Cigna Behavioral Health Appeals in Washington
Appealing a Cigna behavioral health denial in Washington means tracking two separate clocks: Cigna's own 30-day Level-1 appeal window, and Washington's 30-day prompt-payment statute (WAC 284-170-431) for clean-claim payment. This guide covers both, plus Cigna's filing address and Washington's parity protections.

Washington's prompt-payment window
In Washington, state-regulated (fully-insured) plans — including many Cigna plans — generally must pay or formally respond to a clean claim within 30 calendar days under WAC 284-170-431. This deadline does not bind self-funded ERISA plans. This is a claim-payment deadline, not the appeal-decision deadline. If Cigna missed this window on your claim, cite it as a separate payment violation alongside your Cigna appeal — not as the deadline for the appeal decision itself.
Carriers must pay 95% of the monthly volume of clean claims within 30 days, and pay or deny 95% of all claims within 60 days, under WAC 284-170-431(2)(a). This is a claim-payment standard, not an appeal-decision deadline. Washington SB 5432 (2023) strengthened MHPAEA enforcement.
MHPAEA parity for Cigna in Washington
Washington adds state-level parity protection
Washington SB 5432 (2023) enacted some of the strongest state-level parity protections in the country, requiring health carriers to demonstrate NQTL equivalence, authorizing the Office of the Insurance Commissioner (OIC) to impose penalties for violations, and establishing a parity compliance review process. Washington enforcement of NQTL standards is active and independent of federal non-enforcement.
Statute: RCW 48.43.766; WA SB 5432 (2023)
Cigna's parity posture: Cigna is subject to federal MHPAEA parity requirements for its commercial/ERISA plans. Explicitly invoke 29 CFR § 2590.712 and request the Non-Quantitative Treatment Limitation comparative analysis in writing.
When appealing a Cigna denial in Washington on a state-regulated, fully-insured plan, cite both federal MHPAEA (29 CFR § 2590.712) and RCW 48.43.766; WA SB 5432 (2023) together — the state statute remains in force regardless of the 2025 federal non-enforcement of the 2024 MHPAEA Final Rule. Self-funded ERISA plans are preempted from state insurance law, so rely on federal MHPAEA alone there.
Common Cigna denial codes
Washington's insurance commissioner
If your internal Cigna appeal is denied, Washington'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 Cigna plan is employer-sponsored and self-funded, your remedies run through the U.S. Department of Labor (EBSA) rather than Washington's commissioner.

How long does Cigna have to respond to an appeal in Washington?
Cigna generally has 30 calendar days to respond to a Level-1 appeal. Separately, Washington's prompt-payment statute gives payers 30 days to respond to a clean claim (WAC 284-170-431) — a different deadline governing claim payment, not the appeal decision.
Does MHPAEA apply to Cigna in Washington?
Generally, yes — for Cigna's group health plans. Federal MHPAEA applies to Cigna's group health plans in Washington. RCW 48.43.766; WA SB 5432 (2023) additionally applies for state-regulated, fully-insured plans — self-funded ERISA plans are preempted from state insurance law and rely on federal MHPAEA alone; where it applies, Washington's state law remains in force regardless of the 2025 federal non-enforcement announcement.
