MO HB596

Amends Missouri Section 490.715 to change evidentiary rules for medical treatment costs in civil litigation, replacing "value" of medical treatment with "cost" as the standard for evidence

Pre-trial payments by a defendant or their insurer toward a plaintiff's special damages become inadmissible and non-recoverable from that defendant, rather than allowing defendants to introduce evidence that third parties made such payments

Defendants who make pre-trial payments lose the right to receive a credit against a judgment under Section 490.710, unless those payments were included in the plaintiff's claim for special damages at trial

Limits medical cost evidence to actual amounts paid plus any unpaid projected amounts to be paid by any source to satisfy the healthcare provider's financial obligation

Prohibits presentation of billed charges to juries; evidence must be presented solely in terms of actual or projected costs necessary to satisfy treatment costs under any agreement with the provider
