VA signs $775.72 million ambient AI contract; Heidi raises $340 million for agents; robotic thyroid ultrasound tested; AMA presses CMS on prior auth deadline

The Department of Veterans Affairs (VA) on Tuesday selected Abridge and Knowtex for a five-year ambient AI enterprise contract with a $775.72 million ceiling across all eligible vendors, Abridge announced and Nextgov reported. The contract is a multiple-award vehicle; the ceiling is a maximum across every vendor eligible to compete for task orders, and money is awarded one task order at a time. The VA began piloting both scribes in October 2025, according to Nextgov. Abridge said its platform is live at more than 75 VA medical centers on both of the department's record systems, in primary care and about a dozen specialties. The VA has published no results from its pilot.

The same day, Heidi, a scribe company, raised $340 million: $100 million of equity at a $900 million valuation and a $240 million facility from General Catalyst. The company's pitch, reported by HIT Consultant, is that the scribe was a first step and that the next is agents that prepopulate order sets, draft referrals and assemble the chart before the visit, with a clinician approving before any action is taken. In Boston, Jane Moran, Mass General Brigham's chief information and digital officer, told the World Medical Innovation Forum that the system is "not allowing autonomous AI across different platforms." The Massachusetts Nurses Association rallied outside the forum's hotel, and about 4,000 Brigham nurses vote Thursday on authorizing an open-ended strike.

In other developments, a Shanghai group reported in npj Digital Medicine a prospective multicenter trial of a fully autonomous robotic thyroid ultrasound that avoided about three-quarters of on-site exams and missed about a fifth of biopsy recommendations; Jefferson Health said its ambient AI rollout saved 1 million clinician hours in its first year and set a target of 10 million by 2028; the American Medical Association (AMA) asked the Centers for Medicare & Medicaid Services (CMS) to hold payers to the Jan. 1, 2027, electronic prior authorization deadline; and the Food and Drug Administration (FDA) updated its list of AI-enabled devices Tuesday to say "over 1,600," up from the 1,500 cited in this site's long read. The Senate Health, Education, Labor and Pensions (HELP) Committee hears from Dr. Heidi Overton, the nominee for FDA commissioner, on Thursday at 10:30 a.m. Eastern time. Colorado's attorney general faced a Wednesday deadline for a revised draft of the state's automated-decision and chatbot rules, and the rulemaking page had not posted one as of Wednesday morning. California's governor has seven days left to act on four health AI bills.
