== What it represents ==

In Care's FHIR-aligned model, a charge item definition maps to the '''ChargeItemDefinition''' resource. It holds:

* '''Identity''' — a title, a facility-scoped slug used to look it up, and a version number
* '''Pricing''' — a stack of price components: a base rate plus any surcharges, discounts, taxes, and informational lines
* '''Rules''' — how discounts are applied, and whether a charge raised from it can still be edited afterwards
* '''Classification''' — an optional category and tags that organise the facility's catalogue

The key distinction is that a charge item definition is the ''template'', not the bill. It describes what something should cost in general; the actual money owed for a specific patient on a specific day lives on a [[Concepts/Charge Item|charge item]]. Think of the definition as the menu price and the charge item as the line on the receipt.
