Why Insurers Deny Claims in Arizona
Cigna's most common denial reasons in Arizona include:
- Not medically necessary — Cigna's reviewer determined the treatment does not meet its Medical Coverage Policy (MCP) or eviCore clinical criteria
- 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 Arizona network
- Service not covered — The treatment is excluded from your plan
- Step therapy required — Cigna requires a less expensive alternative before approving the prescribed treatment

How to Appeal a Cigna Denial in Arizona
Step 1: Read and Document the Denial
Your denial letter must include the specific reason, the 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 to your case — if not already provided.
Step 2: Gather Evidence and Address the Specific Denial Reason
Collect medical records, physician letters, and clinical guidelines. Your physician's letter of medical necessity should address the denial reason using the specific language and criteria from Cigna's MCP, not general medical necessity language. Arizona's prompt-pay law (A.R.S. § 20-3101 et seq.) requires Cigna to pay or deny clean claims within 30 days for electronic and 45 days for paper claims — document any payment delays carefully.

Step 3: Request a Peer-to-Peer Review
Your treating physician can call Cigna or eviCore to speak directly with the reviewing clinician. This works especially well for prior authorization denials where clinical context makes a difference. Many Arizona 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 a cover letter that directly rebuts the denial reason with evidence and citations to Arizona law (A.R.S. § 20-3101, A.R.S. § 20-2533) and federal protections (ACA, ERISA, Mental Health Parity Act (MHPAEA) Explained" class="auto-link">MHPAEA, No Surprises Act).
Step 5: Escalate if Needed
Request independent review through the Arizona Department of Insurance and Financial Institutions (DIFI) at insurance.az.gov — (602) 364-3100. The IRO's decision is binding on Cigna. File a formal complaint with the Arizona DIFI simultaneously to create regulatory pressure. For high-value denials, consult an insurance appeal attorney in Arizona.
