What’s available in Mercer Island

A center is a normal commute from here

Bellevue is about 4.2 miles away, which is a school-run sort of distance rather than an expedition. Families in Mercer Island can realistically use a center for peer and classroom-readiness goals while keeping in-home sessions for the routines that only happen at home.

Coverage itself is set statewide, not locally. Apple Health covers medically necessary ABA for eligible children anywhere in Washington, and Washington’s autism insurance law reaches private plans issued in the state. Your address changes which providers can reach you — it doesn’t change whether you’re covered.
