How Surveillance Evidence Should Be Presented to an IME Physician

Surveillance can add information to an independent medical examination file, but a short clip rarely speaks for itself. The physician needs to know what was recorded, what was not recorded, how the file was handled, and which medical question the footage is supposed to inform.

The goal is not to steer the opinion. It is to give the examiner a fair opportunity to compare observed activity with the history, examination findings, diagnostic studies, treatment record, and reported limitations. That requires a complete package, a neutral cover memorandum, and enough time for a genuine review.

Start With a Complete, Neutral Surveillance Package

Provide the source material before the highlight reel

A compilation can help the physician find the relevant segments, but it should not be the only version supplied. Selected clips may omit the minutes before or after an activity, the frequency of pauses, failed attempts, changes in pace, or long periods when nothing occurred. Federal Rule of Evidence 106 is a federal trial rule, not an IME intake rule, but its concern about misleading impressions from material taken out of context explains why completeness disputes arise. Rule 106 also underscores why the sender should preserve context rather than assume the most dramatic clip tells the full story.

Preserve the source file and document any conversion

Keep the original file in the evidence custodian’s normal preservation system. If the physician needs a converted copy for playback, label it as a convenience copy and identify the software or process used to create it. Do not overwrite the original or strip available metadata merely to make the file easier to open.

The Scientific Working Group on Digital Evidence guidance for forensic video analysis identifies metadata collection, format conversion, and timeline reconstruction as technical video-examination tasks. Its guidance also discusses hashing results media for the case file. Those tasks belong with the party’s evidence or forensic workflow, not with the IME physician. The physician should receive enough information to understand which file was reviewed and whether it differs from the source.

Include the complete observation period

Send the full recording for each observation period when legally permitted and reasonably available. If a short excerpt is highlighted, identify the corresponding time in the full file. Include the investigator’s start and stop times, periods with no recorded activity, camera interruptions, and any known reason an observation ended.

No footage is not the same as no activity, and recorded activity is not a continuous measure of function. A complete log helps the physician understand the sample. It also reduces the chance that a later review reveals context that should have been considered from the start.

Build a chronology the physician can use

A physician should not have to search several hours of footage to discover which two minutes prompted the referral. Provide a simple index that points to the relevant segments while leaving the source material available for review.

Index the footage by time and activity

For each segment, list the date, local time, location if reliably known, file name, start and end timecode, and a short description of visible activity. Use descriptive language such as “walks from the residence to a vehicle while carrying a bag in the right hand.” Avoid conclusions such as “moves normally” or “proves full work capacity.”

If the investigator’s report supplies a fact that is not independently visible, identify it as information from that report. Do not blend it into the description as though the physician personally observed it.

Label gaps and unknowns

State what is not known. The distance, object weight, camera speed, terrain, identity, or duration may be uncertain. A person may move differently before or after the recorded interval. A camera angle may hide bracing, hesitation, or assistance.

Neutral labels make the evidence more usable. They let the physician explain whether an uncertainty limits the medical inference instead of forcing the reader to uncover that weakness later.

Give the Physician Medical Context, Not a Verdict

Match each clip to a medical question

Surveillance is collateral information. The American Academy of Psychiatry and the Law practice guideline notes that recordings may be reviewed as collateral material and that the potential biases of collateral sources should be considered. That guidance is written for forensic psychiatric assessment, but the practical distinction applies more broadly: a recording is one source among several, not a substitute for the physician’s specialty-specific analysis.

Connect the activity to the claimed limitation

Provide the medical records needed to understand the issue, including the relevant examination findings, imaging, treatment history, stated restrictions, job demands, and dates. MLP IME’s IME referral checklist advises organizing comprehensive records and highlighting information that helps the physician evaluate the case. The MLP IME discussion of ethics and boundaries also stresses complete records and disclosure of information gaps.

Match the dates carefully. Footage recorded before surgery, during an acute flare, or months after a reported restriction may have a different medical significance. Do not ask the physician to compare a clip with a limitation that was never in effect on the recording date.

