Medical chronologies

Medical records arrive out of order, duplicated and unpaginated. A medical chronology puts them back into time, one dated line per encounter, each tied to a page or Bates number, so anyone on your team can see the course of treatment in a single read.

What the work involves

  • Every encounter reduced to a dated entry: provider, complaint, findings, diagnosis, treatment and next step.

  • Provider and facility index with date ranges and record volumes.

  • Pre-existing condition and prior-injury entries separated from the incident-related course of care.

  • Gaps in treatment, non-compliance and inconsistencies identified with citations.

  • Billing and cost figures pulled out where the records support them.

What you receive

  • Medical chronology (dated, cited)
  • Provider and facility index
  • Narrative medical summary
  • Pre-existing condition analysis
  • Treatment gap note
  • Billing summary where records permit

Who it suits

  • Personal injury and mass tort practices
  • Medical malpractice teams
  • Workers' compensation and disability practices
  • Insurance defence and claims review

What we do not do

  • Medical opinions, causation conclusions or expert testimony

  • Any clinical judgement — we report what the record states

  • Record retrieval or provider chasing
