Today, Dart Health releases automatic processing for supplemental files in Data Nexus. Supplemental files add the details your roster file doesn't carry, such as contact or insurance information from another system, without resending the whole roster. When a supplemental file matches a file type Dart has set up for your group, Data Nexus now applies it to your roster as soon as you upload it.
Member data rarely lives in one system. Names and birth dates come from HR, while member IDs and plan details sit in an insurance portal. Until now, combining those exports meant merging spreadsheets by hand or waiting for our team to apply the extra file.
How it works
- Choose Send a supplemental file on the upload page, then pick which file it is from your group's list of file types
- Data Nexus matches each row to a person already on your roster and applies the update
- The upload page shows the result, including anyone in the file who isn't on your roster yet
It adds detail and never takes anyone away
A supplemental file names only some of your people, so Data Nexus never draws conclusions from who is missing:
- It updates only the people the file names. Nobody is added, and nobody is removed for being absent.
- It never changes the four fields that identify a person: member ID, date of birth, first name, and last name
- If a file would end eligibility for a large share of active members, you confirm first.
- A blank cell clears that value. A column that isn't in the file leaves the value alone.
- The latest file wins for each field, so two files covering different columns both stick
When a file doesn't fit
- People who aren't on your roster yet are counted and listed, with the fix: send a primary roster that includes them, then upload the file again
- A file that doesn't match the type you chose is held for our team to review by hand
Data Nexus is SOC 2 Type II and HIPAA compliant.
