Senate Democrats challenge OPM plan to collect health data on 8 million federal workers

Six Senate Democrats, led by Senators Adam Schiff and Mark Warner, are demanding that the Office of Personnel Management suspend its plan to collect claims-level health data on up to 8 million federal workers, retirees, and their families. While OPM asserts the database is necessary to combat fraud and waste, lawmakers argue that the agency's pseudonymization measures are insufficient to prevent re-identification. The dispute intensifies privacy concerns amid reports that the Pentagon is searching medical records to identify transgender troops.

OPM health data collection plan

• ▪The Office of Personnel Management published a December 2025 proposal requiring insurers in federal health benefit programs to provide monthly reports with identifiable enrollee health data.
• ▪The Office of Personnel Management stated that the collected health data would be used for oversight activities, program integrity, cost evaluation, and fraud prevention.
• ▪The Office of Personnel Management revised its proposal in June 2026 to pseudonymize records by removing direct identifiers like names, Social Security numbers, and street addresses.

Privacy risks for federal workers

• ▪The Office of Personnel Management's data collection plan covers up to 8 million federal employees, retirees, spouses, children, and other family members.
• ▪The Office of Personnel Management's plan permits sharing sensitive health data with law enforcement, the Department of Justice, and other government agencies under specific conditions.
• ▪The Office of Personnel Management's proposal allows the agency to re-identify pseudonymized health records when reasonably necessary to accomplish an authorized purpose.

Security vulnerabilities of pseudonymization

• ▪Senate Democrats warned that the Office of Personnel Management's plan to retain health records for 30 years materially increases the risk of internal misuse or external security breaches.
• ▪Senate Democrats argued that combining birth year, sex, zip code, provider names, service dates, diagnoses, and drug information creates a detailed longitudinal history linkable to specific individuals.

Democratic lawmakers' opposition

• ▪Six Senate Democrats, led by Sens. Adam Schiff and Mark Warner, sent a letter on September 16, 2026, urging the Office of Personnel Management to suspend its health data collection plan.
• ▪Senate Democrats demanded that the Office of Personnel Management publish a field-by-field necessity analysis justifying the statutory purpose for collecting each type of health data.
• ▪Senate Democrats noted that the Office of Personnel Management has not responded to their initial opposition letter sent in April 2026.

Trump administration data politicization

• ▪The Trump administration has eliminated 38 datasets and altered or disrupted hundreds of others across various federal agencies since returning to office.
• ▪The Equal Employment Opportunity Commission plans to stop collecting EEO-1 reports, which require companies to provide demographic data on their workforces broken down by race, ethnicity, sex, and job title.
• ▪The Department of Defense has begun searching protected medical records of service members to identify and remove transgender people from the military.
