(1) This chapter does not affect the organization of any mutual or other insurance company or the right of the employer to insure in mutual or other companies against such liability or against the liability for the compensation provided for by this chapter.(2) An employer may provide by mutual or other insurance, by arrangement with employees or otherwise, for the payment to those employees, their families, their dependents or their representatives, of sick, accident or death benefits in addition to the compensation provided under this chapter. Liability for compensation is not affected by any insurance, contribution or other benefit due to or received by the person entitled to that compensation.(3) Unless an employee elects to receive sick leave benefits in lieu of compensation under this chapter, if sick leave benefits are paid during the period that temporary disability benefits are payable, the employer shall restore sick leave benefits to the employee in an amount equal in value to the amount payable under this chapter. The combination of temporary disability benefits and sick leave benefits paid to the employee may not exceed the employee's weekly wage.(4) Regardless of any insurance or other contract, an employee or dependent entitled to compensation under this chapter may recover compensation directly from the employer and may enforce in the person's own name, in the manner provided in this chapter, the liability of any insurance company which insured the liability for that compensation. The appearance, whether general or special, of any such insurance carrier by agent or attorney constitutes waiver of the service of copy of application and of notice of hearing required by s. 102.17.(5) Payment of compensation under this chapter by either the employer or the insurance company shall, to the extent thereof, bar recovery against the other of the amount so paid. As between the employer and the insurance company, payment by either the employer or the insurance company directly to the employee or the person entitled to compensation is subject to the conditions of the policy.(6) The failure of the assured to do or refrain from doing any act required by the policy is not available to the insurance carrier as a defense against the claim of the injured employee or the injured employee's dependents.(7)(a) The department or the division may order direct reimbursement out of the proceeds payable under this chapter for payments made under a nonindustrial insurance policy covering the same disability and expenses compensable under s. 102.42 when the claimant consents or when it is established that the payments under the nonindustrial insurance policy were improper. No attorney fee is due with respect to that reimbursement.(b) An insurer who issues a nonindustrial insurance policy described in par. (a) may not intervene as a party in any proceeding under this chapter for reimbursement under par. (a).Amended by Acts 2015 ch, 55,s 2879d, eff. 1/1/2016.1973 c. 150; 1975 c. 147 ss. 25, 54; 1975 c. 199; 1985 a. 83; 1987 a. 179. The prohibition of intervention by nonindustrial insurers under sub. (7) (b) is constitutional. An insurer is not denied a remedy for amounts wrongfully paid to its insured. It may bring a direct action the insured. Employers Health Insurance Co. v Tesmer, 161 Wis. 2d 733, 469 N.W.2d 203 (Ct. App. 1991). Although sub. (7) (a), read in isolation, authorizes the reimbursement of a subrogated insurer, when an insurer becomes subrogated by paying medical expenses arising from injuries that are compensable under this chapter, and the employer's worker's compensation insurance carrier is in liquidation, s. 646.31(11) precludes the commission from ordering the employer to reimburse the subrogated insurer for those expenses.
