How to Appeal a Cigna Denial in Connecticut

Step 1: Read and Document the Denial

Your denial letter must include the specific reason, plan provision or clinical criteria relied on, and your appeal rights with deadlines. Under ERISA Section 503 and ACA regulations, request the complete claims file — including reviewer notes and the specific Cigna MCP applied — if this information is not included.

Step 2: Gather Evidence and Identify Connecticut-Specific Protections

Collect medical records, physician letters, and clinical guidelines. Connecticut's mental health parity statute (Conn. Gen. Stat. § 38a-514b) requires health insurers to cover mental health and substance use disorders on the same basis as physical health conditions — supplementing federal MHPAEA. Connecticut's Managed Care Act (Conn. Gen. Stat. § 38a-478 et seq.) establishes specific requirements for timely access to care, grievance procedures, and utilization review standards. Connecticut has also enacted step therapy exception protections.

Step 3: Request a Peer-to-Peer Review

Your treating physician can call Cigna or eviCore to speak directly with the reviewing clinician. Because Cigna is headquartered in Connecticut, its clinical teams are often reachable and familiar with Connecticut regulatory expectations. Many denials are resolved at this stage.

Step 4: File Your Level 1 Internal Appeal

Submit within 180 days of the denial. Send via certified mail AND through myCigna.com. Include all documentation and cite relevant Connecticut statutes (Conn. Gen. Stat. § 38a-591a for external review, § 38a-514b for mental health parity, § 38a-478 for Managed Care Act) and federal protections.

Step 5: Escalate if Needed

File for external review with the Connecticut Insurance Department at portal.ct.gov/CID — (860) 297-3800. Connecticut's external review statute applies clinical standards of care and binds Cigna. As Cigna's home state regulator, the CID has both the authority and deep familiarity to act effectively. For high-value denials, consult an insurance appeal attorney in Connecticut.
