- Sunset of NCIt QuantityUnitOfMeasure (QUOM) codes for e-Prescribing
Surescripts will begin enforcing the updated QuantityUnitOfMeasure (QUOM) code list effective September 1, 2022, and will reject any E-Prescribing messages, except CancelRx messages, that contain a NCIt QuantityUnitOfMeasure code that has been sunset. This code set is referenced by the NCPDP SCRIPT Standard External Code List (ECL) v2017071 that is used in Surescripts E-Prescribing Solutions.
In preparation of the sunsetting of NCIt QuantityUnitOfMeasure (QUOM) codes, we have removed the codes listed below from the Unit of Measure dropdown in the Add Prescription / Medication window.

*NCIt – National Cancer Institute Thesaurus
**QuantityUnitOfMeasure is referred to as PotencyUnitCode in prior versions of the SCRIPT Standard.
