/// A clinical condition, problem, diagnosis, or other event, situation, issue,
/// or clinical concept that has risen to a level of concern.
///
/// The Condition resource is used to record detailed information about a
/// condition, problem, diagnosis, or other health matter that is of concern.
/// It can be used to record conditions that a patient has, is at risk of, or is
/// being managed for, and is central to problem lists, encounter diagnoses, and
/// clinical assessments in FHIR R5.
///
/// Typical uses include capturing a patient's active and historical problem
/// list, documenting a diagnosis reached during an encounter, and tracking the
/// clinical course of a condition over time through fields such as
/// `clinical_status`, `verification_status`, `onset`, `abatement`, and `stage`.
/// A `Condition` always refers back to the `subject` (usually a patient) for
/// whom the condition is asserted, and it may be linked to the `encounter`
/// during which it was identified or recorded.
///
/// # Related resources
///
/// - [`Patient`](crate::r5::resources::patient::Patient) — the individual who is typically the subject of a condition.
/// - `Encounter` — the clinical encounter during which the condition was noted or assessed.
/// - `Observation` — clinical findings that may support or evidence a condition.
/// - [`CodeableConcept`](crate::r5::types::CodeableConcept) — used throughout this resource for coded status, category, severity, and body site values.
///
/// # Examples
///
/// ```
/// use fhir::r5::resources::condition::Condition;
///
/// let value = Condition::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Condition = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
