2. An injured employee whose employer’s insurer has not entered into a contract with an organization for managed care or with providers of health care services pursuant to NRS 616B.515 or 616B.527 may choose his treating physician or chiropractor from the panel of physicians and chiropractors. If the injured employee is not satisfied with the first physician or chiropractor he so chooses, he may make an alternative choice of physician or chiropractor from the panel if the choice is made within 90 days after his injury. The insurer shall notify the first physician or chiropractor in writing. The notice must be postmarked within 3 working days after the insurer receives knowledge of the change. The first physician or chiropractor must be reimbursed only for the services he rendered to the injured employee up to and including the date of notification. Any further change is subject to the approval of the insurer, which must be granted or denied within 10 days after a written request for such a change is received from the injured employee. If no action is taken on the request within 10 days, the request shall be deemed granted. Any request for a change of physician or chiropractor must include the name of the new physician or chiropractor chosen by the injured employee.

3. An injured employee [employed or residing in any county in this state] whose employer’s insurer has entered into a contract with an organization for managed care or with providers of health care services pursuant to NRS 616B.515 or 616B.527 must choose his treating physician or chiropractor pursuant to the terms of that contract. If the injured employee is not satisfied with the first physician or chiropractor he so chooses, he may make an alternative choice of physician or chiropractor pursuant to the terms of the contract if the choice is made within 90 days after his injury. If the injured employee, after choosing his treating physician or chiropractor, moves to a county which is not served by the organization for managed care or providers of health care named in the contract and the insurer determines that it is impractical for the injured employee to continue treatment with the physician or chiropractor, the injured employee must choose a treating physician or chiropractor who has agreed to the terms of that contract unless the insurer authorizes the injured employee to choose another physician or chiropractor.

4. Except when emergency medical care is required and except as otherwise provided in NRS 616C.055, the insurer is not responsible for any charges for medical treatment or other accident benefits furnished or ordered by any physician, chiropractor or other person selected by the injured employee in disregard of the provisions of this section or for any compensation for any aggravation of the injured employee’s injury attributable to improper treatments by such physician, chiropractor or other person.

The rating physician or chiropractor must be selected in rotation from the list of qualified physicians and chiropractors maintained by the administrator pursuant to subsection 2 of NRS 616C.490, unless the insurer and injured employee otherwise agree to a rating physician or chiropractor. The insurer shall pay the costs of any medical examination requested by the hearing officer.
