Supplemental record review software that compares new medical records to the existing file automatically. Each supplemental production is deduplicated against the records you already have, summarized on its own, and flagged wherever it agrees with the existing file, conflicts with it, or adds something new. [Test a file ](https://medrecords.ai/test-a-file/?src=product-supplemental-record-review) [Book a demo](https://medrecords.ai/demo/) Supplemental batch · Adams, T. — right knee · Case #IME-4812 vs 342-page file Incoming records — compared on arrival Ortho follow-up note AGREES · with p.212 Repeat MRI report NEW · added to timeline Work-status letter CONFLICTS · vs p.198 Progress note — already produced DUPLICATE · removed Delta summary drafted · conflicts cited on both sides Deduped on arrival Matched against the entire production, not just the batch Agree · conflict · add Every new record flagged for how it changes the file Cited both ways Conflicts point at the old page and the new one ### Deduplicated against the whole production. A supplemental batch usually re-sends half the file. New pages are matched against everything already produced — not just each other — so what lands in review is only what's genuinely new. Exact and near duplicates removed at intake Batch page count vs. genuinely-new count, stated up front Batch intake Pages in the batch — received Already in the file — removed as duplicates Genuinely new — routed to review Reviewers read **the new pages** , not the whole batch again. Drafted on arrival Delta summary — supplemental batch One new imaging study, 2 follow-up visits, and a revised work-status letter. The repeat MRI report is new to the file supp. p.9; the work-status letter conflicts with the restriction previously documented p.198. timeline updated new events marked ### What's new, summarized on its own. The batch gets its own summary: new visits, new diagnoses, new work-status entries. A reviewer who already knows the file reads the delta, not the record from page one. Delta summary drafted per batch, citations included Timeline updated in place, new events marked as supplemental ### Flagged where it agrees, conflicts, or adds. Each new record is compared against the existing analysis. Where a new note corroborates the file, it's flagged as agreement; where it contradicts a date, a finding, or a prior report's conclusion, the conflict is stated with citations to both pages. Conflicts with the prior report surfaced, not buried Corroboration flagged too — useful evidence either way Dispositions Ortho follow-up note — AGREES Repeat MRI report — ADDS Work-status letter — CONFLICTS 3 dispositions, **every flag cited** . Conflict · work status Original — no restrictions noted file · p.198 Supplemental — lifting restriction supp. · p.9 Prior report affected flagged for update Old page and new page, 1 click each. Both sides cited ### A conflict is only useful if you can prove both halves. When a late-arriving record contradicts the file, the flag carries 2 citations: the original page and the supplemental page. What changed, and where, is source-linked on both ends — audit-grade, legally defensible, and ready to hand to whoever wrote the first report.

The comparison work happens on arrival, before a reviewer opens a single page. 01 Upload the supplemental batch The late production goes in next to the existing file — no manual matching or renaming. 02 Matched against the file Duplicates are removed against the whole production; new records are compared to the existing analysis. 03 Read the delta A cited summary of what's new, plus agree / conflict / add flags on every record — both sides cited. ### Who absorbs late records with it. The people for whom a supplemental production lands a week before the deadline. [ Law firms The late production before deposition, absorbed in hours instead of days. For law firms ](https://medrecords.ai/solutions/law-firms/) [ IME & QME evaluators Addendum requests answered from the delta, not a full re-review. For medical evaluators ](https://medrecords.ai/solutions/medical-evaluators/) FAQ ### Supplemental review, answered. A supplemental batch is treated as a comparison problem, not a new pile. It is deduplicated against everything already produced, summarized on its own, and each genuinely-new record is flagged for whether it agrees with, conflicts with, or adds to the existing file. Each new record's extracted content — dates, findings, work status, diagnoses — is checked against the file's existing analysis. Corroboration is flagged as agreement; contradictions are flagged as conflicts with the specific disagreeing content quoted and cited. If a new record contradicts something a previously drafted report relied on, that report is flagged for update, with the conflicting passage cited on both sides. The reviewer decides what changes; nothing is rewritten silently. The full production. Supplemental batches routinely re-send pages from earlier productions, so matching only within the batch would miss most duplicates. Anything already in the file is removed and logged before review begins. Yes. Every conflict flag carries 2 citations — the original page and the supplemental page — so the disagreement can be verified at both sources in one click each. ### Related capabilities Adjacent features on the same platform — every output source-linked and cited to page.
