Wis. Stat. § 655.245: Insurance policy limitations.

(1) No policy of health care liability insurance may permit a health care provider to reject any settlement agreed upon between the claimant and the insurer.

(2) A policy of health care liability insurance may permit the insurer to make payments for medical expenses prior to any determination of fault. Such payments are not an admission of fault. Such payments may be deducted from any judgment or arbitration award, but shall not be repaid regardless of the judgment or award. Nothing in this subsection shall restrict the insurer’s right of comparative contribution or indemnity in accordance with the laws of this state.
