Medical Chronologies

Medical Chronology Services Compared: Nurse-Reviewed Vendors, AI Software, and In-House Prep

A medical chronology service takes a set of medical records and returns a dated, source-cited timeline of care that a legal team can use to prepare a case. The term covers three different ways of getting that timeline: an outside vendor whose staff read the records and build it, software that builds it and your team checks it, or a paralegal or nurse consultant inside the firm who does the work by hand. The deliverable looks similar from all three. They differ on who reads the records, who checks every entry against its source page, how long you wait, and what you pay per case.

This guide compares the three on those four points, lists the vendors that publish prices, and ends with the questions to ask before you commit a caseload to any of them. For a definition of the document itself, see the explainer on AI medical chronologies.

What Each Delivery Model Hands Back

Outsourced service Software In-house
Who reads the records The vendor's reviewers, often nurses, nurse-attorneys, or physicians The software, with your paralegal or attorney reviewing the output Your paralegal or legal nurse consultant
Who is responsible for checking entries against the source page The vendor, under its own quality process Your firm Your firm
Typical turnaround 48 hours to 7 business days, longer for large or disorganized files Minutes to about an hour Days to weeks, depending on page count and staff load
How you pay Per page, per hour, or per case, often with a minimum Per page credit, per case credit, or a monthly plan Staff time
What you get A finished chronology, sometimes with a narrative summary, delivered as a document or inside the vendor's portal A chronology you can edit, with a page citation on each entry A chronology in whatever format the firm uses
Where Superinsight sits Builds a chronology from uploaded records in about an hour with a source page citation on every entry; your own attorneys verify it, with medical experts available to review

Until recently the choice was between a vendor and your own staff. Software now produces a draft chronology with a page citation on every entry in about an hour, so most of the remaining work is review.

Vendors and Tools That Publish a Price

Most medical chronology companies quote per engagement.

Provider Model Published price Turnaround Who checks the output
LezDo TechMed Outsourced service Casewise: $100 flat for up to 100 pages, then $0.75 per page to 500 pages, $0.40 to 1,000, $0.30 to 2,000, $0.20 above that. A treatment timeline is a $100 add-on per case. Monthly contracts run $0.25 to $0.40 per page with a $4,500 monthly minimum 48 hours standard; 24 hours for a 20% surcharge The vendor; the site states a 99.8% accuracy rate and names CLNC-credentialed nurses and physicians among its reviewers
Record Grabber Outsourced service $30 per hour for a basic chronology (about 220 pages per hour), $40 per hour for a medium chronology and summary (about 50 pages per hour), $50 per hour for a high-level chronology and summary (about 35 pages per hour) 2 business days for basic; 5 to 7 business days for medium and high The vendor; reviewer credentials are not stated
Expert Institute AI draft with physician review A per-page rate; the number is not published "A few days" A physician on the vendor's team
InPractice Software $100 for 1,000 page credits, with no subscription and no expiry Minutes Your firm
Superinsight Software Free evaluation; plans starting from $250 per month About an hour for a cited report Your own attorneys, with medical experts available to review

Per-page rates from an outsourced service usually sit on top of a flat or minimum charge, so a 300-page file at LezDo's casewise rate costs $100 for the first 100 pages plus $150 for the next 200, before the $100 timeline add-on. Hourly rates from a service depend on the pages-per-hour figure the vendor quotes for each tier, which is why Record Grabber's $50 tier can cost more than its $30 tier by a factor of ten on the same file.

Providers Without Public Pricing

LMI staffs chronologies with RNs, RN/JDs, certified legal nurse consultants, and MDs, and quotes per engagement. Wisedocs pairs an AI chronology with clinical QA and sells mainly to carriers, third-party administrators, and defense counsel. U.S. Legal Support offers an AI-generated record summary through its client portal. LevelShift builds chronologies with its own staff and does not sell software. LMI, Wisedocs, and U.S. Legal Support publish neither a rate nor a turnaround, so budget a call before you can compare them with the table above.

Turnaround and Who Signs Off

The turnaround figures above describe two different things. A service's 48 hours or 5 business days ends with a finished chronology, already checked by the vendor. Software's hour ends with a draft, and the checking is still ahead of you.

When a nurse reviewer company delivers a chronology, the vendor stands behind the entries, and a mistake is a vendor problem until it reaches a deposition, where it becomes yours. When software delivers a draft, the firm is the reviewer of record from the first minute. The practical consequence is that a software chronology should carry a page citation on every entry, so the person checking it can open the source page in one click. A chronology without citations takes longer to verify, whichever model built it.

For a firm that already has a paralegal doing this work, the comparison is simpler. The seven-step method for building a chronology by hand takes the same inputs either way. Software removes the extraction and ordering steps and leaves the inclusion decisions and the verification pass, which need a person who knows the case.

