Medical record chronology: frequently asked questions
Short answers, each linked to the page that covers it in full. The worked examples on this site use a synthetic file with no real patient.
Limits: Tool facts come from each vendor's own website, read 2026-11-12, and we have not tested those products. The time figures are published estimates from other sites, cited where used, and the worked example is synthetic.
Format, duplicates, gaps, time and cost
What columns should a medical record chronology have?
8: date, time, provider and facility, record type, what the record says, page, flag and reviewer comment. The format page gives the rules for each.
Should a chronology include my opinions?
No. Keep the record content in 1 column and your comments in another. The chronology is the factual base; the opinion goes in the report.
How detailed should each row be?
Detailed enough to answer the referral questions without opening the page, and no more. Quote key findings and negatives; summarize routine visits, such as a series of therapy notes, in 1 row with a date range.
Which date do I use when an imaging report was signed days after the study?
The study date. Note the signed date in the provider column. The dating rules cover addenda, late entries and undated pages.
Do I cite PDF page numbers or Bates numbers?
Either, but only 1 system per chronology, stated in the header. If the file has Bates numbers, use them, because other parties will.
What counts as a duplicate page?
An exact duplicate matches in text, stamps and handwriting. A page that differs in any way, such as a header or a signature date, is a near-duplicate and stays in. See duplicates.
How many days without records counts as a gap in care?
There is no single standard. Pick a threshold that fits the case before you look, such as 30 days for injury follow-up, write it in the header, and type every gap you find. The gap finder does the arithmetic.
How do I find records that should be there but aren't?
Read for references: a provider, test or visit mentioned in a note that has no records in the file. Flag each as missing and request it early.
How long does a chronology take by hand?
Published vendor estimates imply roughly 15 to 60 pages an hour, or 8 to 40 hours for files of a few hundred to over 1,000 pages. Use the calculator with your own numbers.
Is a spreadsheet good enough?
Yes for files under a few hundred pages. Use the template. Above that, indexing and duplicates take most of the time and software starts to pay off.
What does chronology software cost?
Published prices read on 2026-11-12 range from $25 plus 1 cent a page (capped at $100) to $299 a case, and from 5 to 15 cents a page for per-page tools. The tools page lists each with its source.
Who should check a chronology built by staff or software?
The physician who relies on it. Open the cited page for every row your opinion rests on, and a sample of the rest. See step 8.
