| 0. Extension | |
| Definition | This cross-version extension represents SubstanceAmount from http://hl7.org/fhir/StructureDefinition/SubstanceAmount|4.0.1 for use in FHIR R4B. |
| Short | Chemical substances are a single substance type whose primary defining element is the molecular structure. Chemical substances shall be defined on the basis of their complete covalent molecular structure; the presence of a salt (counter-ion) and/or solvates (water, alcohols) is also captured. Purity, grade, physical form or particle size are not taken into account in the definition of a chemical substance or in the assignment of a Substance ID |

| Slicing | This element introduces a set of slices on Extension.extension. The slices areUnordered and Closed, and can be differentiated using the following discriminators: |
| 4. Extension.extension:amount[x] | |
| Slice Name | amount[x] |
| Definition | This cross-version extension represents SubstanceAmount.amount[x] from http://hl7.org/fhir/StructureDefinition/SubstanceAmount|4.0.1 for use in FHIR R4B. |
| Short | Used to capture quantitative values for a variety of elements. If only limits are given, the arithmetic mean would be the average. If only a single definite value for a given element is given, it would be captured in this field |

| Slice Name | amountType |
| Definition | This cross-version extension represents SubstanceAmount.amountType from http://hl7.org/fhir/StructureDefinition/SubstanceAmount|4.0.1 for use in FHIR R4B. |
| Short | Most elements that require a quantitative value will also have a field called amount type. Amount type should always be specified because the actual value of the amount is often dependent on it. EXAMPLE: In capturing the actual relative amounts of substances or molecular fragments it is essential to indicate whether the amount refers to a mole ratio or weight ratio. For any given element an effort should be made to use same the amount type for all related definitional elements |

| Definition | An Extension May be used to represent additional information that is not part of the basic definition of the element.
