Modeling Eligibility as a Pipeline, Not a Boolean

Product and content teams keep collapsing eligibility into a boolean. "Does X cover Y?" The answer users need is almost never a single bit. It is a pipeline with gates that fail independently.

A useful model looks more like this:

type EligibilityStage =
  | { kind: 'benefit_exists'; source: string }
  | { kind: 'medical_necessity'; evidence: string[] }
  | { kind: 'plan_rules'; contractor: string; requirements: string[] }
  | { kind: 'network_capacity'; inNetwork: boolean; accepting: boolean }
  | { kind: 'authorization'; status: 'pending' | 'approved' | 'denied' }

Each stage can pass while the next one fails. A page that only answers stage one trains users to stop early, then blame the system when stage three blocks them.

Render the stage, not the slogan

If your content or UI can only show one sentence, prefer the current blocker over the marketing claim. "Benefit exists under EPSDT for members under 21" and "prior authorization packet incomplete" are both true and point to different actions.

Stage	Good output	Bad output
Benefit	Name the rule and age/scope floor	"Yes, covered"
Plan rules	Link the handbook / policy fields	"Check with your plan" with no fields
Network	Separate in-network from accepting	"Provider accepts Medicaid"
Auth	List required documents	"Pending" with no next step

Why this shows up in family systems

Health and education benefits are full of these pipelines. Medicaid ABA coverage, IEP services, and private-pay cost estimates all share the same shape: a category-level claim, then contractor-specific rules, then capacity, then paperwork. Treating any of them as a boolean is a documentation bug.
