CO MLO · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Impairment and disability evaluation (AMA Guides framework)

  • Map the AMA Guides structural framework (chapters, rating methods, whole-person vs. regional percentages) into a one-page reference sheet from memory.

  • Calculate 6 worked impairment examples covering spine, upper extremity, and lower extremity using the DBI and range-of-motion methods.

  • Distinguish impairment, disability, and handicap in writing, with one orthopaedic example of each.

  • Identify which rating method applies to a given body region and defend the choice in 3 short vignettes.

Your checkpoint

A 10-item self-quiz on impairment rating calculations, scored, with every missed item rewritten as a corrected one-line rule.

Week 2

Impairment and disability evaluation (AMA Guides framework) & Causation, apportionment, and aggravation of pre-existing conditions

  • Apply the AMA Guides approach to apportioning impairment between pre-existing and new pathology across 5 case scenarios.

  • Define causation, aggravation, acceleration, and exacerbation and write a distinct orthopaedic example for each.

  • Explain how degenerative change on imaging can be distinguished from acute injury using objective criteria.

  • Draft a causation opinion paragraph that separates diagnosis, mechanism, and temporal relationship.

Your checkpoint

A 700-word mock causation-and-apportionment opinion for a single lumbar spine scenario, with an explicit reasoning chain.

Week 3

Orthopaedic anatomy, biomechanics, and injury mechanisms

  • Diagram the functional anatomy of the shoulder, knee, and lumbar spine, labeling the structures most often injured in compensable claims.

  • Explain the biomechanics of common injury mechanisms (axial load, valgus stress, rotator cuff impingement) in plain language.

  • Predict the tissue injured from a described mechanism in 8 short vignettes.

  • List the anatomic findings that support or undermine a claimed mechanism of injury.

Your checkpoint

An 8-vignette mechanism-to-injury worksheet with your predicted diagnosis and supporting anatomy for each.

Week 4

Diagnostic imaging and objective injury documentation

  • Interpret plain radiographs, MRI, and CT reports for the orthopaedic findings that carry rating and causation weight.

  • Distinguish objective imaging findings from subjective or non-specific descriptors in 10 report excerpts.

  • Explain the limits of imaging in proving acute injury versus chronic degeneration.

  • Write imaging findings into an objective-documentation summary without overstating certainty.

Your checkpoint

A 10-excerpt imaging interpretation log with your objective/subjective classification and rationale for each.

Week 5

Medical legal fundamentals and legal process

  • Outline the civil litigation process from injury through discovery, expert disclosure, and trial.

  • Define the legal standards for medical causation, burden of proof, and admissibility of expert opinion.

  • Explain the physician's duties and boundaries when records are subpoenaed or a report is requested.

  • Differentiate treating physician, IME physician, and expert witness roles in a written comparison.

Your checkpoint

A one-page legal-process flowchart annotated with the points where a physician's report or testimony enters the case.

Week 6

Independent medical examination and expert witness practice

  • Design a structured IME protocol covering history, examination, record review, and objectivity safeguards.

  • Draft IME report sections that separate findings, opinions, and limitations of opinion.

  • Anticipate and answer 10 cross-examination questions on IME methodology and bias.

  • Identify conflicts of interest and disclosure obligations before accepting an IME assignment.

Your checkpoint

A complete mock IME report for one case, plus a written rebuttal to 5 likely cross-examination challenges.

Week 7

Medical record review, report writing, and deposition testimony

  • Build a record-review workflow that logs source, date, author, and relevance for each document.

  • Write a report with an executive summary, findings, opinions, and a clear basis for each opinion.

  • Prepare for deposition by organizing opinions into a defensible outline with record citations.

  • Practice answering 10 deposition questions, including challenges to qualifications and methodology.

Your checkpoint

A deposition outline plus written answers to 10 anticipated questions, each tied to a record citation.

Week 8

Ethics, professionalism, and regulatory compliance & Medical legal fundamentals and legal process & Causation, apportionment, and aggravation of pre-existing conditions & Impairment and disability evaluation (AMA Guides framework)

  • Summarize ethical and regulatory obligations for expert practice, including confidentiality, honesty, and scope of opinion.

  • Reconcile the AMA Guides rating, causation opinion, and legal standard into one coherent case narrative.

  • Complete a timed 40-question mixed-domain practice set and analyze every error by domain.

  • Review weak domains and write a personal pre-exam checklist of decision rules.

Your checkpoint

A timed 40-question practice set scored at 75% or higher, with a written error analysis and final one-page decision-rule checklist.

Milestones

Week 2: Can calculate a basic impairment rating and state a causation opinion with an explicit reasoning chain, scoring at least 70% on the week 2 self-quiz.

Week 4: Can classify 8 of 10 imaging excerpts as objective or subjective and explain the rating and causation significance of each.

Week 6: Can produce a structured IME report and defend its methodology against 5 cross-examination challenges without contradicting the record.

Week 8: Scores at least 75% on the timed 40-question mixed-domain set, with no domain below 60% and a written error analysis completed.
