| * Standards status: *[Trial-use](http://hl7.org/fhir/R4/versions.html#std-process) | [Maturity Level](http://hl7.org/fhir/versions.html#maturity): 4 | *Computable Name*:QICoreSubstance |

 
Profile of Substance for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors. 

"Must Have", "QI Elements" and "primary code path" are defined in the
[QI-Core Must Support section](index.md#mustsupport-flag).

**QI Elements:**
* code: (QI) If this describes a specific package/container of the substance

**Primary code path:**code

(PCPath) This element is the primary code path for this resource

**Usage** 
  See the [patterns](patterns.md) page for implementation and usage patterns.
