Question 1

Where does LineupMD data come from?

Accepted Answer

We ingest the official NPPES data dissemination file published by CMS (Centers for Medicare & Medicaid Services), plus Open Payments, Medicare Utilization, and Part D Prescribing data — all publicly available government datasets.

Question 2

How fresh is the data?

Accepted Answer

The NPI dataset is refreshed monthly with weekly incremental updates. Open Payments and Medicare data are updated annually by CMS.

Question 3

Is NPI data legal to use for sales outreach?

Accepted Answer

Yes. NPI data is public information maintained by a federal agency. It is not protected by HIPAA (it contains no patient data) and is freely available for any commercial purpose.

Question 4

How is LineupMD different from the free NPI Registry?

Accepted Answer

The CMS NPI Registry API limits you to 1,200 results per query, has no radius search, requires exact NUCC taxonomy codes, and has rate limits. LineupMD indexes the entire 8M+ database with instant search, practice size intelligence, and enrichment from Open Payments and Medicare data.
