Nice work. And I’m not sure I remember seeing the Journal team up with an outside journalism organization for a story, so this is interesting:
The Wall Street Journal, together with the nonprofit Center for Public Integrity, obtained a 5% sample of all Medicare billing, but was unable to form an accurate picture of self-referring urology groups’ treatment patterns from the sample. The Journal subsequently obtained 100% of these groups’ billings from the Department of Health and Human Services for an additional fee. The Journal agreed not to publish billings of individual doctors. Instead, it is restricted to analyzing groups of 10 or more physicians.
