Microsoft expands Dragon Copilot with prior-auth drafting and a partner marketplace
Before HIMSS26, Microsoft announced on March 5, 2026 that Dragon Copilot now connects to Microsoft 365 Copilot. A new Work IQ layer lets clinicians pull email, Teams, schedules and documents into the same assistant they use to write notes. Microsoft says the product can draft prior authorization requests from the chart and a payer's coverage criteria. It also opened a marketplace for third-party agents, with launch partners Optum, Regard, Humata Health and Canary Speech. The release also adds nursing flowsheet documentation, with a radiology integration in US preview. Microsoft says more than 100,000 clinicians use Dragon Copilot.
Why it's notable: One of the two biggest ambient scribe vendors is turning its note-taking tool into a general clinical assistant that takes on admin work like prior authorization. That changes what health systems are buying when they pick a scribe.
