/// An association between a patient and an organization / healthcare
/// provider(s) during which time encounters may occur.
///
/// EpisodeOfCare represents a period during which a managing organization
/// assumes a level of responsibility for a patient's care, potentially
/// spanning many encounters. It groups together the type of care, the medical
/// reasons and diagnoses being addressed, the care manager and care team, and
/// the accounts used for billing. In FHIR R5 it is commonly used to model
/// longitudinal programs such as disease management, specialist referrals, or
/// ongoing treatment relationships.
///
/// Clinically and administratively, an EpisodeOfCare acts as the umbrella
/// under which individual clinical events are grouped: each
/// [`Encounter`](crate::r5::resources::encounter::Encounter) that occurs
/// while the episode is active may reference this resource so that the
/// visits, orders, and results belonging to the same program of care can be
/// tracked and reported together. The `status` and `status_history` fields
/// track the episode's lifecycle from `planned` through `active` to
/// `finished` or `cancelled`, while `reason` and `diagnosis` capture the
/// clinical justification and the conditions being managed.
///
/// Related resources: the `patient` field references the
/// [`Patient`](crate::r5::resources::patient::Patient) who is the focus of
/// the episode, and the type/class of the episode, its reasons, and its
/// diagnoses are typically coded using
/// [`CodeableConcept`](crate::r5::types::CodeableConcept). See also
/// `CareTeam` and `Organization` for related workflow resources.
///
/// # Examples

/// use fhir::r5::resources::episode_of_care::EpisodeOfCare;
///
/// let value = EpisodeOfCare::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: EpisodeOfCare = ::serde_json::from_value(json).unwrap();
