Wisconsin does not have a standalone fraudulent concealment tolling statute. Concealment by a defendant is addressed through two overlapping doctrines: (1) the common law discovery rule (Hansen v. A.H. Robins, 1983), under which the SOL does not accrue until the plaintiff discovers or should discover both the injury and its probable cause — active concealment by a defendant delays this discovery and thus delays accrual; (2) equitable estoppel, recognized in Kohnke v. St. Paul Fire & Marine Ins. Co., 147 Wis.2d 354 (1988), as a distinct theory (under sec. 893.55(2) for health care providers; under equitable estoppel principles for general tort claims). For medical malpractice, Wis. Stat. § 893.55(2) codifies a specific concealment provision: 'If a health care provider conceals from a patient a prior act or omission of the provider which has resulted in injury to the patient, an action shall be commenced within one year from the date the patient discovers the concealment or, in the exercise of reasonable diligence, should have discovered the concealment or within the time limitation provided by sub. (1), whichever is later.'

893.16(1) (1) If a person entitled to bring an action is, at the time the cause of action accrues, either under the age of 18 years, except for actions against health care providers; or mentally ill, the action may be commenced within 2 years after the disability ceases, except that where the disability is due to mental illness, the period of limitation prescribed in this chapter may not be extended for more than 5 years.
