Cigna Denied Your Claim in Tennessee? How to Fight Back

Cigna (Evernorth) operates across all major plan types in Tennessee through employer-sponsored, ACA marketplace, and Medicare Advantage plans. Claim denials follow predictable patterns — and with the right strategy, they can be overturned. Both federal law and Tennessee state law protect your right to challenge a denial, and Tennessee has a state-administered IRO program under Tenn. Code Ann. § 56-32-230 to back you up.

Why Insurers Deny Claims in Tennessee

Cigna's most common denial reasons in Tennessee include:

• Not medically necessary — Cigna's reviewer determined the treatment does not meet its clinical policy criteria or eviCore standards
• Prior Authorization Denied: How to Appeal" class="auto-link">Prior authorization not obtained — The service required pre-approval that was not secured before treatment
• Out-of-network provider — The provider is not in Cigna's Tennessee network
• Service not covered — The specific treatment is excluded from your plan
• Step therapy required — Cigna requires a less expensive option first
• Insufficient documentation — Clinical records submitted do not support the claim
• Filing deadline missed — Claim submitted after Cigna's filing window

Each denial reason requires a different appeal strategy. Start by identifying the exact language on your denial letter.

How to Appeal a Cigna Denial in Tennessee

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 ERISA Section 503 and ACA regulations, request the complete claims file — including reviewer notes and the specific MCP Cigna used. Tennessee law (Tenn. Code Ann. § 56-32-230) requires Cigna to decide internal appeals within 30 days for non-urgent claims and 72 hours for urgent/expedited requests.

Step 2: Gather Evidence and Identify Tennessee-Specific Protections

Collect medical records, physician letters, and clinical guidelines. Your physician's letter of medical necessity should cite the applicable clinical guidelines and directly address Cigna's stated denial reason. Tennessee enforces Mental Health Parity Act (MHPAEA) Explained" class="auto-link">MHPAEA — if Cigna applied stricter criteria to mental health or substance use claims than to comparable medical claims, file a parity complaint with the TDCI simultaneously. Tennessee's prompt pay statute (Tenn. Code Ann. § 56-7-109) requires commercial insurers to pay clean claims within 30 days (electronic) or 45 days (paper).

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 director. This often resolves denials faster than formal written appeals. Request peer-to-peer review before or alongside your written appeal.

Step 4: File Your Level 1 Internal Appeal

Submit within 180 days of the denial. Send via certified mail AND through the myCigna.com member portal. Reference your member ID, claim number, date of service, and denial date. Cite Tenn. Code Ann. § 56-32-230 and applicable federal law in your appeal letter. Request reversal and set a response deadline.

Step 5: Escalate if Needed

If Cigna upholds the denial, request External Independent Review: Complete Guide" class="auto-link">external review through the Tennessee Department of Commerce and Insurance (TDCI) at tn.gov/commerce/insurance.html — (615) 741-2176 or (800) 342-4029. The IRO's decision is binding on Cigna. File a TDCI complaint simultaneously. For significant claims, consult an insurance appeal attorney familiar with Tennessee insurance law.
