Who buys this list
Endoscopy equipment and reprocessing
Scopes, capsule systems, insufflation and reprocessing contracts are decided by the endoscopist and the ASC they own. Both are reachable from this file.
IBD biologics and specialty pharma
A prescriber universe with NPI numbers is what your data team asks for before a launch. This is that, with a verification date on the email column.
Colorectal screening and diagnostics labs
Stool based and blood based screening tests need referring physicians. Cut by state, work the region where your lab has coverage.
GI practice platforms and recruiters
GI is consolidating into large regional groups. Corporate development teams and recruiters both need named physicians with locations, and both get them here.
How many gastroenterologists are there in the US?

Questions buyers ask
The CMS Doctors and Clinicians national downloadable file, the Medicare enrollment roster, version Aug 18, 2026. Every gastroenterologist in it treats Medicare patients, which is a filter on its own: no lapsed enrollments, no phantom practices. Emails are added and verified by us, not bought from a broker.
Not on the verified rows. The email column is the gastroenterologist's own work address, matched to the practice domain and checked against the mailbox. The practice phone sits in its own column for the times you do want the front desk.
No verified count yet. This file's email column is built after you order and reaches you within a day at no extra cost, and only addresses that pass an SMTP check go in. Expect a minority of rows to get one: in our first test run, 55 of 400 cardiologists got a verified email (Sep 10, 2026). Every row keeps the practice city, state and ZIP. Most rows also carry a street address and a practice phone.
There is no ownership field in the CMS file, so no list built from it can tell you who owns an endoscopy center. The workable signal is multi location billing: 45% of this list bills from more than one address, which is the pattern for a physician with a practice plus a procedure center. Combine that with the practice name and you can build a target set in an afternoon.
Role addresses, catch-all-only domains and dead mailboxes are removed before you get the file, which is what keeps a cold send from wrecking a domain. If hard bounces still pass five percent on the verified column, we refund the $295 against your bounce report.
They are short. CAN-SPAM: no misleading headers or subject lines, a real physical address in every message, a working opt-out honored within ten business days. The law covers business-to-business email too, and it does not require opt-in. HIPAA does not apply, because provider records are not patient records. Sends into Canada or the EU fall under CASL and GDPR, and compliance there is on you.