Which Model Fits Which Case

Case type What the chronology has to do Model that usually fits
Single-incident personal injury, one or two providers Establish the first post-incident visit, the escalation of care, and any pre-incident treatment to the same body part Software, reviewed by the handling paralegal
Workers' compensation with many providers and a long treatment history Reconcile overlapping records from several facilities and keep the sequence straight across years Software for the first pass, with a nurse consultant on the inclusion decisions
Medical malpractice Reconstruct a short window in fine detail and support a standard-of-care opinion An outsourced service with physician review, or software plus the firm's retained expert
Social Security or VA disability Show functional limitations over years of treatment and tie them to the records that document them Software, since the volume is high and the review standard is documentary
Mass tort or multi-plaintiff Apply one template consistently across hundreds of files Software with a fixed field set, or a service with a volume contract

High volume and page counts favor software. A chronology that has to carry a clinical opinion needs a service with credentialed reviewers. A firm that needs both can run software for the timeline and send the finished chronology to a nurse consultant or expert for the opinion, which is usually cheaper than having the expert build the timeline.

What It Costs to Switch

Firms rarely change chronology providers mid-case, so the switching cost shows up at the start of the next one. Four things carry over badly.

  1. Format. Every vendor has a house template. If the firm's demand letters, mediation briefs, or expert transmittals are built around one layout, a new provider means reformatting or retraining.
  2. Links to source pages. A chronology delivered as a static PDF loses its connection to the records. One delivered inside a vendor's portal keeps that connection only while the firm keeps the account.
  3. Prepaid balances. Page credits, case packs, and annual plans are sunk once bought. Check expiry terms before buying in bulk.
  4. Open matters. A file that is half-processed with one provider usually has to finish there.

Before signing with any of the three models, get answers to these six questions.

  1. What exactly is the billing unit, and what counts toward it: pages received, pages after duplicate removal, or hours?
  2. Is there a minimum charge per case or per month?
  3. What is the turnaround for a 500-page file and for a 5,000-page file, and what happens to the price when records arrive in batches?
  4. Who reads the records, and what are their credentials?
  5. Does every entry cite the source page, and can the firm open that page from the entry?
  6. What format does the chronology come in, and can the firm edit it without going back to the provider?

Where Superinsight Fits

Superinsight is AI medical chronology software for law firms. A firm uploads the records and receives a chronology in about an hour, with each entry citing the page it came from. The firm's paralegal or attorney verifies the draft against the cited pages and refines it in plain English, with medical experts available to review.

It fits firms whose chronology volume moves month to month and whose paralegals already review vendor chronologies. The cited pages matter most when the chronology is going into a deposition or to an expert. Firms that have no one to review a draft will get more from a service with credentialed reviewers, and can still use Superinsight to produce the timeline that reviewer starts from.

Evaluation is free, so the comparison can be made on one of your own files. Plans start from $250 per month.

Frequently Asked Questions

What do medical chronology services include?

A dated timeline of medical events built from the records, usually with the provider, the encounter type, the findings, and a reference to the page each entry came from. Many services add a narrative summary, an index of providers, or a list of missing records. The scope varies by vendor, so confirm whether summaries, indexing, and duplicate removal are included or billed as add-ons.

How much do medical chronology services cost?

Published rates in October 2026 run from $0.20 to $0.75 per page for outsourced review, $30 to $50 per hour for hourly chronology services, and $0.05 to $0.10 per page for self-service software. Most vendors with credentialed reviewers quote per engagement. Page count, how organized the records are, the number of providers, and the deadline all move the final figure.

How long does a medical chronology service take?

Outsourced services publish turnarounds of 48 hours to 7 business days for a standard file, with surcharges for 24-hour delivery. Software returns a draft in minutes to about an hour. Large or disorganized files take longer under both models, and records that arrive in batches add time.

What is a medical chronologist?

A person who builds medical chronologies for a living, usually a paralegal, a legal nurse consultant, or a nurse working for a record review company. The title describes the task, so credentials vary. For a chronology that will support a clinical opinion, ask whether the chronologist holds a nursing or medical license.

Can software replace a medical chronology service?

For the timeline itself, yes, provided someone at the firm reviews the output against the source pages. Software does not replace a credentialed reviewer's opinion on causation, standard of care, or apportionment. Firms that need that opinion usually pair software for the timeline with a nurse consultant or physician for the analysis.

How is Superinsight different from a medical chronology service?

A service builds and reviews the chronology before delivery. Superinsight builds it in about an hour with a source-page citation on every entry, your own attorneys verify it with the record open beside the draft, and medical experts are available to review it.
