# Causation Language Patterns

Causation language is the highest-value text in any medical record. It is the provider's opinion on whether the claimed injury was caused by the incident. Plaintiffs need favorable causation; defendants need adverse or absent causation. Either way, this language must be surfaced in the chronology, quoted verbatim, and flagged.

## Favorable causation patterns (plaintiff)

These phrases or constructions typically support causation. Quote them verbatim and surface in Strategic Analysis.

- "Causally related to..."
- "Consistent with the mechanism of injury described..."
- "Within a reasonable degree of medical probability/certainty..."
- "More likely than not..."
- "Direct result of..."
- "Attributable to the [date] incident..."
- "Aggravation of pre-existing condition by..."
- Temporal language tying onset to incident: "symptoms began immediately after..."
- "No prior history of [same complaint]..."
- "The patient's presentation is consistent with..."

## Adverse causation patterns (defense)

These weaken causation. Quote and surface in Strategic Analysis under Adverse Findings.

- "Pre-existing..."
- "Degenerative..."
- "Chronic..."
- "Long-standing..."
- "Multifactorial..."
- "Unrelated to..."
- "Cannot be attributed solely to..."
- "Idiopathic..."
- "Symptoms predate the incident..."
- "Inconsistent with mechanism described..."
- "Symptom magnification..."
- "Non-physiologic findings..."
- "Waddell's signs positive..."
- "Secondary gain considerations..."

## Aggravation language

This is its own category and is often dispositive. Aggravation of a pre-existing condition is generally compensable, but the chronology must surface the language clearly so the attorney can argue eggshell plaintiff.

- "Aggravation of..."
- "Acceleration of..."
- "Exacerbation of underlying..."
- "Lit up a previously asymptomatic..."
- "Made symptomatic a previously..."

When this language appears, capture it in both the encounter entry and Strategic Analysis. Distinguish:

- **Temporary aggravation** ("returned to baseline by [date]"): limits damages
- **Permanent aggravation** ("not expected to return to baseline"): supports full damages
- **Acceleration** ("would have become symptomatic eventually but the incident accelerated by [time]"): partial damages

## Where to look

Causation language clusters in specific sections of medical records. Prioritize retrieval from:

- Initial consult notes (especially with specialists referred for the injury)
- Independent Medical Examination (IME) reports - these are written specifically to opine on causation
- Functional Capacity Evaluations (FCE) - usually opine on permanency
- Treating physician narrative reports - often prepared at attorney request
- Discharge summaries from inpatient stays
- Closing notes when patient reaches MMI (Maximum Medical Improvement)

Causation language rarely appears in routine progress notes. If you are not finding any in a long records production, the attorney probably needs to request a narrative report from the treating physician.

## How to surface

In the encounter entry, use a dedicated "Causation language" subsection with the verbatim quote in quotation marks and a Bates citation. Do not paraphrase causation statements. The exact words matter for cross-examination.

In the Strategic Analysis section, repeat the most important causation quotes under Favorable Findings or Adverse Findings (or both, if the same record contains both). Cross-reference back to the date and Bates location.

Example in the chronology:

```
Causation language: "It is my opinion within a reasonable degree of medical
probability that Ms. Smith's L4-L5 disc herniation was caused by the motor
vehicle collision of March 8, 2024, based on the temporal relationship between
the incident and onset of symptoms, the mechanism of injury, and the absence of
documented prior lumbar complaints." [SMITH00892]
```

Example in Strategic Analysis:

```
Favorable findings:
- Dr. Chen offered explicit causation opinion connecting L4-L5 herniation to
  the 2024-03-08 collision within a reasonable degree of medical probability.
  [SMITH00892, encounter dated 2024-04-22]
```

## Inconsistent causation across providers

When different providers offer different causation opinions, this is significant. Surface the conflict in Strategic Analysis under Inconsistencies, with both quotes and both Bates citations. Do not resolve the conflict yourself; that is the attorney's job at deposition.
