The Wire

What you'll be asked today — and what to say back. A couple that caught my eye this morning; the rest are on the wire.

Twenty-five health systems just built their own AI agents inside Epic. Were we in the room?

Becker's Hospital Review · Sep 16, 2026

Epic ran its second Agent Factory Build-a-Thon in Verona, and twenty-five health systems showed up to build their own clinical and operational agents on top of the EHR. The headcount isn't the interesting number — the venue is. Epic isn't shipping twenty-five agents itself; it's hosting twenty-five customers who are building them, which means the agent layer is getting defined inside Epic's tooling and governance rather than by the point-solution vendors those systems would otherwise have bought from. Skip the next one and the shape of the interface gets settled without you — a year from now your integration story is "we plug into what they built." The question worth bringing back isn't whether to attend. It's who on our side owns agent design as a named job, because that's the ticket in.

The ED diagnostic AI was safe and accurate. Clinicians stopped using it inside four weeks anyway.

Corrado Magnino · Sep 16, 2026

A randomized trial of a multi-LLM ED diagnostic support system found it worked — and watched clinician use fall from 44% of cases to near zero over four weeks. The Nature Medicine RCT randomized 1,146 patients; the tool was fully integrated into the chart with no extra data entry, and it still saw use in fewer than half the intervention-arm cases on day one, declining from there. The investigators point to workflow interruption, no accuracy feedback loop, and the finding that should worry every CMIO: use dropped further during higher-workload periods, meaning the tool got abandoned exactly when it was needed most. The same roundup flags an amyloid cardiomyopathy risk model that hit only 0.14 positive predictive value in an unselected population, and an echo-based structural heart model whose performance dropped sharply outside its training cohort.

80/20The one thing that matters is the adoption curve, not the AUC. Every clinical AI business case you'll see this year reports accuracy at deployment and nothing about week four. Ask vendors for a usage-over-time chart from a live site. If they don't have one, they've never looked — and the pilot you're being sold has an expiration date nobody wrote down.

UnitedHealthcare just dropped prior auth on 1,700 codes. Does that actually change anything for us?

Wendell Potter · Sep 16, 2026

Almost nothing, and we should plan on that. Wendell Potter — who ran communications inside the industry — walks the math: the 1,700 figure appears to double-count the same codes across plan types, so it's likely 800 to 1,000 unique CPT and HCPCS codes, and by the company's own numbers it touches roughly 2% of medical services. The categories where denials actually concentrate — specialty and injectable drugs, GLP-1s, oncology regimens, cardiac device implants — are largely untouched. On the same October 1 effective date, UnitedHealthcare is adding new prior-auth requirements for certain genetic and molecular testing plus an oncology code. Cigna ran the same play in 2023 with a 25% reduction that landed under 4% of services. Nobody should be re-baselining authorization staffing on this announcement — that conversation is worth having now, not in January.

Six members of Congress just introduced a bill that names the MSO workaround directly. How exposed are we?

U.S. Senate · Sep 16, 2026

Introduction isn't passage, and this bill has no visible Republican sponsor, so the near-term odds are low. What matters is that it names the structure rather than the outcome: the management services organization arrangement that lets a non-physician entity own everything except the medical license is the explicit target, not a side effect. That's the same structure most PE-backed physician platforms — and a fair number of virtual-care companies — are built on. The practical move this quarter isn't legal strategy, it's inventory: which of our entities rely on an MSO or friendly-PC arrangement, in which states, and what each state's existing corporate-practice doctrine already requires. State attorneys general have been moving on this independently. Counsel should size the exposure before a bill with better odds shows up.

Hippocratic AI's best case wasn't a job someone already had. It was 1,700 patients nobody was working at all.

Lifers with Christina Farr · Sep 17, 2026

The framing worth stealing is copilot, autopilot, infinite pilot — and the claim from Hippocratic AI CEO Munjal Shah is that the real wins came from the third bucket: work nobody had the staff to attempt at all. One health system had 1,700 patients lost to follow-up on low-dose CT lung screening and had written them off; outreach got 252 scheduled, 180 through the door, nine significant findings, three cancers. The economic argument is the part worth repeating to a CFO: with fixed costs that large, a health system can't cut its way to solvency, so the honest AI case is capacity and revenue, not headcount reduction.

80/20The one thing that matters: every ROI number in that story came from work that was never on anyone's productivity report. Automate a task someone's already doing and you get a savings argument you have to defend against their salary. Automate a task nobody's doing and you get revenue with no incumbent to displace — which is why those deployments survive the second budget cycle and the copilots often don't.
