Claims-Denial Practice Case

This is a fictional, synthetic learning case for Lumyn FDE School. Aster Health, NorthLake, Summit Health, the people, claims, dates, systems, and metrics below do not represent a real customer or patient. The case contains no PHI. Treat every passage as evidence with the stated scope and limitation; do not invent missing facts.

Use this pack when you cannot use live field evidence or a sanitized retrospective. It supports a synthetic-practice branch through all ten missions and the field capstone. Practice evidence can demonstrate reasoning, not customer approval, production readiness, operating ownership, stakeholder skill, or field observation.

Case brief

Aster Health has funded a twelve-week pilot to reduce the time required to correct inpatient medical-necessity denials. The sold brief describes automatic corrected- claim resubmission for NorthLake and Summit Health. Discovery begins after signing. The delivery team must decide in ten business days whether a safe bounded kickoff is possible.

Staged evidence reveal

Use these source files in order. Each source passage has one canonical location; this hub intentionally does not repeat later evidence.

1. Mission 1: inherited brief, sponsor assertion, and operator observation
2. Mission 2: policy conflict and exact-build adapter test
3. Mission 3: measured baseline, decision event, and economics
4. Missions 4–5: mechanism and system-boundary design stop
5. Mission 6: candidate evaluation evidence
6. Mission 7: trusted-boundary and recovery evidence
7. Mission 8: later exact-candidate and scoped-disposition evidence
8. Mission 9: operating-review evidence
9. Mission 10: transfer and change-currentness evidence

Complete the current mission artifact before opening the next source or consulting the matching section of the annotated strong answer. The complete sequence is available to facilitators by following all nine links.

Learner tasks

1. Complete the ten mission artifacts using only supported claims or explicit unknowns.
2. Preserve conflicting and superseded evidence instead of repairing the story.
3. State where this synthetic pack cannot substitute for field evidence.
4. Compare your reasoning with the annotated strong answer after completing a first pass.
