  (1)  In cases in which the act of neglect complained of is introducing and negligently permitting any foreign object to remain within the body of a living person, the action shall be brought within two years from the date of the discovery of such alleged negligence, or from the date on which the patient in the exercise of ordinary care should have discovered such alleged negligence, whichever date first occurs; and

(1985) The reduction of the limitation period for medical malpractice actions should be applicable only to claims where the alleged act of malpractice occurred after the effective date of the section. Goodman v. St. Louis Children's Hosp., 687 S.W.2d 889 (Mo. banc).

(1985) The ten-year maximum was designed to limit the "foreign object" exception to the two year statute, and not to limit the time within which an infant who suffers damage from malpractice within his first two years may file suit. McLeran v. St. Luke's Hosp. of Kansas City, 687 S.W.2d 892 (Mo. banc).

(1996) Actions brought pursuant to this section are not tolled under 516.170.  Batek v. Curators of Univ. of Mo., 920 S.W.2d 895 (Mo. banc).

(2015) Ten-year statute of repose could not be equitably tolled and does not violate constitutional provisions of equal protection, open courts, due process, or special laws.  Ambers-Phillips v. SSM DePaul Health Center, 459 S.W.3d 901 (Mo. banc).

(2023)  The specific deadline in Section 516.105 for service of process in medical malpractice claims does not conflict with the requirement that service of process be prompt under Rule 54 of the Missouri Supreme Court Rules of Civil Procedure.  Brick v. Koeppen, 672 S.W.3d 62 (Mo.App.S.D.)
