Your Rights in Arizona

Arizona Department of Insurance and Financial Institutions

The Arizona Department of Insurance and Financial Institutions (DIFI) regulates insurance companies operating in Arizona, including Anthem's fully insured plans.

• Phone: (602) 364-3100
• Website: https://insurance.az.gov
• File a complaint: insurance.az.gov/file-complaint

You can file a formal complaint with the Arizona DIFI if Anthem is not following proper appeal procedures, failing to respond within required timeframes, or acting in bad faith.

Arizona-Specific Protections

Prompt-pay laws. Arizona has strong prompt-pay regulations requiring insurers to pay clean claims within 30 days for electronic submissions and 45 days for paper claims. If Anthem is delaying payment without a legitimate basis, this is a violation of Arizona's prompt-pay statute (A.R.S. § 20-3101 et seq.).

Direct access to specialists. Arizona law requires HMO plans to permit reasonable direct access to specialist care. If Anthem denied a specialist referral that your condition required, this may be a violation of Arizona's access-to-care requirements.

External review rights. Arizona has an independent external review process for fully insured plans. The IRO review is free and the decision is binding on Anthem.

ERISA plans. Most large employer group plans in Arizona are ERISA self-funded, meaning Arizona state mandates may not apply. However, ERISA and ACA protections remain in full force.

Federal Protections

• ACA — Essential health benefits, internal appeal rights, external review rights
• ERISA — For employer-sponsored plans: claims file access, full and fair review, federal court access
• Mental Health Parity Act (MHPAEA) Explained" class="auto-link">MHPAEA — Equal coverage for mental health and substance use treatment
• No Surprises Act — Protection from surprise bills for emergency and certain out-of-network services
