Questions buyers ask.
Where does the network data come from?
From network directories that insurers publish, combined with national provider registries. Each answer shows its source type and the date the data was read.
How current is it?
Network data is refreshed on a regular cycle, and every answer carries its own date, so you always know how fresh it is.
Do you handle patient data?
No. InPlan holds provider and plan data only. No patient information is sent to us or stored.
Can we get the data as files?
Yes. State and national data files carry the same fields and evidence as the API. The Scale plan includes bulk data files.