Ask for analysis within the physician’s specialty

A useful question might ask whether the observed activity is medically consistent with a specified diagnosis, examination finding, or restriction, and why. It may also ask whether the footage changes any prior opinion and, if so, which opinion and on what medical basis.

A brief recording usually cannot establish whether someone can repeat an activity safely, sustain it through a workday, or perform it without later symptoms. Ask the examiner to distinguish what the footage supports from what it does not show.

Keep advocacy out of the referral memo

The AMA Code of Medical Ethics opinion on independent medical examinations describes the examiner’s role as assessing health or disability independently and objectively. A cover memorandum should support that role rather than announce the result the retaining party wants.

Describe what is visible

Use verbs and observable details. “The person bends at the waist and places a box in the trunk” is more useful than “the person shows no pain.” Pain, effort, endurance, and medical significance require analysis. Even when a clip appears inconsistent with a reported limitation, the memo should identify the exact statement or record being compared rather than apply a character label.

Avoid words such as fraud, fake, dishonest, exaggeration, or malingering unless the physician independently uses a medically appropriate term and explains the basis within the physician’s expertise. The referring party should not place that conclusion in the physician’s mouth.

Leave credibility conclusions to the proper decision-maker

The physician may discuss consistency between the footage and the medical record. The physician may also explain alternative interpretations and the limits of the observation. Credibility findings, legal intent, and ultimate claim decisions usually belong to the court, agency, carrier, or other authorized decision-maker under the applicable process.

This division protects the value of the medical opinion. It keeps the report centered on diagnosis, causation when within scope, functional findings, restrictions, prognosis, and other questions the physician was retained to address.

Decide When the Physician Should Review the Footage

If the footage arrives before the examination

Send it early enough for the physician to review the full package rather than watching a few clips between appointments. Confirm that the physician can open the files and understands the index.

Allow enough review time

Ask the physician or IME coordinator how much review time is needed. A long surveillance set may require additional scheduling or record-review time. Late delivery increases the risk of a rushed review, omitted material, or a report that does not identify the footage at all.

Some examiners prefer to review surveillance before the appointment so they can clarify a reported activity during the history. Others may prefer to take the history and perform the examination first, then review the footage before finalizing the opinion. Either approach can be documented. The important point is to agree on the sequence rather than let it happen by accident.

Record the review sequence

The report or file index should identify what the physician reviewed and when. In federal proceedings, Rule 703 addresses facts or data on which an expert may base an opinion, and Rule 705 recognizes that underlying facts or data may be explored on cross-examination. State rules may differ, but an accurate materials-reviewed list helps everyone understand the foundation of the opinion, especially if the physician may later serve as a medical expert witness.

If the physician did not review a file, do not imply otherwise. If only a compilation was reviewed, say so and explain whether the full recording was available.

If the footage arrives after the report

New surveillance does not automatically justify a supplemental opinion. First ask whether it is material to an issue the physician already addressed.

Explain why the new material is medically relevant

Identify the recording date, the opinion it may affect, and the specific activity at issue. Do not send a new stack of records and ask whether anything changes. The MLP IME article on when to request an IME report addendum lists surveillance that raises a specific medical question as one possible reason for an addendum and recommends identifying the dates and medical issue.

If the footage is cumulative or unrelated to the physician’s assignment, an addendum may add cost without adding clarity.

Request a focused addendum

Provide the complete surveillance package, identify the original report, and ask a narrow question. For example: “Does the activity recorded on May 14 change your opinion about the lifting restriction stated on page 12 of your report? Please explain the medical basis and any limits on the inference.”

Do not ask the physician to “correct” an unfavorable report unless there is an actual factual error. A supplemental opinion should show what new material was reviewed, what changed, what did not change, and why.

Preserve the IME Physician’s Role

Questions the physician can address

The examiner can compare observed movement with the history, physical examination, diagnostic findings, treatment course, and documented restrictions. The examiner can also discuss whether the footage is medically significant and whether more information is needed.

Focus on functional consistency

Ask about specific functions such as lifting, reaching, gait, transitions, hand use, or tolerance for a recorded activity. The question should identify the claimed limitation and its date. This keeps the response tied to evidence rather than a general impression.

