Pre-Existing Condition Cases for Plaintiffs: The Concessions That Beat the Natural Progression Defense

A client with a prior injury, degenerative findings, or a documented medical history hands the insurer its favorite defense. The natural progression argument and percentage apportionment claims arrive through a defense medical expert and a selective IME report. Minimizing the history no longer works. The winning move is to own the pre-existing condition and build the aggravation record first.

The stakes start before the demand goes out. Pick the wrong doctrinal frame between eggshell and crumbling skull and the record rests on the wrong foundation. Send a demand without a defensible pre-accident baseline and the natural progression defense fills the gap. Leave chart notes unconnected to causation opinions and the IME report controls the story. Let financial bias and cherry-picked record review go unchallenged and apportionment cuts the recovery.

This two-session program gives plaintiff attorneys a pre-demand checklist covering doctrine, medical records, treatment continuity, and demand framing for aggravation cases. Attendees leave with the demand-letter concession strategy and a complete deposition outline targeting the four major vulnerabilities in a typical IME report. The outline runs from selective record review and financial bias to sequenced concessions and the Daubert setup.
