SCENARIO

You've joined CarePath, a managed care coordinator. Each episode has a primary provider, and specialists can be added temporarily — so responsibilities legitimately overlap. Responsibilities are also reassigned mid-episode, and billing depends on who was responsible at the time of each service.

your model must answer

01The provider responsible for a patient at the time of a given service?
02A timeline of all responsibility changes for a patient during an episode, with start and end times for each provider?
03By provider and month, number of services billed, total allowed amount, and share of episode days covered?

This exercise’s brief could not be loaded.The guided questions and their model answers come from the review service. It looks like it is not reachable — start it with pnpm dev:api and reload.The canvas below still works, so you can model now and run the review once the service is up.
