List member enrollments

Lists a member's benefit enrollments across every employer — benefit type and product, employer, carrier, plan, tier, employee deduction, employer contribution and total premium, the individual enrollment coverage boundary (coverage_end), the separate pre-effective cancellation boundary (cancelled_date), and the distinct benefit plan-year boundary (plan_year_coverage_end) used to determine whether the plan year itself has ended, the date the enrollment record was created (issued_date, the value Ops labels Issued on, reported for every row whatever the member answered), the window the member could answer in -- which never opens before the enrollment was issued, so a row issued mid-open-enrollment starts its window on its issue date -- whether a qualifying life event would currently be required for reissue under the product/open-enrollment rule, enrollment/open-enrollment window, and two statuses: election_status (what the member answered) and policy_status (what became of their coverage, null unless they enrolled). Every row includes a stable enrollment ID and the exact employer and benefit plan-year IDs used to fetch that row's plan-year detail. The full list is returned across all states so the client derives active plans (effective and upcoming) and the enrollment history from those per-row statuses. For an organization caller the rows are scoped to companies in that organization's book; a member (self/household) or Vitable Admin sees all enrollments. A member not visible to the caller returns a 404.
