The final rule CMS-0055-F from the U.S. Department of Health and Human Services requires the reporting of the NCPDP Quantity Prescribed (460-ET) field for all Schedule II drugs on pharmacy claims as of September 21, 2020.
The MO HealthNet Division (MHD) completed system work to deny claims if the NCPDP Quantity Prescribed (460-ET) field is not populated for Schedule II drugs. Claims will deny with a reject code of ET - M/I Quantity Prescribed if the field is blank, has all zeros, or is missing. Pharmacies should work with their software vendors to capture the mandatory NCPDP Quantity Prescribed (460-ET) field on all Schedule II drug claims.
