Requesting a Limited Use (LU) Code - Ontario
If a prescription for a medication that requires a LU code does not have the reason for use, the prescriber must be contacted.
To request an LU code:
- In Rx Detail, select the Extended tab.
- In the Prescription section, select the magnifying icon
beside the MR Code field. 
The Medical Reason for Use Codes window opens.
- Select Print. A letter to the patient’s prescriber containing a list of codes will be generated and must be sent to the prescriber.
- Select OK. The Medical Reason for Use Codes window closes.
- Select the Rx tab.
- In the SIG field, add Waiting for LU to the SIG. This indicates that the doctor has been contacted.
- Select Pend.
When the prescriber provides the LU code, they can be taken written or verbally. If taken verbally, be sure to document the date and time the LU code is given.
