Thank you. For those who encounter same problem, available documentation not up to date so here’s what you should do:
- change post max and upload max to 80M (otherwise, you might get the “loading successful, 0 new, 0 updates” message after uploading RXnorm
- in open emr, admin\forms\lists
- manage lists drop down field, choose code types
- change RXCUI to active (otherwise, you’ll get “no active code set” message when trying to upload RXnorm)
- download monthly zip as instructed
- admin\coding\native data loads
- upload zip
