- UnitedHealth deployed an AI tool called nH Predict to deny post-acute care claims for elderly Medicare Advantage patients — despite their doctors saying care was medically necessary. The AI has a 90% error rate on appeal, meaning nine in ten denials are ultimately reversed. A federal class action lawsuit alleging breach of contract is ongoing, with a judge ruling the appeals process was so obstructed it was effectively "futile."
- Internal documents alleged that employees who deviated from the AI tool's denial recommendations faced discipline or termination — embedding the denial-first practice into the company's culture. One 74-year-old stroke patient whose coverage was repeatedly denied accumulated over $70,000 in out-of-pocket costs before dying at a care facility.
- A February 2024 ransomware attack on UnitedHealth subsidiary Change Healthcare exposed the medical and personal data of approximately 192.7 million Americans — the largest healthcare data breach ever recorded. Stolen data included Social Security numbers, diagnoses, medications, and financial information. The breach was enabled by a basic security failure: a critical system lacked multi-factor authentication. UnitedHealth paid a $22 million ransom in Bitcoin.
- The DOJ launched both criminal and civil fraud investigations into UnitedHealth's Medicare Advantage billing practices, focusing on systematic "upcoding" — submitting inflated or unsupported diagnoses to collect higher government payments. UnitedHealth confirmed in a July 2025 SEC filing that it is complying with both probes. Analysts describe this as the largest Medicare Advantage fraud investigation in U.S. history.
- The Justice Department sued to block UnitedHealth's $3.3 billion acquisition of home health provider Amedisys, alleging the deal would leave patients with fewer choices and nurses with fewer employers. The case ended in a court-approved settlement forcing UnitedHealth to divest at least 164 home health and hospice locations across 19 states.
