Healthcare: what AI is really doing

AI in Healthcare.

Ambient scribes and comprehensive imaging triage are the two places AI now touches real money and real patients at scale, running in hundreds of health systems on paid contracts, and imaging just became the first AI diagnostic tool to get a Medicare add-on payment. Drug discovery and prior authorization are one step behind, funded heavily and running in production at specific customers but not yet proven at the scale their backers are pricing in. Patient facing chatbots are the wild card: adoption is enormous and mostly unsupervised, the safety regulator named that the top hazard in the field for 2026, and FDA's rulebook for generative AI devices is still a discussion paper whose comment window has just closed.

The game: we show you 6 things happening. You call each one real now, early or mostly hype. Then the receipts.

The scary part

What happens to jobs in Healthcare

What AI is already taking:

What stays human:

The physical exam, the procedure itself, and the conversation where a clinician tells someone their diagnosis are still entirely human, and no vendor in this briefing is trying to change that. What also stays human, by law rather than by choice, is the signature: courts and regulators are treating the physician's review of AI output as a duty that cannot be handed to the software.

Get better · 15 minutes

Fast, confident auditing of AI output under time pressure, the ability to spot the one wrong dose or missing negative in a note or a scan read before it reaches the patient, rather than rubber-stamping a document that reads as fluently as if you wrote it yourself.

Try this this week:

Pull one AI-drafted note or read from this week and grade it against ECRI's own hazard framing: check every medication dose, contraindication and negative finding against the source encounter rather than skimming for tone, and time how long that actually takes. That number, not the vendor's minutes-saved marketing figure, is your real workload.

Your move

If you're building

Enterprise ambient scribing is now a four-way war between Abridge, Ambience, Microsoft's Nuance and Epic's own built-in AI Charting, don't enter it head-on. The open space is narrower: revenue-cycle and appeals automation on the payer side beyond prior auth intake, and agentic patient intake/triage, which is still mostly voice-agent demos, not deployed infrastructure.

If you're investing

Watch retention, not the headline note-drafting demo: Abridge citing over 90% of clinicians who start using the product still using it later is the tell that it works day to day. Watch reimbursement too: Aidoc's Medicare add-on payment is the first for an AI diagnostic, and a second one is what turns clearance into a budget line. Red flag in a drug-discovery pitch: any deck that quotes Phase I success rates without also giving you the Phase II number, since Phase II is where AI-discovered molecules are currently performing at ordinary industry rates, not better.

If you work in it

This quarter, pull ten ambient-scribe notes and compare them against your own memory or the recording, specifically hunting for omitted negatives (a symptom the patient denied that never made it into the note), not typos. That is the actual audit gap, and it's a fifteen-minute check per chart, not a research project.

If you're upskilling

The valuable skill now is fast, confident auditing of AI-generated clinical output, catching a wrong dose or a fabricated contraindication before it reaches a patient, since courts are already treating the physician's review as the point where responsibility sits. First step: read your specialty's entry on FDA's public AI-enabled device list so you know which tools in your own workflow are actually cleared versus just marketed as AI.

Done. That was the whole industry.

What's actually changing

  1. 1

    Ambient scribes go from pilot project to clinical infrastructure

    How it works. A microphone in the exam room records the visit, and a model turns the conversation directly into a structured note inside Epic or Oracle Health, with the clinician editing rather than typing from scratch. Epic, the record system these tools write notes into, now ships its own built-in version, AI Charting, so the startups are selling into a platform that also competes with them.

    Why it matters. Less after hours charting for clinicians, but health systems are locking into a small number of vendors for a workflow that touches every visit, and one of those vendors is now the record system itself.

    What's overstatedVendors describe this as giving clinicians their time back. The receipts so far are about after hours charting going down, not about visit volume or patient outcomes changing.

  2. 2

    Imaging AI moves from one algorithm per disease to one model reading the whole scan

    How it works. Older radiology AI was a separate cleared product for each finding, one for pulmonary embolism, one for stroke. Aidoc's CARE foundation model reads a single abdominal CT for 14 conditions at once, and Viz.ai has stacked over 50 separate FDA clearances into one coordinated triage workflow across stroke, hemorrhage and aortic disease. Since October 1, Medicare has let hospitals bill an add-on payment for eligible use of Aidoc's tool, the first time CMS has given that designation to an AI diagnostic.

