Menu guidance in the source record

The contact webpage lists option 1; its linked August 2025 reference lists option 2. Listen to the current menu rather than relying on one shortcut.

Menus can change. No live call verification is claimed.

Published calling advice

Premera suggested 7–8 a.m. or after 2:30 p.m. Pacific for provider customer service.

Applies to Washington provider customer service at 877-342-5258. This is the insurer’s dated guidance, not measured caller-report statistics or a guaranteed wait.

This archived 2023 article may be outdated. Use the current contact page for hours; its menu guidance conflicts with the older article and reference sheet. No current queue measurement is available.

Not researched for this route

The current dental FAQ directs providers to secure Availity tools and customer service for benefit-specific questions. The dedicated dental option-2 assertion came from form 012822 dated June 2018 and is retired from this dialable field because current dental-specific routing was not independently corroborated. The general provider contact page still publishes the inherited base number, now with option 1; it is a general fallback, not proof of a dedicated dental menu. Use the member card and current menu for the actual plan. No assertion that the historical base number is disconnected.
