Subject to modification by the VTH Director without approval.


To describe the assigning of DEA suffixes to VTH clinicians, this policy covers all VTH clinicians that have a need to prescribe/order controlled substances for treating VTH 
patients. If a VTH clinician does not have a personal DEA number registered to the VTH address, they may be assigned a suffix of the Hospital Director’s DEA number. This suffix will be 4 digits that are indicated in the HIS (Health Information System) to allow a generation of a report indicating the suffix assigned to each person.


  • DEA suffixes are only to be used for ordering controlled substances for VTH patients. They are not to be used for non-VTH purposes.
  • DEA suffixes will be assigned by a pharmacist when indicated on an onboarding form that one is needed and for all new house officers.
  • Once a personal DEA number or suffix has been entered in the HIS (Health Information System), the clinician will be given access to pin controlled substance orders.
  • When an exit form is generated for a clinician, a pharmacist will remove the DEA suffix assigned in the HIS (Health Information System), if applicable.

Procedure (if applicable)

  1. If a new clinician will need a DEA suffix, the onboarding form should indicate this. The pharmacist will then assign a suffix and add it to the doctor profile in the HIS (Health Information System). This will occur automatically for all new house officers.
  2. When an exit form is generated, a pharmacist will check if a suffix was assigned, and if so, delete it from the HIS (Health Information System)and/or the doctor profile will be deactivated in the HIS (Health Information System). 

Definitions (if applicable)
