If the affidavit or declaration is to be so used, it must be submitted in the manner prescribed in NRS 616C.355.

3. No compensation is payable for the death, disability or treatment of an employee if the employee’s death is caused by, or insofar as the employee’s disability is aggravated, caused or continued by, an unreasonable refusal or neglect to submit to or to follow any competent and reasonable surgical treatment or medical aid.
4. If any employee persists in an unsanitary or injurious practice that imperils or retards his or her recovery, or refuses to submit to such medical or surgical treatment as is necessary to promote his or her recovery, the employee’s compensation may be reduced or suspended.
5. An injured employee’s compensation, other than accident benefits, must be suspended if:

(b) It is within the ability of the employee to correct the nonindustrial condition or injury.
The compensation must be suspended until the injured employee is able to resume treatment, testing or examination for the industrial injury. The insurer may elect to pay for the treatment of the nonindustrial condition or injury.
