How claims adjusters use medical record review

An adjuster with 140 open files cannot read 2,000 pages on each of them. The question is which files need a clinician's read, and what to do with it.

Medical record review in claims handling is the practice of having a clinician read the medical records on a file and return an organized account of what they show. Carriers have done this for decades through in-house nurse reviewers, and most large carriers still do. The pressure now comes from volume and from cost: nurse hours are expensive, in-house teams are sized for average caseloads, and the files that most need a clinician's read are the ones that arrive in a surge. What follows is where the review changes the decision, drawn from how adjusters actually use it.

Reserving

The first reserve is set from the incident report and whatever medical records have arrived, which is usually the emergency department visit and not much else. The reserve gets revisited when the demand arrives, often a year later, and the gap between the two is where reserve adequacy problems arise. A record review at the point where a meaningful production exists, typically when the claimant has been in treatment for a few months, gives the adjuster the diagnosis as the treating providers actually documented it, the trajectory of treatment, the prior conditions in the record, and the treatment gaps. Files with a surgical recommendation, a specialist referral that has not resolved, or a prior claim on the same body part get identified early enough for the reserve to reflect them.

Evaluating the demand

A demand package tells the claimant's story with the records selected to support it. The adjuster's job is to check the story against the full record, and a chronology built from the complete production does that mechanically. It shows the treatment the demand's specials claim but the notes do not support, the improvement documented between the visits the demand quotes, the gap the demand does not mention, and the prior complaint in the primary care record that the demand's narrative left out. Just as often it confirms the demand is well founded, which is also useful, because a file that should settle is cheaper to settle now.

Deciding on an IME

An independent medical examination costs real money and takes weeks to schedule, and ordering one on every disputed file is neither affordable nor persuasive. The record review is the screening step. A chronology with a clear causation question, a documented prior condition, or a discrepancy between histories tells the adjuster which files an examiner can actually help with, and gives the examiner a complete summary to work from. A chronology showing consistent treatment, objective findings that fit the mechanism, and a clean pre-incident record tells the adjuster that an examination is likely to confirm the claim, and the money is better spent settling.

Workers' compensation

Compensation files add the questions of work relatedness, work capacity, and maximum medical improvement, and the record answers all three over time. The work status notes, the restrictions as they change, the therapy progress, and the treating physician's statements about MMI are scattered through the file and easy to lose. A chronology puts them on one line each, in order, so the adjuster can see when restrictions lifted, when progress plateaued, and whether the treating physician's opinion on MMI matches the record of treatment. Utilization review and IME referrals both become more targeted when the timeline is in front of the person making the referral.

Files that do not need a clinician

Most files do not. A soft-tissue claim with six weeks of chiropractic treatment and a clean discharge does not need a nurse to read it, and a review service that recommends otherwise is selling something. The files that benefit are the ones where the record is large, the diagnosis is contested, the prior history is unknown, the demand is high relative to the visible injury, or surgery has been recommended. An adjuster who orders review on those files and not the rest gets the benefit without the budget problem.

What to look for in a reviewer

Three things decide whether a review is worth what it costs. Who reads the record: a nurse practitioner, physician assistant, or physician reads a chart differently from a coder or a paralegal, and the difference shows in what gets flagged. Whether every page is read: sampling the specialist records and skipping the rest is how the prior complaint in the nursing note gets missed. And whether the review states what the record shows rather than what the reviewer thinks about it. An adjuster needs the facts organized; the opinions belong to the examiner or the defense expert, and a review that mixes the two is harder to use and harder to defend if the file ends up in litigation.

Questions people ask

When in the life of a claim should medical record review be ordered?

Once a meaningful production exists, usually a few months into treatment, and again when the demand arrives if the record has grown. Reviewing at first notice, on an emergency department visit alone, rarely changes anything.

Which claims benefit most from a clinician's record review?

Large records, contested diagnoses, unknown prior history, demands that are high relative to the visible injury, and files where surgery is recommended. Routine soft-tissue files with short treatment and clean discharge usually do not need it.

Does record review replace an IME?

No. It screens for it. A chronology identifies the files where an examiner can resolve a real question and gives the examiner a complete summary to start from, and it identifies the files where an examination would likely confirm the claim.

Is a NaviCase review an expert opinion?

No. The Record Summary and Summary + Analysis state what the record shows, with flags for gaps, prior conditions, and discrepancies. Causation and reasonableness opinions come from a retained examiner or expert.
