Guidance published 7 March 2019
Microtest cannot disable invalid codes within the system until they reach Phase 2 of SNOMED-CT implementation. Until then, users will still be technically able to add these codes to patient records.
Staff should be made aware that these codes (9Nu4 / 9Nu5) must not be entered into patient records.
Search to identify invalid codes
Use the Microtest search function to check for any patients with code 9Nu4 added after 11 Oct 2018. Instructions on how to use the search function are provided in the Microtest website.
You should schedule this search to happen on a regular basis, until you are confident that invalid codes are no longer being used.
If results are found, review the patient record(s) to check that the code was added after 11 October 2018. (Sometimes the report will pick up entries added as part of a GP2GP transfer to a new practice, when in fact the code was added to the patient record some time ago.)
