Duplicate, contradictory, and outdated evidence
Preserve every original, identify the exact page and difference, compare source, date, scope, and question, and add an accurate correction or newer source when appropriate. Never hide or alter unfavorable evidence.
Overview
Do not delete, rewrite, or hide a source because it is duplicated, unfavorable, old, or inconsistent. Preserve the original, identify the exact page and difference, determine whether the records address the same time and question, and add an accurate clarification or newer source when appropriate. Preserve both sources before comparing Some apparent conflicts are extraction errors, copied history, different time periods, or different questions. Software may flag a possible difference, but it cannot decide credibility, evidentiary weight, legal adequacy, or which source VA must accept.
Create a source comparison log
Synthetic comparison. Quote only what is needed to identify the difference and cite both pages. Item A Item B Exact difference Same date and question Source to verify Next step Clinic note, page 4 Personal timeline Onset year differs Yes Original note and calendar Clarify approximate date 2022 treatment note 2026 examination Severity differs No; different dates Both originals Label the time period
Classify the difference before reacting
A neutral classification is not a finding about credibility or weight. Classification Meaning Exact duplicate The files contain the same pages and content; keep an authoritative original and any version actually submitted. Overlap Two sets share pages, but one may contain additional visits, attachments, or corrections. Different period Both sources may be accurate for different dates or stages of the condition. Different question The sources may address different theories, diagnoses, body sides, or functional questions. Possible factual error A source may list a wrong date, side, branch, diagnosis, medication, or history; preserve it and seek correction. Possible contradiction Two sources address the same fact, time, and question but give incompatible accounts; identify the conflict without deciding which controls. Outdated for one purpose An older record may not describe current severity but can remain relevant to onset, diagnosis, treatment, or history.
Verify the original page
Open the source Do not rely on OCR, an AI extraction, a copied timeline, or a summary. Read the context Check the surrounding paragraph, section heading, and record purpose. Check authorship and date Distinguish the clinician's finding from patient-reported or copied history. Check condition and side Confirm the exact diagnosis, body part, theory, and time covered. Check later corrections Look for an amendment, addendum, corrected report, or later source. One visit is not an entire history “No pain today” does not necessarily mean no pain during the month. A problem-list entry does not necessarily establish when a diagnosis was made. Preserve the record's actual scope.
Never alter an unfavorable source
Selective deletion can destroy context and credibility. If a source is wrong or incomplete, address the exact error and source openly. Keep the original and the correction together.
Use the source owner's correction process
A correction should not make the original disappear. Source Bounded correction path Medical record Ask the health system about its amendment process; preserve the original and any appended correction. Service or personnel record Use the custodian's correction or review process; do not alter an order, DD214, or personnel record. Your statement Provide a signed correction identifying the earlier statement, exact error, accurate information, source, and reason. Witness statement The witness controls their words and may correct their own statement; do not rewrite or sign for them. C&P report Record the factual concern, request the report, and follow current VA reporting and submission guidance; the examiner or VA controls an official addendum.
Compare evidence by role and time
Evidence can differ without being inconsistent. Evidence Time covered Question answered Role Service treatment note 2014 Complaint and findings Contemporaneous medical record Spouse statement 2018–2026 Observable sleep and function Lay observation Specialist opinion 2026 Diagnosis and medical relationship Medical opinion C&P report Exam date Requested findings and opinion VA claim examination Ask whether the statements were made near the event or years later. Distinguish one visit from a longer period. Record condition change, treatment response, flare-ups, and copied-forward history. Do not use a rule such as “newest always wins.” Do not demand identical language from lay and medical sources that answer different questions.
Compare medical-examination sources carefully
38 CFR 4.2 addresses interpretation of examination reports in light of the recorded history and reports with insufficient detail. Section 4.6 addresses evaluation of evidence. Those are adjudicative rules, not a Pathfinder result. Compare history used, records reviewed, tests, measurements, diagnoses, function, medical question, rationale, and addenda. Obtain the full report instead of judging a short decision summary. Do not declare an examination legally inadequate or decide which opinion has more weight. Record a precise question for the pending claim or decision review without selecting the lane.
Avoid duplicate VA submissions
Check the original receipt and available official evidence list. Compare file contents, not only filenames. Determine whether the new version adds a correction or page. Label corrected or expanded versions clearly. Keep the exact submitted copy even when a cleaner archive copy exists.
Common mistakes to avoid
Deleting an unfavorable original. Altering a source instead of seeking a correction. Calling overlapping exports exact duplicates. Calling different dates or questions contradictory. Assuming the newest evidence always wins. Trusting an extraction without opening the page. Uploading the same file repeatedly. Asking a witness to adopt your correction. Declaring legal error before reviewing the full report and decision. Treating a software conflict flag as VA's finding.
If the difference remains unresolved
If the difference remains unresolved The summary conflicts with the source. Open the original cited page. Read surrounding context. Correct the extraction or summary without altering the source. Treat the source as authoritative and preserve the software output only as a review aid. Two records cover different dates. Label each date and purpose. Check whether the condition changed. Avoid collapsing both into one severity statement. Use both records for the periods they actually describe. A source contains a factual error. Preserve the original. Identify the exact error and supporting source. Use the record owner's correction process or an honest statement under your own name. Keep the original and correction linked; never edit the source to make the conflict disappear. The conflict appears in a decision. Read the complete evidence list and reasons. Identify how the decision addressed each source. Separate existing-record questions from new evidence. Use current review guidance and the notice-stated date; this article does not choose the review lane. Preserve both sources, page references, dates, scopes, and exact differences. No current Pathfinder screen implements this complete workflow.