The analysis should account for duration, repetition, pace, environment, assistance, and what happened outside the frame. A single successful movement may be relevant without establishing sustained capacity.

Ask the physician to state limitations

A well-supported report explains uncertainty. The physician can note that object weight is unknown, identity was assumed by the sender, image quality is limited, or the recording is too short to assess endurance. Those qualifications do not weaken a medical opinion. They show that the opinion stays within the evidence.

The physician should also identify whether the footage changes a diagnosis, restriction, causation opinion, or no opinion at all. “No change” can be a meaningful conclusion when it is explained.

Questions that belong elsewhere

Surveillance raises technical and legal issues that a medical license does not answer. The referral should keep those issues separate.

Separate video forensics from medical interpretation

Do not ask the IME physician to determine whether a file was altered, whether timestamps are accurate, or whether an enhancement method is reliable unless the physician has a separate, disclosed qualification for that work. SWGDE defines forensic video analysis as a scientific examination of video in legal matters. Technical questions may require a qualified video examiner.

Likewise, do not ask the physician to identify the recorded person from appearance alone. State the identity information supplied by the investigator or counsel and label any uncertainty.

Separate legal conclusions from medical opinions

Authentication, admissibility, discovery compliance, privacy, and the permissible use of surveillance are legal questions. Federal Rule of Evidence 901 illustrates the separate foundation required to show that an item is what its proponent claims, but controlling rules vary. The IME report should not be used as a shortcut around that foundation.

Counsel should decide what may be sent, what must be disclosed, and whether a protective order or other restriction applies. The physician can then address the medical question using the authorized material.

Use a Repeatable Submission Checklist

Check the evidence package before sending

A short quality-control review can prevent most avoidable problems.

Confirm completeness and traceability

Before transmission, confirm that the package includes:

• the preserved source files or a clear route to them
• any playback copies, labeled as conversions
• the investigator’s report or observation log, if it will be relied on
• a chronology with file names and timecodes
• the full observation periods, plus any highlighted excerpts
• the relevant medical records, restrictions, job information, and prior report
• a list of known gaps, assumptions, and identity information
• the exact questions for the physician

NIST’s publication on digital evidence preservation notes that digital evidence presents preservation issues beyond those associated with traditional evidence. The evidence custodian should apply the case’s preservation protocol before files are edited, compressed, or transferred.

Confirm authorization and secure transfer

Verify that sending the footage is permitted under the applicable discovery rules, orders, privacy requirements, contractual limits, and case strategy. Use a secure transfer method approved for the matter. Limit access to the people who need the material for the assigned work.

The AMA’s ethics guidance directs IME physicians to protect personal health information under professional confidentiality standards. That professional obligation does not replace counsel’s legal review, but it supports a careful transfer and access process.

Frame the cover letter around medical analysis

A good cover letter can be brief. It should orient the physician without arguing the case.

List what the physician received

Identify each video file, playback copy, observation report, medical record set, prior report, and job document. State the recording dates and the source of identity information. Note whether the full observation periods are included and whether any file has been converted.

Also state the review sequence requested, if one was agreed. If the physician should review the footage only after taking the history or completing the examination, put that instruction in a separate, clear sentence.

Use focused, non-leading questions

Ask three to five questions that can be answered medically. For example:

• Is the recorded activity medically consistent with the examination findings and the restriction identified in Dr. Smith’s May 2 note?
• Does the footage change any opinion in your June 10 report? If so, identify the opinion and explain why.
• What facts visible in the recording support your analysis?
• What limitations in duration, image quality, object weight, or context affect your interpretation?
• Is additional medical or technical information needed before you can answer?

That format gives the physician room to agree, disagree, or qualify the premise. It also produces a report that is easier to understand and defend.

Conclusion

Surveillance is most useful in an IME when it is treated as evidence to be evaluated, not a verdict to be adopted. Provide the complete material, preserve the source, index the relevant segments, pair the footage with the right medical context, and ask questions the physician is qualified to answer. A neutral process gives the examiner a stronger basis for explaining both the significance and the limits of what the camera captured.
