The most regulated claim in American medicine, run by one operating system.

California’s medical-legal market is growing faster than the reforms meant to contain it. Every report, deadline and bill in it is governed by statute — which is exactly the work an agentic operating system can carry and a physician should not have to.

Defend This

Before opposing counsel reads your report, Chiron plays opposing counsel — then drafts the rebuttal.

QME report, panel to signature

From panel request to a signed §4628 report: Chiron drafts each section, checks the twelve required elements, and you sign the declaration.

Statutory clocks, counted

UR, IMR, QME panel, P&S, PR-2, §4603.2 and §4622 — counted in the right kind of day, with alerts before they lapse.

Late-payment penalties, counted

California’s self-executing late-payment penalty and interest are computed on every bill, under the right regime — §4603.2 or §4622.

Personal-injury narrative report

The narrative report the patient’s attorney asks for — history, mechanism, baseline, treatment and your causation opinion — drafted from the chart.

AI that discloses itself and never claims a licence

Every AI output carries a deterministic AB 3030 / AB 489 disclosure, and any licensure-implying phrasing is rewritten before you see it.
