AI Chronology vs. LNC-Drafted Chronology: The Real Cost Math (2026)

By John Mahoney · Reviewed by a practicing physician · Last updated September 2, 2026 · 10-minute read

Disclosure: MedLegal AI sells chronology software, so we have an interest in the answer. We have tried to make the model honest against that interest: verification time is counted in full, the software's own limits are stated, and the section on when a nurse consultant wins is not a token one. Every input below is an assumption you can replace with your own number. Corrections: [email protected].

The comparison everyone gets wrong

The usual framing is "$19 per analysis versus $150 an hour," which is not a comparison at all. The software fee is the smallest line in the model. The line that decides the answer is the human time you still have to spend — because a chronology no one has verified against the record is not a work product an attorney can use, and Formal Opinion 512 says as much (our med-mal compliance checklist covers the verification duty).

So this model prices three workflows, not two, and it charges every one of them for the verification that a competent practice requires.

The three workflows

  1. LNC-drafted. A legal nurse consultant reads the full record and drafts the chronology. Verification is built in — the drafter is the verifier — but the attorney still reviews the product.
  2. Software-only. The tool drafts; nobody checks material entries against the page. We include this row to show what it costs, not to recommend it. It fails the competence standard for anything an expert will rely on.
  3. Hybrid. Software drafts with a page citation on every entry; a nurse consultant or trained paralegal verifies the material entries against the cited pages, corrects what is wrong, and adds the clinical flags software does not generate. This is the workflow most firms actually settle into.

Model assumptions (replace with yours)

InputValue usedBasis
LNC hourly rate$140Midpoint of the $100–$175 range independent LNCs commonly quote; firm-employed nurse reviewers cost less per hour but carry overhead
Paralegal hourly cost (loaded)$65Salary plus benefits and overhead for an experienced litigation paralegal; adjust to your market
Full-draft throughput75 pages/hourMidpoint of the 50–100 pages/hour commonly cited for chronology drafting; dense ICU flowsheets run slower, clean outpatient notes faster
Verification effort (hybrid)30% of full-draft hoursConservative. Verifying a cited entry is faster than finding the fact unaided; material entries are a fraction of all entries. Firms that verify only expert-relied entries report lower figures; we use the higher number
Fixed setup per case1 hourIntake, file organization, Bates confirmation — applies to every workflow
Software fee$19 per analysis (pay-per-use) or $49/month unlimited on the entry planOur current published pricing; comparable tools range from per-analysis to per-seat contracts — category comparison here
Why no vendor-specific numbers for competing tools or specific LNC firms? Rates and throughput in this space change with the market and the individual, and we will not publish a figure about a third party that we cannot verify on the day you read this. The ranges above are stable enough to model with; confirm your own vendor's numbers before you rely on them.

The math: three case sizes

Costs are for producing a verified chronology, before the attorney's own strategic review, which is the same in every workflow and is omitted. Setup hour is charged at the paralegal rate in every row.

Case 1 — 500 pages (single admission, outpatient follow-up)

WorkflowHoursLaborSoftwareTotalTurnaround
LNC-drafted1 setup + 6.7 draft$65 + $933≈ $1,0001–2 weeks (queue-dependent)
Software-only (not recommended)1 setup$65$19≈ $85Same day
Hybrid (LNC verifies)1 setup + 2.0 verify$65 + $280$19≈ $3651–3 days
Hybrid (paralegal verifies)1 setup + 2.0 verify$65 + $130$19≈ $215Same day – 2 days

Case 2 — 2,000 pages (multi-day hospitalization with imaging and consults)

*Very large records may need to be processed in parts; on the per-analysis plan that can mean more than one fee. Our files-over-80 MB limit is a real constraint at this size and we say so in the comparison guide.

What the numbers say — and what they do not

Run your own numbers

Full draft cost = Setup + (Pages ÷ PagesPerHour) × DrafterRate
Hybrid cost = Setup + SoftwareFee + (Pages ÷ PagesPerHour) × VerifyShare × VerifierRate
Per-case saving = Full draft cost − Hybrid cost

Example (2,000 pages, $140 LNC, 75 pp/h, 30% verify, $65 setup, $19 fee):
Full draft = 65 + 26.7 × 140 = $3,798
Hybrid = 65 + 19 + 26.7 × 0.30 × 140 = $1,205
Saving = $2,593

Break-even against the software fee alone arrives well under 300 pages on these inputs. The more useful exercise is sensitivity: move VerifyShare between 0.20 and 0.60 and see how quickly the answer depends on whether the tool cites the page.

When the nurse consultant still wins

A chronology is an extraction product. A legal nurse consultant sells judgment, and there are cases where the judgment is the point:

  1. Nursing standard-of-care analysis. Whether a fall-risk reassessment was due, whether a pressure-injury staging was documented correctly, whether an escalation policy was followed — these are opinions, not extractions, and the chronology is only their input.
  2. Handwritten and badly scanned records. Long-term-care and older physician-office charts still arrive as illegible scans. Extraction quality degrades, verification share climbs, and the model above stops holding. Have the consultant draft those sections.
  3. EHR audit-trail work. Reading late entries, edit histories, and access logs against the clinical narrative is specialist work; see our audit-trail guide. Software can surface the chronology those logs are checked against; it does not interpret the logs.
  4. When the consultant is also your expert. If the LNC will offer opinions in the case, having them build the chronology is part of forming the opinion, and the drafting hours are doing double duty.

The honest summary: the hybrid workflow does not replace the nurse consultant. It moves their hours from extraction, where software is faster, to verification and judgment, where they are worth the rate. Consultants pricing their own practice will find the same math from the other side in our LNC ROI guide.

Test the assumption that decides the answer

Everything above turns on one variable: how fast a human can verify an extracted entry. That depends on whether the entry links to its page. See the motion for yourself on a sample record before you set your own VerifyShare.

FAQ

How much does an LNC-drafted chronology cost in 2026?

Commonly $100–$175 per hour at 50–100 pages per hour, so a 2,000-page admission runs roughly $2,000–$7,000 before attorney review. Confirm rate and throughput with your consultant.

Is a software chronology cheaper once you count verification?

Usually, by 55–70% on the hybrid workflow at realistic verification assumptions — and by much less if the tool's citations are weak and verification takes longer.

When is the LNC still the better choice?

Nursing standard-of-care analysis, illegible or handwritten records, audit-trail interpretation, and any case where the consultant is also your expert.

What is the hybrid workflow?

Software drafts with page citations; a nurse consultant or paralegal verifies material entries against the cited pages and adds clinical flags. You pay software plus verification hours instead of full drafting hours.

How do I calculate my own break-even?

Use the formula above: full-draft cost minus (setup + software fee + verification hours × verifier rate). On typical inputs the break-even is well under 300 pages.
