07:13 AM EDT, 07/09/2025 (MT Newswires) -- UnitedHealth Group's ( UNH ) UNH Medicare billing practices are being investigated by the US Justice Department's criminal healthcare-fraud unit, The Wall Street Journal reported Wednesday, citing people familiar with the matter.

The investigation includes how the healthcare giant asked doctors and nurses to gather diagnoses that boosted its payments, the report said.

Former UnitedHealth ( UNH ) employees said they were asked detailed questions by prosecutors in recent weeks about the company's attempts to push the documentation of certain lucrative diagnoses to ensure that medical conditions were identified, the report said.

UnitedHealth ( UNH ) did not immediately respond to MT Newswires' request for comment on the matter.
