Service · Medical Chronologies

Page-cited treatment timelines, in minutes.

The spine of every demand, IME, and life care plan.

A medical chronology is the foundation of medical-legal casework — and the single most time-consuming document to build by hand. CaseOS reads every page across every provider, isolates related treatment, and assembles a chronological, citation-backed timeline you can defend line by line.

The manual way

How chronologies get built today

  1. A paralegal or legal nurse reads hundreds — sometimes thousands — of pages across multiple providers.
  2. Dates, diagnoses, procedures, and providers get hand-keyed into a spreadsheet or Word table.
  3. Gaps and duplicate records are caught manually, if at all.
  4. Every assertion has to be re-found later for the demand, deposition, or expert review.
One public PI customer story cited a 50% decrease in chronology review time after automation. Chronology work is the spine of causation, damages, and negotiation leverage — and the slowest thing on a case manager's desk.

  • Treatment-gap and duplicate-record flags
  • Isolates injury-related treatment from unrelated history
  • Exports to .docx in your firm's format
  • Handles handwritten notes and poor scans

What CaseOS surfaces while it builds the timeline

Medical Chronologies — your questions

How is this different from a paralegal-built chronology?

Same output, a fraction of the time — and with completeness checks a manual build usually misses. Your team reviews a cited draft instead of assembling one from scratch.

Can I trust the dates and facts?

Every entry links to the exact source page and line. Click any fact to see the original record — nothing is asserted without a citation.

What can it read?

PDFs, scans, images, and handwritten notes — including the messy, multi-provider record sets that arrive out of order.
