| 0. Extension | |
| Definition | Patient age measure and unit Optional Extension Element - found in all resources. |
| Short | EEBase PatientAgeOptional Extensions Element |
| Control | 0..* |
| Is Modifier | false |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists()) |
| 2. Extension.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 managable, 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. |

| Short | identifies the meaning of the extension |
| Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. |

| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 8. Extension.value[x].value | |
| Definition | The value of the measured amount. The value includes an implicit precision in the presentation of the value. |
| Short | Numerical value (with implicit precision) |
| Comments | The implicit precision in the value should always be honored. Monetary values have their own rules for handling precision (refer to standard accounting text books). |
| Control | 10..1 |
| Type | decimal |
| Is Modifier | false |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| Summary | true |
| Requirements | Precision is handled implicitly in almost all cases of measurement. |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 10. Extension.value[x].comparator | |
| Definition | How the value should be understood and represented - whether the actual value is greater or less than the stated value due to measurement issues; e.g. if the comparator is "<" , then the real value is < stated value. |
| Short | < | <= | >= | > | ad - how to understand the value |
| Control | 0..1 |
| Binding | The codes SHALL be taken from QuantityComparatorhttp://hl7.org/fhir/ValueSet/quantity-comparator|5.0.0 (required to http://hl7.org/fhir/ValueSet/quantity-comparator|5.0.0)How the Quantity should be understood and represented. |
| Type | code |
| Is Modifier | true because This is labeled as "Is Modifier" because the comparator modifies the interpretation of the value significantly. If there is no comparator, then there is no modification of the value |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| Summary | true |
| Requirements | Need a framework for handling measures where the value is <5ug/L or >400mg/L due to the limitations of measuring methodology. |
| Meaning if Missing | If there is no comparator, then there is no modification of the value |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |

| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
| 14. Extension.value[x].code | |
| Definition | A computer processable form of the unit in some unit representation system. |
| Short | Coded form of the unit |
| Comments | The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system. |
| Control | 10..1 This element is affected by the following invariants: qty-3 |
| Type | code |
| Is Modifier | false |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| Summary | true |
| Requirements | Need a computable form of the unit that is fixed across all forms. UCUM provides this for quantities, but SNOMED CT provides many units of interest. |