    Why it matters. Fewer incidental findings get missed and radiologists get one alert instead of fourteen separate tools pinging them, and hospitals now get partly reimbursed for it, but the diagnostic judgment for many conditions sits inside one company's model instead of being split across vendors.

    What's overstatedThe sensitivity and specificity numbers in the clearance are the trained validation cohort's numbers, not a guarantee of the same accuracy on the atypical case in front of a specific radiologist next Tuesday. And the add-on payment eases the cost of adopting the tool for eligible Medicare cases for three years; it is not proof the tool changes outcomes.

  3. 3

    AI-designed drugs reach the Phase III test that actually decides the argument

    How it works. Over 173 AI-originated drug programs are now in clinical development, up from roughly two dozen in late 2023. Insilico Medicine's rentosertib, discovered and designed with generative AI, became the first such drug to reach Phase III, in idiopathic pulmonary fibrosis, and Isomorphic Labs raised $2.1 billion to keep its own drug design engine running.

    Why it matters. Phase I success rates for AI-discovered molecules already beat historic pharma averages, but Phase I only tests safety. Phase II, which tests whether the drug works, is running at roughly the same success rate as ordinary drug discovery, so Phase III is the round that tells everyone if the AI premium is real.

    What's overstatedPitches lean on the 80 to 90 percent Phase I success rate. That number is about safety, not efficacy, and the efficacy number, Phase II, is not currently beating the old way of doing things.

    Payer AI starts reading prior authorization requests, with a proposed federal deadline pushing the plumbing to catch up

    How it works. AI models from vendors like Anterior and Cohere Health read the clinical note against the coverage policy and auto-clear requests that match, sending only the ambiguous cases to a nurse or physician. A 2026 CMS proposed rule would require payers to run this over standard FHIR APIs rather than fax and portals, with electronic prior authorization for drugs from October 2027.

    Why it matters. This is the fix for the paperwork that the AMA says delays care for most physicians, but it also means an algorithm is now the first reader on a decision that can block a patient's treatment.

    What's overstated"AI never denies care" is the standard vendor line, describing where they've chosen to draw the product's scope now, not a technical ceiling on what the same model could be pointed at tomorrow.

CMS, 10 Apr 2026 ↗
  5. 5

    Chatbots become the default first opinion for doctors and patients, largely unsupervised

    How it works. OpenEvidence is a free, ad-supported clinical question answering tool built for physicians; in January its CEO, Daniel Nadler, claimed it was used by more than 40% of US doctors. Separately, tens of millions of ordinary patients ask general-purpose chatbots for medical advice with no clinical guardrails at all.

    Why it matters. Adoption on both sides is real and fast, but the safety regulator ECRI just ranked chatbot misuse the top health technology hazard for 2026, and the first lawsuit over a chatbot's medical advice contributing to a patient's injury is now in court.

    What's overstatedOpenEvidence markets itself as built "for doctors," but a free, ad-supported model answering clinical questions is structurally the same product patients use unsupervised, just aimed at the users it describes as "verified physicians." Aiming it at doctors doesn't remove the hallucination risk underneath.

    FDA starts drafting rules for generative AI devices after clearing over a thousand narrower ones under old rules

    How it works. The FDA has cleared well over a thousand AI-enabled devices, almost all through the 510(k) pathway built for comparing a new device to an existing one. Generative and agentic AI devices, including foundation models like Aidoc's, don't fit that comparison cleanly, so in August 2026 FDA published a discussion paper asking how to evaluate them; the comment window closed October 19, 2026. In parallel, FDA's TEMPO pilot is letting some AI devices (four so far, including Cadence and Limbic) reach patients without marketing authorization.

    Why it matters. Companies are already shipping foundation-model medical devices faster than the category built to evaluate them exists. What FDA decides now that the comment window has closed will set the evidence bar for the next wave of these products.

    What's overstatedThis is explicitly a discussion paper, not a rule and not binding guidance, and TEMPO is a pilot, not an approval. Coverage calling either one FDA's new "AI regulation" is ahead of what the agency itself has said it is.
