(a) For purposes of this section, “controverted claim” means any claim in which compensation is denied either in whole or in part by the workers’ compensation carrier or the employer, if self-insured.

(b) Any insurer, hospital service corporation, medical service corporation, health care center or employee welfare benefit plan that furnished benefits or services under a health insurance policy or a self-insured employee welfare benefit plan to any person suffering an injury or illness covered by the Workers’ Compensation Act has a lien on the proceeds of any award or approval of any compromise made by an administrative law judge less attorneys’ fees approved by the district administrative law judge and reasonable costs related to the proceeding, to the extent of benefits paid or services provided for the effects of the injury or illness arising out of and in the course of employment as a result of a controverted claim, provided such plan, policy or contract provides for reduction, exclusion, or coordination of benefits of the policy or plan on account of workers’ compensation benefits.

(c) The lien shall arise at the time such benefits are paid or such services are rendered. The person or entity furnishing such benefits or services shall serve written notice upon the employee, the insurance company providing workers’ compensation benefits or the employer, if self-insured, and the administrative law judge for the district in which the claim for workers’ compensation has been filed, setting forth the nature and extent of the lien allowable under subsection (b) of this section. The lien shall be effective against any workers’ compensation award made after the notice is received.

(d) The written notice shall be served upon the employee at his last-known address, the insurance company at its principal place of business in this state or the employer, if self-insured, at its principal place of business, and the administrative law judge, at the district office. Service shall be made to all parties by certified or registered mail. The notice shall be in duplicate and shall contain, in addition to the information set forth in subsection (c) of this section, the name of the injured or ill employee, the name of the company providing workers’ compensation benefits, the amount expended and an estimate of the amount to be expended for benefits or services provided to such injured or ill employee.

(e) The insurance company providing workers’ compensation coverage or the employer, if self-insured, shall reimburse the insurance company, hospital service corporation, medical service corporation, health care center or employee welfare benefit plan providing benefits or service directly, to the extent of any such lien. The receipt of such reimbursement by such insurer, hospital service corporation, medical service corporation, health care center or employee welfare benefit plan shall fully discharge such lien.

(f) The validity or amount of the lien may be contested by the workers’ compensation carrier, the employer, if self-insured or the employee by bringing an action in the superior court for the judicial district of Hartford or in the judicial district in which the plaintiff resides. Such cases shall have the same privilege with respect to their assignment for trial as appeals from the workers’ compensation review division but shall first be claimed for the short calendar unless the court shall order the matter placed on the trial list. An appeal may be taken from the decision of the Superior Court to the Appellate Court in the same manner as is provided in § 51-197b. In any appeal in which one of the parties is not represented by counsel and in which the party taking the appeal does not claim the case for the short calendar or trial within a reasonable time after the return day, the court may of its own motion dismiss the appeal, or the party ready to proceed may move for nonsuit or default as appropriate. During the pendency of the appeal any workers’ compensation benefits due shall be paid into the court in accordance with the rules relating to interpleader actions.
