RFK Jr. and Dr. Oz Flag Over 1 Million Suspicious Obamacare Enrollments Lacking SSNs Amid Broader Federal Fraud Crackdown

Health and Human Services Secretary Robert F. Kennedy Jr. and Centers for Medicare & Medicaid Services Administrator Dr. Mehmet Oz announced that more than 1 million individuals were enrolled in Affordable Care Act (Obamacare) marketplace plans without Social Security numbers on file, highlighting what they describe as a major vulnerability to fraud in the program. The disclosure came via a video posted on X on June 27, 2026, as part of the Trump administration's intensified efforts to address waste, fraud, and abuse in federal health programs.

The officials pointed to broker-assisted sign-ups through HealthCare.gov that lacked SSNs and often involved zero premiums paid, labeling them as suspicious. An HHS issue brief referenced in reporting specifies roughly 1 million such enrollments flagged for further scrutiny. Kennedy described the situation as 'a glaring warning sign for fraud' and criticized prior administrations for weakening program integrity measures.

This revelation aligns with wider administration actions, including crackdowns on duplicate ACA-Medicaid enrollments (estimated at 1.6 million in some analyses) and phantom enrollments where no claims were filed. Related reporting notes enrollment drops of about 1.2 million from a base of 24.3 million as potentially tied to eligibility reviews rather than solely premium increases.

Critics and some coverage question the scale, noting that while verification gaps exist, not all flagged cases equate to confirmed fraud. Nonetheless, the focus ties into systemic issues of identity verification in entitlement programs, with ongoing multi-agency efforts involving CMS, OIG, FBI, and DOJ targeting sophisticated schemes in Medicare, Medicaid, and ACA markets.
