Building reproducible analytics that help federal agencies protect Medicare from improper payments while improving access, with every numerical claim traced to a persisted result file from public CMS data.
Eight Medicare program integrity projects covering prescriber risk, opioid prescribing, drug waste, durable medical equipment, telehealth, hospital billing, home health and hospice, and county level access equity. The full analytical universe spans more than forty million Medicare beneficiaries, prescribers, providers, and counties.
Why this work matters to the United States
Improper payments cost the Medicare program roughly fifty-seven billion dollars in fiscal year 2025, including about twenty-eight point eight billion dollars in fee-for-service Medicare alone. This portfolio builds reproducible, public-data methods that federal agencies and their contractors can deploy directly to find improper billing and close access gaps.
Substantial merit, national importance
Reducing Medicare improper payments is a standing priority for CMS, the HHS Office of Inspector General, and the GAO. Methods released openly serve the whole field.
Well positioned to advance it
Eight completed projects, each with a reproducible pipeline, a public preprint, a public code repository, full claims traceability, and real-world adoption.
A national benefit to proceed
The value is national and method based, realized through public release rather than tied to any one employer, job offer, or labor certification.
Work
Eight Medicare program integrity projects, each with a dedicated technical page, figures, and downloadable report.
