. ERISA plan members may file suit in federal court under 29 U.S.C. § 1132.

What to Include in Your Appeal

• Cigna denial letter with the specific denial code and reason
• Complete medical records related to the denied service
