Defending an Oklahoma Malpractice Suit Over a Patient's Concealed History

Attorney Answer

A patient who hid her medical history and skipped follow-up care gives you real defenses — but those are jury questions at trial, not usually grounds to get the case dismissed at the start. Early dismissal is for legal defects in the petition; "she lied on her intake form" is a fact dispute.

Oklahoma's comparative negligence statute, 23 O.S. § 13, controls the effect of her conduct. Her own negligence does not defeat her claim unless it is of greater degree than the negligence of the defendant, or of greater degree than the combined negligence of multiple defendants. Below that line it only reduces her recovery. Also know this: Oklahoma does not require a malpractice plaintiff to file an affidavit or certificate of merit. The Supreme Court struck down 12 O.S. § 19.1 in John v. Saint Francis Hospital, 2017 OK 81, 405 P.3d 681, so the absence of an expert affidavit is not a ground for dismissal.

Graham v. Keuchel, 1993 OK 6, 847 P.2d 342, cuts both ways. On the patient's own injury claim the Court held a contributory-negligence instruction was properly given where there was evidence she failed to volunteer material history that providers testified they would expect a patient to disclose even if unasked, and that whether that non-disclosure was negligence was for the jury. That is your theory. But the same decision reversed a defense judgment, holding it error to instruct that a patient's ordinary negligence was a supervening cause cutting off the provider's liability. Her conduct reduces your exposure; it does not erase it.

What you can do 1. Calendar your Answer deadline from the date you were served and file on time — an unanswered petition ends in a default judgment, and no defense saves you then. 2. Notify your malpractice carrier in writing immediately; late notice can cost you the defense and the coverage. 3. Preserve everything now: intake forms, texts about the service swap, appointment and no-show records, chart notes, and records from the other providers she saw. 4. Have counsel evaluate whether the service-swap arrangement changes anything — trading services still creates a provider-patient relationship if you rendered care. 5. Do not contact her directly about the suit.

⏱ Time limits apply. Your Answer is due on a short deadline set by the summons. Her underlying claim runs under 76 O.S. § 18, which requires an action arising out of patient care to be brought within two years of when she knew or through reasonable diligence should have known of the injury or condition — the exact dates turn on your specific facts.
