A measure requires a very specific RxNorm code for a medication element that was ‘not done.’ For example, in CMS100, NQF142, the QDM component "Medication, Order not done: Medical Reason" for "Hospital Measures-Aspirin RxNorm Value Set" requires that the Element Code come from a value set that only contains very specific medications, doses and dose forms.
In practice, clinicians would NEVER capture that level of specificity for something not prescribed or not ordered, and forcing that specificity would imply a precision without clinical accuracy and in fact may cause clinical inaccuracy. We would request that instead we are provided “category level” codes (e.g. Aspirin) since that is all the measure should need and in fact is all the precision that is available in clinical practice.
