Catastrophic Illness, Your Tribe, Your Coverage

Catastrophic illness events, including a cancer diagnosis, a premature birth, or an organ transplant, are the highest-stakes moments in any health plan's financial life. For self-funded tribal health plans, they are also the moment when the structural adequacy of the plan becomes visible in ways that routine operations never reveal. This article, by Tyler Moore, examines how tribal self-funded health plans handle these events and where the most common gaps appear.

The first gap is stop-loss structure. Most self-funded plans purchase specific stop-loss insurance to cap their liability on individual large claims, but stop-loss policies vary significantly in their terms, including what counts toward the specific deductible, how the aggregate works, what conditions are excluded or lasered. Many tribal plans are underinsured against catastrophic individual claims without knowing it, because stop-loss structure was set based on historical claims patterns rather than prospective risk modeling.

The second gap is network adequacy for specialized care. Catastrophic illness often requires treatment at specialized centers, including cancer programs and transplant facilities, that may not be in the tribal plan's network or that require prior authorization workflows the plan has not built. The practical result is that members face access barriers at the worst possible moment, and the plan faces financial exposure from out-of-network claims that were not properly managed.

The article also addresses the administrative dimension: when a tribal member faces a catastrophic diagnosis, who is helping them navigate the plan? Most self-funded tribal plans do not have case management resources in place, leaving members to manage the administrative complexity of a major illness on their own, with predictable consequences for both outcomes and plan costs. Moore's argument is that the case management gap is as consequential as the stop-loss gap, and often more immediately addressable.
