Wis. Stat. § 893.12
The period fixed for the limitation for the commencement of actions, if a payment is made as described in s. 885.285(1) , shall be either the period of time remaining under the original statute of limitations or 3 years from the date of the last payment made under s. 885.285(1) , whichever is greater.
Wis. Stat. § 893.12
Any payment made in advance or settlement of either personal injury or property damage claims, when the plaintiff has both, extends the limitation for a personal injury claim, if it is made within the three-year limit period of s. 893.54(1). Abraham v. Milwaukee Mutual Insurance Co., 115 Wis. 2d 678, 341 N.W.2d 414 (Ct. App. 1983). This section does not apply to foreign causes of action. Section 893.07(1) prevents this section from extending foreign statutes of limitation. Thimm v. Automatic Sprinkler Corp., 148 Wis. 2d 332, 434 N.W.2d 842 (Ct. App. 1988). The tolling provision applies only to the party that received a settlement or advance payment under s. 885.285. It does not apply to a stranger to the settlement. Riley v. Doe, 152 Wis. 2d 766, 449 N.W.2d 83 (Ct. App. 1989). For a period of limitations to be extended under this section as the result of a "payment" by check, the check must be accepted and negotiated. Parr v. Milwaukee Bldg. & Const. Trades, 177 Wis. 2d 140, 501 N.W.2d 858 (Ct. App. 1993). To be a payment under s. 885.285 that will toll or extend the statute of limitations, a payment must be related to fault or liability. Gurney v. Heritage Mutual Insurance Co., 188 Wis. 2d 68, 523 N.W.2d 193 (Ct. App. 1994). The waiver by the defendant medical provider in a medical malpractice action of the copayment portion of the amount due for the plaintiff's medical treatment did not constitute a payment under this section or s. 885.285. Young v. Aurora Medical Center, 2004 WI App 71, 272 Wis. 2d 300, 679 N.W.2d 549, 03-0224.
