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

What we do not do

Any clinical judgement — we report what the record states
Record retrieval or provider chasing

Questions we are asked
- How are entries cited?
- To Bates number where the production is Bates-stamped, otherwise to file name and page. Every line in the chronology can be traced back to a page in minutes.
- Can you work to our chronology format?
- Yes. Send a sample and we build to it — column order, date format, abbreviations and all.
