/// The resource ChargeItem describes the provision of healthcare provider
/// products for a certain patient, therefore referring not only to the product,
/// but containing in addition details of the provision, like date, time,
/// amounts and participating organizations and persons. The main usage of the
/// ChargeItem is to enable the billing process and internal cost allocation.
///
/// A ChargeItem is typically generated automatically or semi-automatically
/// whenever a billable event occurs during patient care, such as the
/// performance of a procedure, the dispensing of a medication, or the use of
/// a device or facility resource. It captures who or what performed the
/// service, when it occurred, the quantity and pricing information, and the
/// organizations that requested and performed the service, as well as any
/// override reasons applied to standard pricing rules. Downstream systems
/// aggregate ChargeItem instances, typically via an Invoice or similar
/// billing resource, to produce claims or patient statements.
///
/// # Related resources
///
/// - The `subject` of a ChargeItem is usually a
///   [`Patient`](crate::r5::resources::patient::Patient), and the `encounter`
///   field commonly references an `Encounter` during which the service was
///   rendered.
/// - Pricing and reason fields such as `code`, `bodysite`, `reason`, and
///   `override_reason` are represented using
///   [`CodeableConcept`](crate::r5::types::CodeableConcept).
/// - The `performer`, `enterer`, `cost_center`, `requesting_organization`,
///   and `performing_organization` fields link to actors via
///   [`Reference`](crate::r5::types::Reference).
///
