Aetna Behavioral Health Appeals in Ohio

Appealing an Aetna behavioral health denial in Ohio means tracking two separate clocks: Aetna's own 30-day Level-1 appeal window, and Ohio's 30-day prompt-payment statute (Ohio Rev. Code § 3923.13) for clean-claim payment (best-effort default — verify). This guide covers both, plus Aetna's filing address and Ohio's parity protections.

Ohio's prompt-payment window

This data is a best-effort default based on a general survey of state insurance codes. Verify the current statute and day count with Ohio's Department of Insurance before citing it in an appeal.

In Ohio, state-regulated (fully-insured) plans — including many Aetna plans — generally must pay or formally respond to a clean claim within 30 calendar days under Ohio Rev. Code § 3923.13. This deadline does not bind self-funded ERISA plans. This is a claim-payment deadline, not the appeal-decision deadline. If Aetna missed this window on your claim, cite it as a separate payment violation alongside your Aetna appeal — not as the deadline for the appeal decision itself.

MHPAEA parity for Aetna in Ohio

Federal MHPAEA (29 USC § 1185a; 29 CFR § 2590.712) applies to Aetna's group health plans operating in Ohio. The CAA 2021 § 203 disclosure duty requires Aetna to produce its NQTL comparative analysis on request.

Aetna's parity posture: Aetna publishes MHPAEA comparative analyses on request; behavioral health benefits are administered through Aetna Behavioral Health. Document parity violation in detail — Aetna's internal process requires a specific MHPAEA flag in the appeal routing system.

State-level parity laws may add further protections in Ohio — check with the state's Department of Insurance for current guidance.

Common Aetna denial codes

The most common Aetna denial codes for behavioral health are: CO-4, CO-97, CO-50, CO-45. Each has a dedicated guide with the denial explanation and appeal strategy.

Ohio's insurance commissioner

If your internal Aetna appeal is denied, Ohio's Department of Insurance can help with a complaint or external review for fully-insured plans. Look up the official contact via the NAIC consumer locator.

Note: self-funded ERISA plans are generally exempt from state insurance regulation. If your patient's Aetna plan is employer-sponsored and self-funded, your remedies run through the U.S. Department of Labor (EBSA) rather than Ohio's commissioner.
