Here’s the short version of how we got today’s annual, NPI-level Medicare Part B “Physician & Other Supplier” files on data.cms.gov:
1) A 1979 court order blocked doctor-identifiable releases.
In Florida Medical Association v. HEW (M.D. Fla. 1979), a federal district court enjoined HHS from disclosing Medicare reimbursement amounts in ways that would identify individual physicians, largely on Privacy Act/FOIA Exemption 6 grounds. That injunction then cast a long shadow over data access for decades. (Justia)
2) Attempts to pry data loose in the 2000s ran into that injunction.
The nonprofit Consumers’ Checkbook (Center for the Study of Services) sued under FOIA seeking physician-specific Medicare payment data to build consumer tools. The D.C. Circuit sided with HHS in 2009, emphasizing both privacy concerns and the effect of the standing Florida injunction—so the data stayed closed. (Justia)
3) Wall Street Journal/Dow Jones pushed to vacate the old injunction.
After the WSJ’s “Secrets of the System” series, Dow Jones moved in the Middle District of Florida to lift the 1979 order. On May 31, 2013, Judge Marcia Morales Howard vacated the 33-year injunction, clearing the legal barrier that had long prevented physician-identifiable releases. News coverage at the time made the stakes clear for transparency advocates. (Reuters)
4) CMS consulted the public, then changed policy and published.
Following the 2013 ruling, CMS issued a formal Request for Public Comment on releasing physician data (Aug. 2013). In January 2014, CMS announced it would evaluate requests case-by-case, and in April 2014 it released the first “Medicare Provider Utilization and Payment Data: Physician and Other Supplier” Public Use File (covering CY2012). (CMS Downloads)
5) Annual releases have continued on data.cms.gov.
CMS now posts and refreshes the “Medicare Physician & Other Practitioners” datasets annually, with documentation describing content and methods (utilization, allowed/paid amounts, charges) at the NPI × HCPCS × place-of-service level. (CMS Data)
Context notes
-
The 1979 Florida injunction was the primary legal obstacle; earlier courts and agencies treated it as a blanket prohibition until it was lifted in 2013. (foiaproject.org)
-
The 2014 release sparked a wave of analyses and commentary about strengths/limits of the data (e.g., specialty attribution, context for high billers). (Commonwealth Fund)
If you’d like, I can pull the specific CMS press notices and the first 2014 PUF’s “what changed” text next.

Prompt
CMS publishes an incredible annual database of all CPT code services paid to all physicians for Medicare Part B. The data includes the independent lab industry (non hospital lab tests). This data has been released since 2013 at data.cms.gov. it was released following litigation by Wall Street Journal and I recall perhaps a party called "Citizens Checkbook." Litigation under FOIA resumed in around 2010-2013 and revived topics that had been litigated some 10-20 years earlier. Can you summarize this history for me.
