## Resource Profile: US Quality Core Medication Not Requested 

| | |
| :--- | :--- |
| *Official URL*:http://fhir.org/guides/onc/us-quality-core/StructureDefinition/us-quality-core-medicationnotrequested | *Version*:0.5.0 |
| Active as of 2026-05-15 | *Computable Name*:USQualityCoreMedicationNotRequested |

 
Negation profile of MedicationRequest for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors. 

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

The MedicationRequest and MedicationNotRequested profiles represent the positive and negative statements for a medication order. 

### Examples

 

| | |
| :--- | :--- |
| [Negation Example using Valueset](MedicationRequest-negation-example.md) | Medication not indicated; indicates that none of the medications in the given not done value set were requested. |
| [Negation Example using code](MedicationRequest-negation-example-code.md) | Medication not indicated; indicates that the medication specified by code was not requested. |

 

Both of these example instances meet measure intent for exclusion as defined in the following illustrative CQL (informational; not part of conformance requirements): 

```
define "Reason for Not Ordering Antithrombotic":
  ["MedicationNotRequested": "Antithrombotic Therapy"] NoAntithromboticDischarge
    where (NoAntithromboticDischarge.reasonCode in "Medical Reason"
      or NoAntithromboticDischarge.reasonCode in "Patient Refusal")
      and (NoAntithromboticDischarge.isCommunity() or NoAntithromboticDischarge.isDischarge())
      and NoAntithromboticDischarge.status in { 'active', 'completed' }
      and NoAntithromboticDischarge.intent = 'order'
```

For a more complete discussion of representation of negation within US Quality Core and quality improvement artifacts, see the [Negation in US Quality Core](general-requirements.md#negation-in-us-quality-core) topic.

**USCDI+ Quality Elements:**

* doNotPerform: (USCDI+ Quality) True if medication was not requested
* reasonCode: (USCDI+ Quality) (USCDI) Reason or indication for ordering or not ordering the medication
