Guidance on how to interpret the contents of this table can be foundhere
| 0. Identifier | |
| Definition | An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers. |
| Short | Tipo de dato para identificar un paciente en ChileAn identifier intended for computation |
| Comments | Variable de identificación |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Is Modifier | false |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 2. Identifier.extension | |
| Definition | An Extension May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
| Short | ExtensionAdditional content defined by implementations |
| Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |

| Slicing | This element introduces a set of slices on Identifier.extension. The slices areUnordered and Open, and can be differentiated using the following discriminators: |
| 4. Identifier.extension:digitoVerificador | |
| Slice Name | digitoVerificador |

| Summary | true |
| Requirements | Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers. |

| 8. Identifier.type | |
| Definition | Tipo de documento definido para RUN A coded type for the identifier that can be used to determine which identifier to use for a specific purpose. |
| Short | Tipo de documento RUNDescription of identifier |
| Comments | This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type. |

| 10. Identifier.type.coding | |
| Definition | A reference to a code defined by a terminology system. |
| Short | Code defined by a terminology system |
| Comments | Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true. |

| Definition | Sistema mediante el cual se obtienen los códigos para un determinado tipo de documento The identification of the code system that defines the meaning of the symbol in the code. |

| Comments | En la URL del sistema se describe el set de códigos. Por ejemplo si se desea usar Cédula de identidad el código es NNxxx en donde xxx corresponde al identificador del país según la norma iso3166-1-N. Dado lo anterior si fuera Chile, el tipo de documento sería NNCL. En el Caso de Usar un Pasaporte este no requiere identificar país de origen dado que este es un elemento adicional, por lo que independiente del país el código será PPT según el VS indicado The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously. |

| 18. Identifier.value | |
| Definition | Valor del RUN The portion of the identifier typically relevant to the user and which is unique within the context of the system. |
| Short | Número RUNThe value that is unique |
| Comments | If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe. |

| Definition | The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged. |
