Anthem (BCBS) Behavioral Health Appeals in Washington
Appealing an Anthem (BCBS) behavioral health denial in Washington means tracking two separate clocks: Anthem (BCBS)'s own 30-day Level-1 appeal window, and Washington's 60-day prompt-payment statute (RCW 48.43.005) for clean-claim payment. This guide covers both, plus Anthem (BCBS)'s filing address and Washington's parity protections.

Washington's prompt-payment window
In Washington, state-regulated (fully-insured) plans — including many Anthem (BCBS) plans — generally must pay or formally respond to a clean claim within 60 calendar days under RCW 48.43.005. This deadline does not bind self-funded ERISA plans. This is a claim-payment deadline, not the appeal-decision deadline. If Anthem (BCBS) missed this window on your claim, cite it as a separate payment violation alongside your Anthem (BCBS) appeal — not as the deadline for the appeal decision itself.
Clean-claim payment window: 30 days EFT / 60 days paper under RCW 48.43.005. This is a claim-payment deadline, not an appeal-decision deadline. Washington SB 5432 (2023) strengthened MHPAEA enforcement.
MHPAEA parity for Anthem (BCBS) 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)
Anthem (BCBS)'s parity posture: Anthem (now Elevance Health) is a major BCBS licensee operating in ~14 states. File appeals to the state-specific Anthem entity; addresses vary by state. Behavioral health managed through Sydney Health / Anthem Behavioral Health.
When appealing an Anthem (BCBS) 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 Anthem (BCBS) denial codes
Washington's insurance commissioner
If your internal Anthem (BCBS) 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 Anthem (BCBS) 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 Anthem (BCBS) have to respond to an appeal in Washington?
Anthem (BCBS) generally has 30 calendar days to respond to a Level-1 appeal. If denied, you have 60 days to request external review. Separately, Washington's prompt-payment statute gives payers 60 days to respond to a clean claim (RCW 48.43.005) — a different deadline governing claim payment, not the appeal decision.
Does MHPAEA apply to Anthem (BCBS) in Washington?
Generally, yes — for Anthem (BCBS)'s group health plans. Federal MHPAEA applies to Anthem (BCBS)'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.
Where do I mail or fax a Anthem (BCBS) appeal?
Mail to Anthem Blue Cross Appeals Unit, P.O. Box 60007, Los Angeles, CA 90060. You can also fax to 1-866-755-2680. This address is the same nationally, including for Washington providers.
