39-71-402. Extraterritorial applicability and reciprocity of coverage -- agreements with other states -- rulemaking. (1) (a) In the absence of an agreement under subsection (2), if a worker employed in this state who is subject to the provisions of this chapter temporarily leaves this state incidental to that employment and receives an injury arising out of and in the course of employment, the provisions of this chapter apply to the worker as though the worker were injured within this state.
     (b) Except as provided in subsection (1)(c) and in the absence of an agreement under subsection (2), if a worker from another state and the worker's employer from another state are temporarily engaged in work within this state, this chapter does not apply to them:
     (i) if the employer and employee are bound by the provisions of the workers' compensation law or similar law of the other state that applies to them while they are temporarily engaged in work in the state of Montana; and
     (ii) if the Workers' Compensation Act of this state is recognized and given effect as the exclusive remedy for workers employed in this state who are injured while temporarily engaged in work in the other state.
     (c) Unless specifically addressed in an agreement as provided in subsection (2)(d), employers from another state that are engaged in the construction industry, as defined in 39-71-116, and that employ workers from another state shall obtain coverage for those workers under the provisions of this chapter.
     (2) (a) The department, with the approval of the governor, may enter into a reciprocal agreement with an authorized officer of the workers' compensation department or similar agency of another state to allow an employer from one state and its employees from that state to work in the other state without obtaining workers' compensation coverage from both states.
     (b) The reciprocal agreement must contain, at a minimum, the following provisions:
     (i) the employer and employee must be bound by the provisions of the workers' compensation law or similar law of the other state that applies to them while they are engaged in work in the state of Montana; and
     (ii) the Workers' Compensation Act of this state must be recognized and given effect as the exclusive remedy for workers employed in this state who are injured while engaged in work in the other state.
     (c) The agreement may contain other provisions, including but not limited to provisions regarding how long the work may continue and whether limitations or exclusions apply to the types of work covered by the agreement.
     (d) Unless the agreement specifically provides that the agreement is applicable to employers engaged in the construction industry, as defined in 39-71-116, an employer from another state engaged in the construction industry in Montana does not qualify for extraterritorial coverage that might otherwise be provided by this section.
     (e) The agreement may be canceled, renewed, or modified from time to time as provided in the agreement.
     (f) After an agreement has been entered into pursuant to this subsection (2), a certificate from an authorized officer of the workers' compensation department or similar agency of another state certifying that an employer of the other state is bound by the Workers' Compensation Act of the state and that its act will be applied to employees of the employer while engaged in work in the state of Montana is prima facie evidence that:
     (i) the workers' compensation law of the certifying state applies to the employer and its employees while engaged in work in Montana; and
     (ii) the employer is properly insured for workers' compensation purposes in the certifying state as of the date of the certification.
     (3) The department may adopt rules to implement this section.
