Yes you can!
It is common for patients to see the same practitioner for the same treatment multiple times (weekly therapy sessions are common with our users).
If all of the information on your superbills is the same (same doctor, same treatment codes, same place of service, same price) except the date, all you have to do is tap to select multiple dates on the "Date of Service" screen, as in the example below.
On the final screen, you will see the amount that you paid for each visit, and the total amount that you paid for all of them.
Additionally, if you want to submit a new claim for a service that is identical to a claim that you have submitted in the past, you can clone an existing claim and just change the date of service for the new claim.
