THE DATA SHELF / 01
Choose your crosswalk. Inspect the structure.
Get back to the work that matters.
Bring legacy industry codes into the 2022 standard. A clean starting point for CRM updates, territory mapping, and database joins.
Connect FDA drug package codes to therapeutic groups through RxNorm. ATC levels 1–4, together in one file.
Secure checkout with Stripe. Your ZIP is available after successful payment. These are dated snapshots; future updates are not included.
SMALL DETAILS. BIG DIFFERENCE. / 02
Every download comes with the structure and provenance you need to understand what you’re joining.
Each crosswalk documents its unique key. Many-to-many mappings stay intact, so you can handle splits and combinations deliberately.
Source code text and NDC hyphens are preserved. Import identifier columns as text to keep spreadsheet software from changing them.
A metadata file records source URLs, the production date, the row count, and a SHA-256 checksum for the CSV.
BEFORE YOU DOWNLOAD / 03
A ZIP containing a UTF-8 CSV and a metadata.json file. After Stripe confirms your payment, you’ll return to a private download page. Save that page’s URL if you want to download again.
Yes. The files are ordinary, flat CSVs. In Excel, use Data → From Text/CSV and set code columns to Text. Check your CRM’s field names and import rules before loading. Both datasets are many-to-many crosswalks, so joining them may produce multiple matches.
No. This March 20, 2026 snapshot maps 164,012 of 248,601 NDCs (about 66%) to 627 ATC-4 groups. Some products have no mapping. It includes ATC levels 1–4, not level 5, and is intended for data analysis rather than clinical decisions.
No. Each price is a one-time payment for the dated snapshot shown. It does not include ongoing updates.
