How to merge duplicate patient files
If a patient appears twice in Otto, their orders, prescriptions and reminders are split across two files. Otto Support merges duplicates for you: here's what to send and how to prevent new ones.

Why duplicates happen
Most duplicate files come from one of these:
- An EHR or practice-management integration, such as Visual-Eyes, creating a new patient instead of matching an existing one.
- A data import that brought in a patient who already existed in Otto.
- A new file created by hand for a patient who was already in Otto under a slightly different name or email.
Ask Otto Support to merge them
Merging is done by Otto Support. There's no merge button in Otto. Email help@ottooptics.io (or use live chat) with:
- The patient ID of each file you want merged.
- Which file to keep as the primary. The other file's orders, prescriptions and history move into it.
- Your location name, if your clinic has more than one.
Please send IDs only. Don't email patient names, dates of birth or prescription details.
Avoid creating new duplicates
- Search before you create. Before adding a new patient, search Patients by last name, phone and email.
- Use the EHR browser extension. It flags patients who already exist in Otto before you create an order. See how to use the Otto EHR browser extension.
- Update rather than re-create. If a patient's details change, edit their existing file. See how to update patient information.
Good to know
- Duplicates matter beyond tidiness: refill reminders, follow-ups and order history are tracked per file, so a split patient can get the wrong reminder or none at all.
- If an integration keeps re-creating the same patient after a merge, tell Otto Support which integration you use so we can look into the cause.
