Turned down by a plan in Washington?
We read the denial, check which of these rules reach that plan, and prepare the reconsideration request, the access-gap evidence and any regulator complaint the law supports; you sign and send them, and we track every deadline. Self-funded employer plans follow federal law, not Washington's. A rejection review is $249, credited toward a dispute.
